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.

Power steering began making low pitched humming noise, which led me to discover a power steering fluid leak. Upon doing research online, and talking to Mercedes techs, I've found this to be a very common problem with these vehicles. It can and has led to power steering / rack failure and is a major safety hazard.

At approximately 65,556 miles, my power steering pump and reservoir as well as the front end sway bar ends and links needs to be replaced. On a high quality truck such as this 2007 ml 350 Mercedes Benz, these parts should not have worn out so quickly.

2007 Mercedes ml 350: Poor design of shift lever, located on steering column push up for reverse, push down for drive, push in for park (when doing so system makes near inaudible sound.) my wife put car in park, got out car rolled in reverse caught her leg and dragged her under, car continued to roll back and crushed her left leg, mbenz said too bad be more careful this is a design fault disaster waiting to happen. Mbenz told me all of their models are being changed to this design to keep coffee etc from spilling from console cup holders into standard console mounted shift lever. I guess mbenz needs deaths before they do something about this. This idiotic design almost got my wife killed and now she has permanent leg damage after surgery and nearly 12 months rehab.
