I have a 2013 ML 350. Over the last month, occasionally after I put the car in reverse, stop, and then try to put it in drive, it won't go into drive. Once, I was in drive and tried to put the SUV in neutral and it would not go, it only went into park. When this happens, I can turn vehicle off and back on and then it works fine. The dealer said it might be the unit in the steering column but they said it would usually effect blinkers and other things if that were the case and it does not with my vehicle. Brake lights seem to work fine I assume it is not the brake switch. Any advice you can offer would be greatly appreciated.
