2005 Mercedes-Benz ML350 Problems

Rear Tailgate Latches May Hang up and Cause Battery Drain

The tailgate latch may stick causing a drain on the battery while the vehicle is parked.

"No Start" Due to Drive Authorization's Failure to Recongnize Keys

A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.

Electrical Switches in Door Latches May Fail
