Two problems related to engine belts and pulleys have been reported for the 2007 Mercedes Benz ML350. 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.
Engine light came on . Take to repair shop,crank sensor bad,changed crank sensor, light came on back,O2 sensor bad, changed O2 sensor,light came back on,finally said worn sprackett in engine sending false reading. Steering pump went bad at 59000. Ac pump pulley broke off at 54000 miles. Ac/heat comes on by itself, even when vehicle is turn off.
