Most reported Mercedes-Benz ML55 AMG problems
The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.
The door storage pocket can become unglued and fall into the door.
Release cables for the rear seat (second row of seats) tend to stretch or break requiring replacement.
The covering for the center console can bubble and discolor. Replacement of the affected part is most commonly only way to repair this concern.
An exhaust leak may develop due to cracked welds on the front catalytic converter. Replacement of the catalyst is recommended; re-welding of the catalyst is discouraged because it is an emissions device.
A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.
The heater blower motor can become abnormally noisy. Replacement of the blower motor is commonly necessary to correct this concern.
The rear corner panels on either side of the tailgate (black plastic) can crack or break. They should be cut off and the adhesive removed before new panels are glued on.
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.
These vehicles have torsion bar-type springs for the front suspension. If the vehicle appears to be lower on one side (in front), the hard plastic insulator for the torsion bar may have cracked and split. There may also be a squeaking noise (when driving over bumps) from below the front seats if this insulator has broken.
Due to slipping clutches in the transfer case, a shudder or rumbling from the center of the vehicle may occur, especially when turning at slow speeds. If the clutches are not too badly worn, changing the fluid will fix this problem. Otherwise, the transfer case will need to be disassembled to change the clutches.
Leaking at top driver side of the tank at the hose clamp/hose location. Possibly crack/broken plastic hose connection.
