2004 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

Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. The affected door latch should be replaced to correct this concern.

I don't know what other vehicle you can drive in Texas for 36,000 miles without a water pump, and I don't encourage ANYONE to try it, but I can verify it's been done. About 55 miles each way, twice a day. And before that, I broke the radiator on a beach. 20 or so miles, without damage then and it was about 95 degrees on that day.
