  • Recall R/2017/124 [UK]: Faulty control unit may cause vehicle to perform outside specification

  • Recall R/2015/247 [UK]: Stop start engine may not restart
    The excess length of the wiring harness to the engine control unit could result in a faulty camshaft signal.

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 ?N? Or ?D? 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.
    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.

    On certain vehicles originally sold or currently registered in areas of heavy road salt usage during winter months (quebec, new brunswick, nova scotia, prince edward island, and newfoundland & labrador), the bolts that attach the electric power steering assist motor to the steering gear housing may corrode and break.

Correction: dealers will replace the mounting bolts and apply a corrosion protection coating to the gear housing and bolts. If the bolts bolt cannot be removed, a replacement steering gear will be installed.
