An owner's complaint to NHTSA about the air bags, Sep 2017
“I received an Stop Drive Order form Mercedes Benz USA more that a week ago and I stopped driving my vehicle. I contacted the closest authorized MB dealer Union, NJ and they have not provided a loaner car and have not yet fixed the issue. They say they have so many calls and cannot do anything for me despite the fact I waited so long.”
