2006 Mercedes-Benz ML500 Problems
RepairPal has identified the most common problems with the 2006 Mercedes-Benz ML500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. A new door latch will need to be installed.
An engine oil leak may develop from the oil level sensor. Replacement of the leaking sensor will commonly correct this concern.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
A problem with the ball joints can cause a creaking noise. There is an updated part to remedy this problem.
Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.
After a heavy rain storm, the drains for the heating, ventilation and AC (HVAC) system intake can be plugged with leaves and other debris, causing a dead battery. Water fills the intake cavity and overflows into the vehicle, directly onto the blower motor and its regulator. This causes the regulator to short out and the blower motor will continue to run, despite the key being off and removed from the vehicle. Usually the carpet at the right front passenger floor will be wet too. If the carpet is saturated, the passenger seat may need to be removed to dry out the battery storage area before water or moisture reaches the relay and fuse holders. To prevent this, do not let leaves and twigs accumulate at base of windshield. If there are leaves or debris below the wiper blades, clean the area.
An engine Oil leak may develop from the PCV vent housing on the valve cover and/or the inspection plate on the front of the engine.
The door storage pocket can become unglued and fall into the door.
