Review: Lexus S190.I GS 300, GS 430 and GS 450h (2005-08)

Overview

Released in March 2005, the Lexus S190 Series I (S190.I) GS was a mid-size, rear-wheel drive range of sedans. Manufactured in Tahara, Japan, the Lexus S190 GS range initially consisted of the GS 300 and GS 430, powered by 3.0-litre V6 and 4.3-litre V8 engines respectively.

GS 300 and GS 430: 3GR-FSE and 3UZ-FE engines

Of the engines,

• The 3.0-litre 3GR-FSE V6 petrol engine had a die-cast aluminium block, direct fuel injection, double overhead camshafts (per cylinder bank), four valves per cylinder, variable inlet and exhaust valve timing (‘Dual VVT-i’) and a compression ratio of 11.5:1; and,
• Compared the 3GR-FSE engine, the 4.3-litre 3UZ-FE V8 omitted direct injection, had variable intake valve timing only (‘VVT-i’) and operated at a lower compression ratio of 10.5:1.

Lexus GS 450h: 2GR-FSE engine and electric motor

In May 2006, the range was expanded with the hybrid GS 450h, which was powered by a direct-injection, 3.5-litre 2GR-FSE V6 petrol engine and a 650 volt permanent magnet electric motor which could operate independently and in tandem. Via planetary reduction gears, the power transmission unit would combine and re-allocate power from the engine, electric motor and generator according to operational requirements. Through two-stage motor speed reduction gearing, the continuously variable transmission could also provide maximum low-gear torque for acceleration and extended high-gear performance for fuel-efficient cruising. Furthermore, the driver could select from three drive settings: Normal, Power, Snow and Sport.

Dimensions and suspension

Relative to the Lexus S160 GS , the S190 GS was 20 mm longer (4825 mm), 20 mm wider (1820 mm), 15 mm lower (1430 mm) and had a 50 mm longer wheelbase (2850 mm). Furthermore, the S190 GS was fitted with double wishbone front suspension and multi-link rear suspension (both with coil springs, gas-filled dampers and anti-roll bars).

Safety equipment

Standard safety equipment for the S190 GS included dual front airbags, side airbags for front and rear occupants, curtain airbags for front and rear occupants, knee airbags for driver and passenger, ABS, brake assist, electronic brake force distribution, electronic stability control, traction control and front seatbelts with pretensioners and load limiters.

The GS 300 Sport Luxury, GS 430 and GS 450h were also equipped with a pre-collision system. In the event that a collision was anticipated – which included the radar sensors in the active cruise control system – the pre-collision system would pretension the seatbelts and, if necessary, prepare the brake assist system.

The GS 430 Sports Luxury and GS 450h were also fitted with a Vehicle Dynamics Integrated Management (VDIM) system which enabled intuitive counter-steering – without driver input – to prevent the driver from losing control.

Brakes

The S190 GS had 334 mm by 30 mm spiral-fin ventilated front brake discs with four-piston opposed aluminium monobloc calipiers and 310 mm by 18 mm ventilated rear discs with single-piston calipers.

Euro NCAP crash testing

In Euro NCAP crash testing , the GS 300 received a five star adult occupant protection rating with a score of 34.81 out of 37. In the frontal offset test, there was a slight risk of chest and lower leg injury for the driver. In the side impact and pole tests, however, maximum points were awarded.

Features: GS Sports and Sports Luxury

Standard features for the GS 300 Sports included 17-inch alloy wheels, a ten speaker sound system with a six-stack CD player, dual-zone climate control air conditioning, leather seats, power adjustable and heated front seats, cruise control, front fog lamps, adaptive front headlights, a rear vision camera, automatic headlights, rain sensing wipers, Bluetooth mobile phone connectivity, remote central locking and proximity key, power windows and mirrors, a height and reach adjustable steering wheel, an electrochromatic rear view mirror, front seat memory settings, a trip computer, an alarm and immobiliser.

Beyond this, the GS 300 Sports Luxury added a fourteen speaker Mark Levinson sound system with MP3/WMA compatibility, a satellite navigation system, radar-controlled active cruise control (i.e. with autonomous braking), front and rear parking sensors, rear fog lamps and a power moonroof.

The GS 430 Sports Luxury was further equipped with 18-inch alloy wheels, Adaptive Variable Suspension (Lexus’ AVS) and variable gear ratio steering; the GS 450h was further distinguished by its DVD player, perforated leather seats and a park assist display.

