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: Toyota ZN6 86
2012-15 Toyota ZN6 86: electric power steering may be lost
In August 2016, a recall was issued for Toyota ZN6 86 vehicles that were manufactured from April 2012 to March 2015. Due to improper harness layout and terminal wear, these vehicles may experience a loss of electric power steering assistance. While the vehicle could still be driven without power steering assistance, the increased steering effort required – particularly at low speeds – could increase the risk of a collision (PRA 2016/15586). The recalled Toyota ZN6 86 vehicles had VINs in the following ranges:
- JF1 ZN6K72 DG002006 to JF1 ZN6K72 DG015716;
- JF1 ZN6K72 EG018002 to JF1 ZN6K72 EG023149;
- JF1 ZN6K72 FG025022 to JF1 ZN6K72 FG029639;
- JF1 ZN6K81 DG002013 to JF1 ZN6K81 DG015715;
- JF1 ZN6K81 EG018001 to JF1 ZN6K81 EG023148; and,
- JF1 ZN6K81 FG025003 to JF1 ZN6K81 FG029637.
2012-13 Toyota 86: engine valve springs could break
In November 2018, recall campaign LGG85 was issued for Toyota 86 vehicles that were manufactured from 9 April 2012 to 8 July 2013. In these vehicles, the engine valve springs could fracture if the performance load exceeded the fatigue strength of the valve springs. If a valve spring were to be fracture while the vehicle was being driven, the vehicle would experience a sudden loss of power and the engine may not restart. For the VINs of the recalled Toyota 86 vehicles, please see PRA 2018/17140.

2012 Toyota 86: VVT-i Response and VVT-i System Failure
In August 2012, Subaru issued Service Bulletin 02-132-12 for Subaru BRZ vehicles and this bulletin is also applicable to the Toyota 86. According to the bulletin, these vehicles may exhibit the following diagnostic trouble codes (DTCs):
- P000A, P00B, P00C and P00D (‘AVCS Slow Response’); and,
- P0011, P0014, P0017, P0018, P0019, P0021 and P0024 (‘AVCS System Failure’).
Depending on the diagnosis, rectification of these symptoms could involve:
- Replacing the oil control valve (OCV);
- Replacing the cam sprocket assembly – it is understood that its oil passages could become clogged with debris; or,
- Replacing the Engine Control Module (ECM).
2012 Toyota 86: malfunction indicator light and DTCs P0017 or P0019
In January 2013, Toyota USA issued Technical Service Bulletin S-SB-0032-12 Rev 1 for 2012 Toyota 86/Scion FR-S vehicles that had VINs preceding JF1ZNAA1#D#710670. In these vehicles, the malfunction indicator light (MIL) may illuminate and one of the following diagnostic trouble codes (DTCs) may be logged in the powertrain control module (PCM):
- P0017; or
- P0019 (‘Cam Sensor Correlation’).
The PCM logic was revised to address this condition and, to fix, the PCM was to be replaced or re-programmed. The information in this service bulletin corresponded to Service Bulletin 02-137-12 which was issued for the Subaru BRZ.
2012 Toyota 86: DTC P1235 (High-Pressure Fuel Pump Circuit)
In December 2012, Toyota issued Service Bulletin S-SB-0036-12 for Toyota 86/Scion FR-S vehicles that had VINs preceding JF1ZNAA1#D#710670; from Subaru’s Service Bulletin 02-138-12, it is understood that this corresponded to vehicles manufactured prior to 12 September 2012. For these vehicles,
- The Malfunction Indicator Light (MIL) may illuminate; and,
- Diagnostic Trouble Code (DTC) P1235 (‘High-Pressure Fuel Pump Abnormal’) may be logged in the engine control module (ECM).
To fix, the powertrain control module (PCM) was to be re-programmed.
2012-13 Toyota 86: tapping noise from left cylinder head
In September 2014, Subaru issued Service Bulletin 02-151-14R for 2012-13 Subaru BRZ vehicles, and this bulletin is also applicable to the Toyota 86. The service bulletin announced the availability of revised valve train components that were developed to reduce a tapping noise – sometimes described as a ‘sewing machine’ type noise – that may be emitted from the left-hand side of the engine when the engine was warm. The changes included:
- A design change to the roller portion of the valve rockers;
- Re-profiled intake and exhaust camshafts;
- 1.65 mm longer intake valve stems (increased from 103.3 mm to 104.96 mm); and,
- 2.47 mm longer exhaust valve stems (increased from 95.1 mm to 97.57 mm).
To rectify the tapping from the left cylinder head, the following parts had to be replaced:
- The intake and exhaust camshafts;
- The four intake and exhaust valves; and,
- All eight rockers and pivots.
2012-13 Toyota 86: hard start, rough idle, camshaft sensor or misfire DTCs
In May 2014, Toyota USA issued Technical Service Bulletin S-SB-0033-14 for 2012-13 Toyota 86/Scion FR-S vehicles that had VINs preceding JF1ZNAA1#D#721474. These vehicles may exhibit diagnostic trouble codes (DTCs) – such as P0340, P0341, P0345, P0346, P0365, P0366, P0390, P0391, P0301, P0302, P0303 and P0304 – which related to:
- The intake and/or exhaust camshaft position sensor; and/or,
- Engine misfires.
Furthermore, the vehicle may experience a rough idle or extended cranking when attempting to start to vehicle.
According to the bulletin, these DTCs were attributable to camshaft position sensor clearance being out of specification; the DTCs would indicate whether it was the intake camshaft position sensor (P0340, P0341, P0345 or P0346) or exhaust camshaft position sensor (P0365, P0366, P0390 or P0391). To fix, the camshaft position sensor was to be re-installed with a shim to correct sensor clearance.
The information in this service bulletin corresponded to Service Bulletin 11-130-13R which was issued for the Subaru BRZ.
2012-13 Toyota 86: intermittent RPM drop when idling
In December 2013, Toyota USA issued Technical Service Bulletin S-SB-0040-13 for 2012-13 Toyota 86/Scion FR-S vehicles that had VINs preceding –
- For automatic models, JF1ZNAA1#E8703673; and,
- For manual models, JF1ZNAA1#E9703671.
From the corresponding Service Bulletin 11-136-14 issued by Subaru, it is understood that these vehicles were produced prior to 27 September 2013.
When the vehicle was idling and the air conditioning was switched off, these vehicles may exhibit an intermittent drop in engine speed. To fix, the powertrain control module (PCM) was to be re-programmed with an updated calibration.
2012-13 Toyota 86: abnormal chirp or squeak from high pressure fuel pump
In October 2013, Toyota USA issued Technical Service Bulletin S-SB-0023-12 Rev 2 for 2012-13 Toyota 86/Scion FR-S vehicles that had VINs preceding JF1ZNAA1#E#702951. When the engine was fully warmed up and idling, these vehicles may exhibit a high pitch chirp or squeak noise from the high pressure fuel pump assembly.
According to Subaru’s Technical Service Bulletin 09-54-12R, this noise was due to internal components of the pump in combination with fuel temperatures or fuel formulations causing aeration of the fuel within the body of the pump. According to the bulletin, however, this was not detrimental to the fuel system of the engine. From mid-September 2013, the following production changes were made to reduce the occurrence of the sound, including:
- A change to the internal fuel passage;
- A change to the shape of the plunger stopper; and,
- A change to the pulsation dampener assembly.
To fix, the high pressure fuel pump assembly was to be replaced.
