2004 Mercedes-Benz ML350 Problems

"No start" Due to Anti-Theft System Fault

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.

Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Air Conditioning Not Cold

AC system leaks and/or a faulty evaporator temperature sensor can cause poor AC cooling. The failed sensor can prevent the AC compressor from coming on. Leaks cause a low refrigerant level, which reduces the ability to cool.

Recently replaced purge valve, but light is back on and dealership advises to replace "charcoal cannister." If that doesn't work and still no defect code, then something with gas tank is their final suggestion. A...
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...