• The 2.5-litre 4GR-FSE V6 engine had an aluminium block and cylinder head, direct-injection, double overhead camshafts (per cylinder bank), four valves per cylinder, variable intake and exhaust valve timing, an electronically-controlled acoustic induction system (ACIS) and a compression ratio of 12:1; and,
• Compared to the 4GR-FSE engine , the 3.5-litre 2GR-FSE engine simultaneously combined direct injection with traditional port injection for more precise air/fuel mixing under low and medium load conditions. Furthermore, ACIS was omitted and the compression ratio was reduced to 11.8:1.

Hybrid powertrains: GS 300h and GS 450h

For the GS 300h and GS 450h, both the 2.5-litre 2AR-FSE four-cylinder and 3.5-litre 2GR-FXE V6 Atkinson cycle engines had double overhead camshafts (DOHC), direct and port injection (D-4S), variable intake and exhaust valve timing (dual VVT-i), and compression ratios of 13.0:1. Furthermore, both the hybrid powertrains included:

• Two electric motors with one to act primarily as a generator and the other as the main drive motor;
• A water-cooled, 650-volt permanent magnet electric motor which drew power from nickel metal hydride (Ni-MH) batteries positioned under the luggage deck board; and,
• A planetary-gear continuously variable transmission (CVT) with six pre-set ratios that could be selected via steering wheel gearshift paddles.

The GS 300h and GS 450h enabled the driver to select from five drive modes – 

• ‘EV’ (electric vehicle) mode: provided up to 2 km of range with a maximum speed of 50 km/h;
• ‘Eco’ mode: voltage for the hybrid system was generally limited to 500 volts, engine shut-down times were increased, throttle response was dulled and air conditioner and compressor fan speeds were reduced;
• ‘Normal’: provided standard throttle response;
• ‘Sport’: voltage for the hybrid system was increased to 650 volts, throttle and transmission responses were more aggressive; and,
• ‘Sport+’: firmer suspension damper settings, more direct steering, additional rear wheel steering and less intrusive stability control settings.

Dimensions

Compared to the Lexus S190 GS , the L10 GS was 22 mm longer (at 4850 mm), 19 mm narrower (1840 mm) and 30 mm taller (1455 mm), though wheelbase length was unchanged (2850 mm). Furthermore, the L10 GS achieved a 14 per cent increase in torsional rigidity through the increased use of ultra-high strength tensile steel, more spot welds and targeted laser welds.

Suspension

The Lexus L10 GS had double wishbone front suspension with forged aluminium upper and lower arms and independent, multi-link rear suspension. F Sport and Sports Luxury variants were also fitted with ‘Adaptive Variable Suspension’ (AVS) which provided simultaneous control of the damping force to all four wheels; drivers could also increase damper force via the ‘Sport+’ drive setting.

Safety equipment

Standard safety equipment for the Lexus L10 GS included dual front airbags, driver’s knee airbag, front and rear side airbags, full-length curtain airbags, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, active front seat head restraints and front seatbelts with pretensioners and load limiters. Also fitted as standard, the Blind Spot Monitor (BSM) system was activated once the vehicle exceeded 40 km/h and used sensors in the rear bumper to detect vehicles in adjacent lanes.

The GS 350 F Sport, GS 450h F Sport and all Sports Luxury variants were equipped with the ‘Lexus Advanced Pre-Collision Safety System’ (PCS) which included:

• Collision Warning;
• Pre-Collision Brake Assist;
• Pre-Collision Braking (i.e. autonomous emergency braking or AEB);
• Pre-Collision seatbelt tensioning; and,
• For the GS 350 F Sport, collision avoidance support via the Dynamic Rear Steering (DRS) system.

The Sports Luxury variants were also fitted with a driver fatigue monitor that continuously monitored the driver’s eye and head movements and could provide audible and visual warnings.

From November 2013, all GS Sports Luxury variants were fitted with a Lane Keep Assist system which could detect when the driver unintentionally drifted out of their lane and warn the driver via steering wheel vibrations and an audible tone.

From October 2014, all GS models were fitted with a Rear Cross Traffic Alert (RCTA) system as standard; the RCTA system could detect approaching vehicles as the GS was reversing.

