2003 Mercedes-Benz ML350 Problems

Delay before crank start and no starting.

When turning the ignition key there is either a several second wait, or will have to retry.
Car has left me stranded, where key is in the on position but nothing registers and only auxiliary electrical works (stuff that works when no key in ignition.)
This problem started occurring after a service interval where half a dozen error messages required some steering parts to be replaced.

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.

Internal Component Failure May Cause Rough Shifting

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.

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...
