Steering
2018-12-20 · campaign 2018-724
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. This could cause a loss of power steering assist. The resulting increase in steering effort could create the risk of a crash causing injury and/or damage to property. 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.
Engine
2015-10-13 · campaign 2015-464 · 369 vehicles
On certain AMG S63 models, the engine may stall due to faulty software in the Engine Control Unit (ECU). Irregular RPM at idle could lead to unintentional engine shut-down prior to a vehicle stop. If this occurs, the driver may falsely interpret the unintentional engine shut down as part of the ECO start/stop system, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will update the ECU Software.
Seats and restraints
2013-11-20 · campaign 2013-409 · 5 vehicles
On certain vehicles, the seat belt anchor fittings of the front seats might not be mounted correctly. As a result, the connection at the seat belt anchor fitting could release under heavy loading. This may affect the restraint performance of the seat belt and result in an increased risk of injury in the event of a crash. Correction: Dealers will inspect the seat belt anchor fittings.