Features: GS Luxury

Standard features for the GS 250 Luxury included 17-inch alloy wheels, a twelve speaker sound system with digital radio (DAB+), a CD/DVD player, auxiliary inputs (3.5mm/USB/iPod) and Bluetooth audio streaming, dual-zone climate control air conditioning, satellite navigation, ten-way power adjustable and ventilated front seats, leather trim, cruise control, directional bi-xenon headlights with washers, automatic headlights, rain-sensing wipers, front and rear parking sensors, a reversing camera, Bluetooth mobile phone connectivity with voice recognition, a multi-function steering wheel with gearshift paddles, remote central locking with proximity key, power windows and heated mirrors with folding function, a height and reach adjustable steering wheel, driver’s seat and mirror memory settings, an electrochromatic rear-view mirror, tyre pressure monitoring, ambient lighting, a trip computer, alarm and an immobiliser.

The GS 350 Luxury was further equipped with 18-inch alloy wheels, while the GS 450h Luxury added a fifteen-way power adjustable driver’s seat, head-up display, moonroof and adaptive suspension. The adaptive suspension system provided simultaneous control of the damping force to all four wheels to improve ride comfort and stability.

In November 2013, the head-up display (HUD) was upgraded so that it projected vehicle speed, navigation, audio information onto the windscreen in full colour.

Features: GS F Sport

Compared to the GS 250 Luxury, the GS 250 F Sport was further equipped with 19-inch alloy wheels, adaptive sports suspension and sixteen-way adjustable contoured front sports seats.

Review: Lexus L10.II GS (2015-20)

Overview

Released in Australia in December 2015, the Lexus L10 Series II (L10.II) GS introduced a revised line-up as the GS 200t replaced the GS 250. The Lexus L10.II GS could be identified by its more pronounced spindle grille, bi-LED headlights, 20 mm lower rocker moulding, revised rear bumper and more aggressively profiled rear combination lamps with chrome-plated mouldings for the outer lens.

Body

For the Lexus L10.II GS, the following changes were introduced for a more rigid body:

• 188 additional spot-welds were applied to the frame to improve panel-coupling rigidity. These spot welds were concentrated on the cowl, the junction of the rocker panels and B-pillar, and the rear shelf;
• An additional 22.5 metres of body adhesive was applied; and,
• The door surrounds had an additional 132 laser-screw welding points.

For a quieter interior, sound absorbing material was added to the upper cowl area. Underbody aerodynamics were also improved by positioning the bottom edge of the front bumper 10 mm further forward to adjust the volume of air passing under the floor.

Suspension and steering

For the Lexus L10.II GS, the front and rear suspension both had a new calibration for the coil springs, while front stabiliser bar shape and characteristics were modified. Furthermore, the shape of the free piston in the conventional and AVS damper units (for the GS F Sport and Sports Luxury) was revised for improved response.

Beyond this, the Lexus GS 200t and GS 350 were fitted with a ‘performance damper’ between the left and right front #2 braces/members to reduce vibration, increase stability and enhance steering response. The GS 200t and GS 350 were also fitted with a Torsen limited slip differential as standard.

For the GS Luxury, the damper for the intermediate steering shaft was omitted to increase steering rigidity.

Interior

Inside, the Lexus L10.II GS featured an updated multimedia system (with ‘enter’ buttons on the Remote Touch Interface), full-screen map capability for the 12.3-inch display (on F Sport and Sports Luxury variants), a larger 4.2-inch multi-information display and new seat trim with horizontal quilting seams on the seat-backs and accent grain in the seat sides. Furthermore, the analogue clock in the dashboard was housed in a single ingot of aluminium and had GPS functionality for adjusting the time zone.

GS 200t: 8AR-FTS engine

Shared with the Lexus NX 200t and XE30 IS 200t , the 2.0-litre 8AR-FTS petrol engine had an aluminium block and aluminium cylinder head, direct and port injection (Toyota’s ‘D-4S’), a twin-scroll turbocharger (which provided maximum boost pressure of 17 psi or 1.17 bar), an integrated exhaust manifold, double overhead camshafts and four valves per cylinder.

While the exhaust valves had standard variable valve timing (Variable Valve Timing with Intelligence, or ‘VVT-i’), the intake valves had a mid-position camshaft lock mechanism which retards the continuously variable valve timing, known as Variable Valve Timing-intelligent Wide (VVT-iW). The ability to retard intake valve timing enables the engine to use:

• An Atkinson cycle for low-rev operations to minimise fuel consumption; and,
• An Otto cycle at higher engine speeds for greater power.

