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.
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.
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.

My COMAND system is not be able to turn on. Not be able to use the radio, navi, phone, CD player and everything on that unit. I have waited for few days, and seems it is totally dead. Is there anyone knows what is the price range to get the COMAND replaced in the dealership?
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.
2009 Mercedes-Benz ML350 Recalls
Due to a faulty seal around the tail light assembly, water may enter the rear compartment containing the spare tire. The water could damage the lift gate control module, causing it to fail. The failed module could overheat, increasing the risk of a fire. Dealers will update the tail light seals and relocate the lift gate control module. This recall is expected to begin during April of 2009. The Mercedes recall number is 2009030003.
