Automatic transmission malfunction may affect vehicle emissions
Incorrect software in the engine control module can lead to malfunctions of the automatic transmission that could affect vehicle emissions. There may be no communication of the defect to the driver (MIL) and the defect would not be visible to a scanning diagnostic tool during servicing. There is no known concern affecting the safety of the automatic transmission in relation to this campaign but vehicle emissions may not be to the manufacturers specification.
Fix: Recall the vehicles that are likely to be affected and reprogram the Electronic Control Module with latest level software.

Oil may leak engine may stall
Due to insufficient sealing of the timing chain tensioner gasket the timing chain tensioner may loosen and an oil leak may occur from the engine. If t the vehicle continues to be driven engine oil could leak onto the road and the engine might stall due to low oil level. In an extreme case and in the presence of an ignition source there may be an increased risk of a fire.
Fix: On affected vehicles replace the timing chain tensioner gasket with new.

Vehicle may cut out
It has been identified that due to a software error the traction motor inverter may incorrectly diagnose communication between the inverter and the transmission control module (TCM). This can cause the inverter system to suddenly shut down. If the vehicle is being driven in Electric Vehicle (EV i.e. engine off) the power to the electric motor may be cut resulting in the vehicle coming to a sudden stop.
Fix: Recall all affected vehicles to install new software for the traction motor inverter control module.

Unintended acceleration
It has been identified that under certain circumstances the throttle position sensor may send an error signal to the Engine Control Module (ECM). As a result the ECM may not operate as intended and the vehicle may accelerate gradually without the driver operating the throttle pedal. However this acceleration can be overridden by application of the brakes.
Fix: Recall all affected vehicles to install new software of the ECM.

Under extreme circumstances transmission may detach
It has been identified that due to an issue during the casting process of the front of the transmission casing the casting may become cracked during the release phase of the operation. If the vehicle is driven at high speed in this condition the crack can grow and cause a vibration. In an extreme case the transmission may detach from the vehicle.
Fix: Recall all affected vehicles to inspect the transmission casing for cracks and replace any transmission are found to be cracked.
