2003 Mercedes-Benz ML350 Problems

"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.

AC System Leaks/Bad Temperature Sensors May Cause Poor Cooling

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.

Camshaft Adjuster Solenoid Failure

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Very expensive car to own. All repairs cost double what you would expect to pay. Brakes go quickly (every 10k-15k miles). My AC compressor required replacement at 75k. Ridiculous engineering jacks up repair cost. For example, my REAR seatbelt sensor went out, which meant that the FRONT passenger airbag would not function. Tell me why those are tied together? Another example: a broken w...