The 8AR-FTS engine had a ‘stop-start’ system which enabled it to shut down when the vehicle is stationary in traffic to reduce fuel consumption. Unlike other systems, engine start-up was delayed until the accelerator pedal was activated (while in Brake Hold mode) to maximise fuel savings.

Safety equipment

As standard, the Lexus L10.II GS was fitted with the ‘Lexus Safety System +’ which combined –

• Pre-Collision Safety System (PCS) including Autonomous Emergency Braking: used a millimetre-wave radar and front-facing camera to detect vehicles and pedestrians. PCS could then warn the driver of a possible collision and initiate automatic emergency braking (AEB) if necessary;
• All-Speed Active Cruise Control: monitored the distance to the vehicle ahead and could maintain a set distance by controlling vehicle acceleration and braking;
• Lane Keeping Assist (LKA): operated All-Speed Cruise Control was engaged and included:
  • Lane Departure Warning (LDW): used a lane recognition camera sensor mounted near the interior mirror to monitor the vehicle’s position on the road. If the sensor detected that the vehicle had deviated from its position, the driver was alerted via steering wheel vibrations and a warning message is displayed on the multi-information screen;
  • Lane Departure Warning+ (LDW+): if the LDW determined that the LX 570 had deviated from its current lane and the audio-visual warnings had been issued, LDW+ would apply force to the steering wheel to make a correction and avoid lane departure; and,
  • Sway Warning System (SWS): monitored the vehicle’s position within the lane and the driver’s steering operations to detect sway, which could be caused by driver fatigue or inattention. If detected, the system would alert the driver by sounding a buzzer and displaying a warning on the multi-information display.

As standard, the Lexus L10.II GS was also fitted with:

• Blind Spot Monitor (BSM): operating at speeds above 40 km/h, the BSM used two radar sensors to detect other vehicles in the adjacent lanes. If detected, the driver was alerted via illuminating LED indicators in the relevant door mirror;
• Rear Cross Traffic Alert (RCTA): used the same radar sensors and warned the driver of approaching vehicles that may cross the vehicle’s path when the driver was reversing; and,
• Adaptive High Beam (AHB): automatically switched the headlights between high and low beam to avoid dazzling other road users.

Features: GS Luxury

Standard features for the Lexus GS 200t Luxury and GS 300h Luxury included 17-inch nine-spoke alloy wheels with 225/50 R17 tyres, twelve (12) speaker sound system, digital radio tuner (DAB+), eight-inch navigation display screen, ten-way power adjustable front seats with driver’s seat memory settings, leather-accented seats, heated and ventilated front seats, LED headlights with automatic high beam, LED daytime running lamps, LED front fog lamps, reversing camera with guidelines, rear parking sensors, automatic headlights, rain-sensing wipers, leather-accented steering wheel and gear shifter, remote central locking with proximity card (i.e. keyless entry), power windows, power adjustable and heated door mirrors with memory settings, push-button start, an electrochromatic rear view mirror, tyre pressure monitoring and an immobiliser.

Features: GS F Sport

Relative to the GS Luxury, the Lexus GS 200t F Sport and GS 300h F Sport were further equipped with 19-inch alloy wheels with a dark metallic grey finish, 235/40 R19 front and 265/35 R19 rear tyres, eighteen-way power adjustable driver’s seat, ‘F Sport’ front seats, LED high grade headlights with Adaptive High Beam, ‘F Sport’ steering wheel and gear shifter, Naguri-style aluminium ornamentation, powered rear sunshade and F Sport pedals.

Beyond this, the GS 350 F Sport added a Mark Levinson premium audio system, 12.3-inch multimedia display and Head-Up Display. For the L10.II GS, the Mark Levinson audio system was updated with Clari-Fi to enhance the reproduction of compressed audio files.

Furthermore, the Drive Mode Select system for the Lexus L10.II GS F Sport and Sports Luxury variants gained a ‘Customize’ feature which enabled the driver to select settings not available in the Normal, Eco, Sport S and Sport S+ modes.

Features: GS Sports Luxury

The Lexus GS 350 Sports Luxury and GS 450h Sports Luxury were distinguished by their combination machine-finish and mesh spoke alloy wheels, semi-aniline leather-accented trim, heated rear seats, heated steering wheel, HVAC (heating, ventilation and air conditioning) control panel for rear passengers and power-operated boot lid.

