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.

Mercedes-Benz ML350 Recalls
The Diesel fuel filter may leak from the area around the heating component. Fuel may leak onto the roadway, increasing the risk of a crash. A fuel leak always increases the risk of a fire. Dealers will replace the Diesel fuel filter to correct this concern.
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.
Mercedes–Benz is recalling certain 2008 GL-Class, M-Class, and R-Class vehicles for a possible defect in the driving pin used to control power steering oil pressure. If the pin breaks during normal vehicle turning, the steering assist will no longer operate, causing difficulty operating the steering wheel. Dealers will replace the steering gear in affected vehicles.
Mercedes-Benz ML350 Reviews
I was rather surprised to find this site AFTER I purchased a used 2006 ML350. AND I wish I had never bothered. I was excited when I realized that I, single mother of three, would be able to afford the luxury of a Mercedes!! Not all that it's cracked up to be. Brakes (pads and rotors) always need replacing, which is odd because I do more distance driving than city (not alot of brake use). P...

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.
