The engine control unit and transmission control unit software may have compatibility conflicts and cause the engine to shut-down while the driver brakes to a stop, or accelerates following an ECO start.
If the engine shuts down, there is increased the risk of a crash.
What to do
MBUSA will notify owners, and dealers will reprogram the engine and transmission control unit software, free of charge. The recall is expected to begin in September 2017.
Owners may contact MBUSA customer service at 1-877-496-3691.
