Engine may not restart after automatic stop
Reported January 8, 2016Model years 2012–2015DVSA recall R/2015/2471,126 vehicles affected
Excess wiring harness length may cause a faulty camshaft signal, preventing the engine from restarting after an automatic stop. It can be restarted manually using the transmission selector and ignition key or start button. The wiring harness will be reworked.
Official DVSA recall text
Component
STOP START ENGINE MAY NOT RESTART
Defect
The excess length of the wiring harness to the engine control unit could result in a faulty camshaft signal. This faulty camshaft signal may lead to an unintentional cancellation of the automatic starting procedure after automatic engine stop of the automatic start/stop system. In the event of a faulty camshaft signal the engine would not restart as expected following the stop procedure but can be manually restarted immediately by engaging the transmission selector lever position ï¿½Nï¿½ or ï¿½Dï¿½ and by operating the ignition key or the start button (with keyless go). Depending on the traffic situation however an increased accident hazard could result.
Remedy
Recall the vehicles that are likely to be affected and rework the wiring harness to the engine control unit on the affected vehicles as a precautionary measure.
Engine may idle erratically or shut down
Reported January 8, 2016Model years 2013–2015DVSA recall R/2015/232660 vehicles affected

Transmission may engage park below 5 km/h
Reported January 5, 2016Model years 2015DVSA recall R/2015/24826 vehicles affected
A high-voltage battery charger may incorrectly detect a charging cable and request Park. Below 5 km/h, the park pawl may engage and prevent the vehicle from moving, increasing incident risk. Replace the charger.
Official DVSA recall text
Component
TRANSMISSION MAY LOCK AT LOW SPEED
Defect
The high-voltage battery charger may not have been produced to specification which could lead to an incorrect detection of an external charging cable. This in turn can lead the request for ï¿½Pï¿½ to be activated. If the speed is less than 5 km/h the transmission would activate the park pawl function which will prevent the vehicle from driving further and could increase the risk of an incident.
Remedy
Recall the vehicles that are likely to be affected and replace the high-voltage charger on the affected vehicles.
Onboard charger may trigger unexpected shift to park
Reported November 24, 2015Model years 2015NHTSA campaign 15V79600052 vehicles affected
