• Engine#2016289June 8, 2016

  178 units affected

  On certain vehicles, the Engine Control Module (ECM) may develop an internal electrical short circuit that could blow a fuse in the ECM's electrical supply circuit. This could cause the engine to stall without warning and prevent the vehicle from being restarted. Engine stalling without warning would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the ECM.
