2004 Mercedes-Benz ML350 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2004 Mercedes-Benz ML350

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump.

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

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. One last thing...people complain about dealer maintenance, an...

I really like the steering on this vehicle... makes good turns vs. other SUV's I've driven. Mine now has 80,000 miles on it and just replaced a headlight at an independent garage - only $14 ! I'm sure the Mercedes dealer would have charged far more. Probably need a new water pump very soon... but other than that, I've had no problems at all with this vehicle. I enjoy the smooth ride, too...

Overall nice car, I like the handling.
