2007 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.

2007 Mercedes-Benz ML350 Reviews

Have 30,000 miles on my ML and no problems. Only factory recommended service. Relatively low service cost if you shop around. I use a quality independent and cost is half of dealer service cost. Brake pads are ok at 30k, but need replacement in next 6 months. Rotors ok till 50-60k. I love that the ML gives me the handling of a lux sport sedan, but the utility of an suv. Great all around vehicle.
