1 safety recall, most serious first
1. Latches / locks
What's wrong, in plain English: Doors, hood or trunk may open unexpectedly. Please refer to MBUSA's recall report for specific model information. The micro-switch in the driver's door lock may corrode and fail to detect an open door, preventing the electronic parking brake or "Auto-Park" feature from engaging automatically.
