“I purchased my 2007 mercedes benz ML350 on 10/11/14 on 10/24/14 I began having problems with what seemed to the shifting of gears. When trying to slowly excel from either a complete stop or a slow crawl it seems as though the car would not move, it was having a problem automatically shifting from 1st to 2nd gear, and back down from 3rd to 2nd. This has happened several times and has occurred while in traffic endangering my and my families lives. After speaking to a mechanic, he has stated that this seems to be continual problem with this vehicle and should be made part of a recall! …”