Unique laser cut ornamentation which incorporated crafted wood and aluminium was also available as a no-cost option.

Review: FPV FG.I GS (2009-11)

Overview

Released in August 2009, the FPV FG Mk.I (FG.I) GS was a rear-wheel drive, performance sedan. Manufactured in Campbellfield, Victoria, the GS was initially powered by a 5.4-litre V8 petrol engine that was mated to either six-speed automatic or manual transmissions. In October 2010, however, the 5.4-litre V8 petrol engine was replaced with a 5.0-litre supercharged V8 unit due to the introduction of Euro IV emissions standards.

Boss 302 and Boss 315 engines

Of the engines,

• The 5.4-litre Boss 302 V8 petrol engine had a cast iron block, cast aluminium cylinder head, forged steel crankshaft, cross-bolted main bearing caps, sintered connecting rods, double overhead camshafts (DOHC) per cylinder bank, roller finger followers, four valves per cylinder, twin knock sensors, coil on plug ignition and a compression ratio of 11.0:1. Compared to Boss 315 engine in the FPV GT Series, the Boss 302 engine differed in that it had a recalibrated ECU and lower 6000 rpm maximum engine speed; and,
• Developed in Australia by Prodrive at a cost of $36 million, the 5.0-litre Boss 315 Miami V8 engine was based on Ford’s Coyote V8 engine that was introduced in the 2010 Ford Mustang GT. The hand-built Miami V8 engine had an aluminium block and cylinder head, an HTV 1900 supercharger (developed by Harrop Engineering and using Eaton Twin Vortices Series technology) providing maximum boost pressure of 0.34 bar (4.93 psi), a forged steel crankshaft, powder sintered forged connecting rods, double overhead camshafts, variable intake camshaft timing, roller finger followers, four valves per cylinder, and a compression ratio of 9.25:1. Due to its aluminium construction, the supercharged Boss 315 engine was 47kg lighter than the Boss 302.

Transmissions

The FPV GS was available with six-speed Tremec TR6060 manual or six-speed ZF 6HP26 automatic transmissions.

Replacing the Tremec T56 manual transmission, the Tremec TR6060 had triple synchromesh on first and second gears and double synchromesh on all other gears (including revrese) which reduced gear shift efforts and shift travel. The reduced shift travel also provided increased space for the use of larger, stronger gears for greater durability.

The FPV GS was fitted with the high-performance ZF 6HP26 transmission which was rated for 600 Nm applications and had upgraded clutches with extra plates in the clutch packs. For the FG range, the 6HP26 transmission had a cylinder cut function whereby the fuel injectors would be deactivated during gearshifts to reduce shift times.

For the supercharged Boss 315 engine,

• The TR6060 transmission was fitted with a new bell-housing to suit a new twin-plate clutch system (shared with the Mustang GT500) and revised second gear synchros were implemented; and,
• The 6HP26 transmission was upgraded with a new 7-plate clutch pack and 4-planet planetary gearset for improved torque capacity.

Dimensions

The FG GS was 4956 mm long, 1868 mm wide, 1466 mm tall and had a 2836 mm long wheelbase.

Suspension

The FG GS’s double wishbone front suspension had two lower ball joints that connected the separate lower arms to the suspension knuckle. These two lower links created a virtual pivot of the lower arm – hence the ‘Virtual Pivot Control Link’ name – and allowed the suspension to behave as though the lower pivot point was at the intersection of the two arms. Due to the use of aluminium and high strength steels, the Virtual Pivot Control Link suspension was 22 kg lighter than that in the BF GT .

The independent rear suspension (IRS) had three control arms:

• A forged upper control arm;
• A stamped front lower control arm; and,
• A stamped rear lower control arm.

Each control arm had a cross axis ball joint on the wheel assembly end and was attached to the subframe and knuckle. Furthermore, the ‘Control Blade’ was a stamped trailing arm which provided lateral support and acted as a vertical pivot point.For the FG GS, the roll centre height was increased to reduce in-corner roll and improve straight line stability, while toe-angle was revised to improve steering feel and stability.

Safety equipment

Recalls: Lexus S190 GS

Overview

Manufacturers, or importers, issue recalls for defects or faults which have the potential to cause injury. Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.

