Brake booster got do not drive letter and contacted June 27,2024 and first week of july and said they would contact me and nothing yet.
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. I need this car on a daily basis and cannot do my work without this car. I have been calling them over and over and they disconnect the phone. This has been really frustrating. They are also saying that they are not willing to pay for any cab fee, Uber or any rental car fee. I need my car urgently and am really scared to drive this car after they sent me the STOP DRIVE Order
