2009 Mercedes-Benz ML350 Problems
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 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.

Does anyone know a less expensive shop?
From last week all of a sudden radio stays on (I think ignition also stays on)after shutting engine. I am using keyless on/off button to turn on or off car. If I use key then it shuts off.
We are thinking about purchasing this 2009 MB ML 350, with 81,000 miles. We believe it is due for the B service. Are these cars truly dependable after 100,000 miles?! Good purchase? Feedback, please!