Recalls: Lexus S190 GS

• In April 2006, a recall was issued for Lexus GS 300 and GS 430 models due to potential jamming of the internal components of the Emergency Locking Retractor as a result of the front seatbelts being extended quickly with strong force. This could prevent the seatbelt from retracting any further (PRA 2006/8448).
• In April 2006, a recall was issued for Lexus S190 GS vehicles due to insufficient heating agents within the curtain and knee airbags. As a result, expansion of the gas in the inflator may be insufficient to properly inflate the airbag when the airbag system was activated during a collision (PRA 2006/8423).
• In November 2007, a recall was issued for Lexus S190 GS 300 models manufactured from 21 December 2004 to 27 October 2005 due to possible high stress areas in the two fuel pipes located on the engine’s fuel delivery manifold. As a result of high fuel pressure pulsations and naturally corrosive agents in the fuel, a fractured could form in the pipes over time (PRA 2007/9683).
• In October 2010, a recall was issued for Lexus S190 GS 300 models manufactured from 21 December 2004 to 6 December 2005 due to the brake fluid containing insufficient polymers, causing the brake master cylinder rear rubber seal to become dry and curl during brake application. This could result in brake fluid leaking from the rear of the brake master cylinder, causing a low level of brake fluid and the warning light to illuminate. If operated in this condition, brake pedal feel could change and braking performance could degrade over time. Owners were to contact their dealership for inspection and replacement of the rear rubber cup of the brake master cylinder. The recalled vehicles had VINs in the range JTH BH96S# 05000016 to 05028558 (PRA 2010/12082).
• In October 2010, a recall was issued for Lexus S190 GS 300 models produced from 28 September 2004 to 28 February 2006 due to a condition in which the engine may not start or stall due to a loss of fuel pressure. This was due to the fuel pump wire harness insulation having insufficient flexibility which; over time, the internal connector may move and have insufficient electrical contact (PRA 2010/12077). The recalled vehicles had VINs in the following ranges:
  • JTH BH96S# 00001011 to 00001019; and, JTH BH96S# 05000012 to 05035649.
• In July 2010, a recall was issued for Lexus GS 450h and GS 460 models produced from February 2007 to August 2008 due to the possibility that the valve springs may crack and break from excessive stress (PRA 2010/11780). The recalled vehicles had VINs in the following ranges –
  • GS 450h: JTH BC96S# 05000127 to JTH BC96S# 05016528; and,
  • GS 460: JTH BL96S# 05000021 to JTH BL96S# 05002885.
• In October 2012, a recall was issued for Lexus S190 GS vehicles produced from January 2005 to October 2011 (inclusive) that were fitted with a Genuine Lexus Detachable Towing Hitch (part number PZ408-S1552-00 – this part number was affixed on a bracket mounted next to the tow hitch housing). In some cases, the tow hitch may develop a crack when under severe mechanical stress and fracture – this may pose a hazard to drivers and other road users (PRA 2012/13318).
• In October 2014, a recall was issued for Lexus S190 GS 300, GS 450h and GS 460 vehicles. In these vehicles, the sealing property of the gasket between the fuel pressure sensor and the fuel delivery pipe could degrade over time – if this occurred, fuel may leak and pose a fire hazard. If the owner detected a smell of fuel either inside or outside the vehicle, Lexus recommended that the driver immediately stop driving the vehicle and contact their nearest Lexus Dealer for diagnosis and repair (PRA 2014/14385). The recalled vehicles had the following VINs and production dates –
  • GS 300: JTH BH96S # 05055711 to JTH BH96S # 05068477 (produced from 3 September 2007 to 16 June 2010);
  • GS 450h: JTH BC96S # 05000011 to JTH BC96S # 05022832 (produced from 28 September 2005 to 22 June 2010); and,
  • GS 460: JTH BL96S # 05001715 to JTH BL96S # 05004224 (produced from 24 December 2007 to 15 June 2010).
• In April 2016, a recall was issued for Lexus S190 GS 300 vehicles that were manufactured from December 2004 to August 2007. Due to improper tightening of the fuel pressure sensor, the sealing performance of the fuel pressure sensor to the delivery pipe could degrade over time. If this occurred, fuel could leak past the gasket; in the presence of an ignition source, there would be a risk of a fire. The recalled Lexus S190 GS 300 vehicles had VINs in the range JTH BH96S # 05000012 to JTH BH96S # 05055540 (PRA 2016/15329).

