2003 Mercedes-Benz ML350 Problems
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 engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
The heater blower motor can become abnormally noisy. Replacement of the blower motor is commonly necessary to correct this concern.
The power steering return hose may leak at the radiator cooler fitting. If the clamp is not properly tightened, the hose can blow off, causing increased steering effort and a mess under the hood.
The door storage pocket can become unglued and fall into the door.
The power window switch may fail and the windows will not raise. The main switch at the front center console is commonly at fault. A failed switch will require replacement.
The insulation at the sunroof and on the inside of each door window glass can peel off. The loose insulation will then scrape the sunroof or window glass as it is operated. Replacement of the damaged insulation will be necessary to correct this concern.
The covering for the center console can bubble and discolor. Replacement of the affected part is most commonly only way to repair this concern.
Motor mounts commonly fail, causing engine vibrations to be transferred to the body. Failed motor mounts should be replaced in order to prevent damage to the transmission mount.
As the spark plug wires age and are exposed to heat cycling, they start to develop micro cracks in the insulation around the resistors, which causes misfires and poor fuel economy.
Arms for the sunroof wind deflector break; if the broken pieces are not removed, they can jam the sunroof.
