The affected vehicles are equipped with a high voltage onboard charger that may not have been built to specification, and as a result, the charging function for an external charging cable might not function and the onboard charger may incorrectly detect a charging cable, even while the vehicle is being driven.
If the charging cable is incorrectly detected and the vehicle is stopped or moving at a very slow speed, the vehicle may unexpectedly shift to park, increasing the risk of a crash.
MBUSA will notify owners, and dealers will replace the onboard charger, free of charge.
The recall began on January 27, 2016.