Lexus S190 GS 300: carbon deposits, DTC P030# & oil consumption

For the Lexus GS 300’s 3GR-FSE engine, there have been reports of carbon deposits (or build-up) on the intake valves. In these direct injection engines, carbon deposits may accumulate on the stem and throat of the intake valve due to:

1. the vaporisation of oil which is not trapped by the oil separator; or
2. unburned fuel and exhaust gases that escape past the piston rings and enter the crankcase (‘blow-by’).

Since direct injection engines do not spray fuel on the backside of the intake valves, the detergent properties of the fuel cannot remove the carbon build up (as occurs in port injected engines).

In November 2012, Lexus issued Service Bulletin L-SB-0125-12 for 2006 model year Lexus S190 GS 300 vehicles exhibiting one or more of the following:

• Illumination of the Malfunction Indicator Lamp (MIL) with Diagnostic Trouble Code (DTC) P0300, P0301, P0302, P0303, P0304, P0305 and/or P0306;
• Rough running after coming to rest with the engine at operating temperature;
• Rough running with engine misfires after a cold start; and,
• Engine oil consumption exceeded 1 litre every 2000 km.

To fix,

• The engine was to be removed from the vehicle;
• The engine block, cylinder head and valves were to be cleaned and decarbonised;
• The cylinder bores were to be inspected for crosshatch and/or vertical scratches. If vertical scratches were present and could be felt with a fingernail, or if the crosshatch was not visible, the short block assembly was to be replaced;
• The engine was to be reassembled with new pistons, piston rings, valve stem seals, valve springs, valve lash adjusters and valve spring retainers; and,
• The engine was to be reinstalled in the vehicle.

According to the service bulletin, new pistons, piston rings, valve springs, valve lash adjusters and valve spring retainers were introduced on 2006 model year Lexus GS 300 vehicles with VINs after JTHBH96S#65027366, so these vehicles are not supposed to experience the same carbon build-up problems.

Lexus S190 GS 300: misfire codes (DTC P030#)

In September 2008, Lexus issued Service Bulletin L-SB-0087-08 Rev1 for 2006 model year Lexus GS 300 vehicles with VINs preceding JTHBH96S#65027366. In these vehicles, the Malfunction Indicator Lamp (MIL) may illuminate with one or more of the following Diagnostic Trouble Codes (DTCs):

• P0300: random misfire detected;
• P0301: cylinder 1 misfire detected;
• P0302: cylinder 2 misfire detected;
• P0303: cylinder 3 misfire detected;
• P0304: cylinder 4 misfire detected;
• P0305: cylinder 5 misfire detected; and,
• P0306: cylinder 6 misfire detected.

The valve springs were improved to prevent this condition from recurring. For affected GS 300 vehicles, the valves and valve spring retainers were to be replaced.

Lexus S190 GS 300: MIL and DTCs

In August 2009, Lexus issued Service Bulletin L-SB-0092-09 for 2006 model year Lexus GS 300 vehicles. In these vehicles, the Malfunction Indicator Light (MIL) may illuminate and at least one of the following Diagnostic Trouble Codes (DTCs) may be issued:

• P0172: system too rich, bank 1;
• P0175: system too rich, bank 2;
• P2196: oxygen A/F sensor signal stuck rich, bank 1 sensor 1;
• P2198: oxygen A/F sensor signal stuck rich, bank 2 sensor 1;
• P0138: oxygen sensor circuit high voltage, bank 1 sensor 2;
• P0158: oxygen sensor circuit high voltage, bank 2 sensor 2;
• P0037: oxygen sensor heater control circuit low, bank 1 sensor 2; and,
• P0057: oxygen sensor heater control circuit low, bank 2 sensor 2.

Depending on the diagnosis, three repair procedures were offered. For more information, please refer to the service bulletin.

Lexus S190 GS 350 and GS 450h: engine won’t start or stalls on start-up

In November 2008, Lexus issued Service Bulletin L-SB-0161-08 Rev1 for 2007-08 Lexus GS 350 and GS 450h vehicles. Intermittently, the engine may not start or may start and immediately stall after the ‘Push Start’ button is pressed. A new ‘Push Start’ switch was introduced to fix this problem.

