2005 Hyundai NF Sonata: ESC causes deceleration
In July 2005, a recall was issued for Hyundai NF Sonata vehicles due to premature activation of the electronic stability control system when driving at speeds of 40-60 km/h uphill through moderate corners, causing the vehicle to decelerate. This was due to over-sensitive operation of the electronic stability control sensor (PRA 2005/7912).

In August 2009, a recall was issued for Hyundai NF Sonata vehicles manufactured between 20 September 2006 and 25 October 2006 so that a brake lamp switch could be replaced.

Hyundai NF Sonata Diesel: engine hesitation and intake noise
In June 2008, Hyundai issued a technical bulletin for Hyundai NF Sonata vehicles with diesel engines that may experience engine hesitation and intake noise caused by the exhaust gas recirculation (EGR) system. For these vehicles, the engine control module (ECM) was to be updated with new software.
Hyundai NF Sonata Diesel: lack of power
There have been reports of Hyundai NF Sonata vehicles with diesel engines experiencing:
- Illumination of the check engine light;
- The engine not revving; or
- The engine lacking power.
These symptoms may be caused by the exhaust gas recirculation (EGR) valve sticking.
2007-09 Hyundai NF Sonata 2.4L: transmission update
In May 2010, Hyundai USA issued technical service bulletin 10-AT-007-1 for Hyundai NF Sonata vehicles that had 2.4-litre petrol engines and were manufactured from 17 December 2007 to 10 May 2009. For these vehicles, an update was issued for the ECM and TCM software to improve:
- Acceleration feel from stop or below 22 km/h; and,
- Shift quality when decelerating from around 50 km/h when the automatic transmission fluid (ATF) was cold.
Hyundai NF Sonata: automatic transmission faults
- The Sonata’s automatic transmission may not work in reverse gear due to maladjustment of the shift linkage (or transmission cable) between the gearshift selector and the transmission.
- For automatic transmissions that do not shift out of park, the key lock control module may have failed.
- Transmission fluid may leak from: 1) the front pump seal at the torque converter, requiring replacement of the pump seal; or, 2) the reduction brake piston cover, requiring replacement of two O-rings.
Hyundai NF Sonata 3.3 V6: accelerator pedal sensor
For Hyundai NF Sonata models with the 3.3-litre V6 engine, if the ‘check engine’ light illuminates and engine performance is reduced, the accelerator pedal sensor may be faulty.
Hyundai NF Sonata: other problems and faults
- Oil may leak from the transaxle at the oil seals, yet appear to be a seam leak.
- A ‘snap’ noise when shifting from reverse to drive may require an isolation washer on the front hub.
- The ‘low tyre pressure’ warning light may illuminate due to electromagnetic interference from electronic transmitters, but will usually go out when moving out of range. However, some electronic devices may also activate the warning light if they are plugged into the accessory power outlet.
- On vehicles with climate control air conditioning, the displayed temperature may be up to 5 degrees out from the actual outside temperature if the temperature sensor is faulty.
