Mercedes Benz ML350 owners have reported 1 problem related to steering idler arm (under the steering category). The most recently reported issues are listed below.
Serpentine belt system. While driving on road at the highway speed, one of the idler pulleys locked up due to the failed bearing, leading to damaging/braking serpentine belt. That led to loss of steering (loss of power steering) and overheating the engine. Created a very danger situation and left my family stranded many miles away from home. Very costly towing service and repair.