Lexus S190 GS 300, 430 and 450h: instrument panel rattle

In July 2008, Lexus issued Service Bulletin L-SB-0040-08 for 2006-07 model year GS 300, GS 350, GS 430 and GS 450h vehicles. In these vehicles, rattling noises may be emitted from the front of the instrument panel at the base of the windscreen. To fix,

• The instrument panel sub-assembly was to be removed;
• The instrument panel attachment clips were to be removed;
• The four instrument panel clips and single centre instrument panel stay were to be removed and replaced;
• Felt was to be applied to the defroster nozzle lip; and,
• Foam was to be applied to the instrument pad HVAC duct.

Lexus L10 GS 350: difficulty closing boot

In August 2012, Lexus issued Service Bulletin L-SB-0065-12 for 2013 model year Lexus L10 GS 350 vehicles with VINs preceding JTHBE1BL#D5008228. In these vehicles, it may be difficult to close the boot. To fix, the four rubber cushions located in the lower portion of the boot lid were to be replaced.

2013-14 Lexus L10 GS 350 and GS 450h: won’t start and steering lock engaged

In May 2014, Lexus issued Tech Tip L-TT-0113-13 for 2013-14 model year Lexus GS 350 and GS 450h vehicles for the following symptoms:

• The vehicle would not start or ‘ready-20’; and,
• The steering wheel lock would be engaged such that the steering wheel could only be turned slightly.

If the driver tried to start or ‘ready-20’ the vehicle while there was tension on the steering lock actuator, it would not be able to fully disengage when the ‘Engine Start Stop’ or ‘Power’ switch was depressed. These circumstances would cause the vehicle message centre to display the ‘Steering Lock Engaged’ error message and the vehicle would fail to start or ‘ready-20’.

To overcome this problem, the driver was to move the steering wheel from side-to-side to relax tension on the steering lock actuator. Once the steering lock actuator was free to disengage, the driver would be able to start or ‘ready-20’ the vehicle the vehicle.

ZF Transmission

The six-speed ZF automatic transmissions used an external heat exchanger to cool the transmission. However, the lines within the heat exchanger could deteriorate over time, allowing coolant and transmission oil to mix. If this occurred, the fluid in the coolant reservoir would appear milky (hence the term ‘milkshake’) and, within the transmission, the friction linings would be pulled from their steel backings and the mechatronic control unit would be damaged. To fix, the transmission would have to be rebuilt and the mechatronic control unit replaced.

To prevent contamination of the transmission fluid with coolant, a common modification was to fit an external air/oil cooler kit to bypass the heat exchanger. In fitting these, however, it was important that the transmission fluid be filled to the correct level as the ZF transmission was sensitive to fluid levels and would enter ‘limp home’ mode if not within tolerances. Another modification was to replace the OEM heat exchanger and hoses/lines to the transmission with a more robust after-market product. Please note, however, that Ford Australia considered any modifications to the heat exchanger to void the warranty.

Suspension

• Knocking noises from the rear suspension when driving over bumps may indicate that the upper shock bushes require replacement.

Battery voltage

Ford’s FG range introduced a new CAN Bus which can result in error messages and faults (such as the air conditioning not working, see below) if battery voltage drops below 9.6 volts during start up. While the original battery fitted by Ford was rated as 520 CCA, it is recommended that higher rated batteries be fitted.

Air conditioning not working

• The FG Falcon range had a different air conditioning than its BA/BF predecessors and poor performance could be due to a defective HIM module (most common for late 2009 to early 2010 models). For models with climate control, a faulty ambient temperature sensor – positioned on the left wing mirror – could also be the cause. A software upgrade was subsequently introduced which kept the compressor engaged for longer.
• In March 2011, the conditioning system was revised with a new HIM module, evaporator, condensor, compressor and pipework, though it cannot be retrofitted to earlier models.
• If the battery voltage drops below 9.6 volts during start up, the air conditioning compressor won’t operate (such that air conditioning will not work). If the battery has recently been disconnected or gone flat, the air conditioning must be reset by letting the motor idle with the air conditioning switched on for at least a minute.

Miami V8 engine: oil consumption

For Ford’s 5.0-litre supercharged Miami V8 engine, owners are recommended to check the oil level every 1,000 kilometres when running in and every 2,000 kilometres thereafter since the engine does consume some oil when new. In the USA, Ford considers oil consumption for the supercharged V8 engine of one quart per 1000 miles (around 600 ml per 1000 kilometres) to be acceptable.
