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.

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.

Steering Rack Prone to Leaks

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.

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...
