The affected S550 Plug-in Hybrid cars were built from April 24, 2015 to June 12, 2015.
“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,” NHTSA said in its recall summary. “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.”
Mercedes-Benz dealers will replace the onboard charger. The recall is expected to begin in early January. Owners can contact Mercedes-Benz customer service at 1-800-367-6372.
