I purchased a used mercedes from BMW of mobile. While driving the car it loses power. I was on the interstate and it loss power. I almost had a panic attack because the car was slowing down. I had no idea what was going on. I had to make my way to the right lane to get off the road. Mind you cars were driving 70 and 80 mph. They could have rammed into the back of my car not knowing my car was slowing down. I could have been killed driving this defective vehicle!!! I informed BMW and their technician said it it was the battery and a starter. I paid $600 for the repair. They were wrong the car still loses power. I had to beg and plead with them to have mercedes of mobile diagnose the car. They said they would pay for the diagnosis but not the repairs. If I traded the car back to them they would deduct the repairs from the car. The other options were to let it go back to the finance company or take it to another dealership and not tell them what going on with the car. They paid mercedes of mobile to diagnosis it and they immediately stated the issue. I went to BMW to ask for a refund and repair but they refuse to do any about the car losing power. I would not recommend this dealership to anyone. They should have had this car checked out thoroughly at mercedes if they did not have the appropriate knowledge of the car.
Vehicle becomes stuck in gear while driving down the road. Will not shift, sometimes you don't have enough power to move quickly. For example vehicle was stuck in 6th gear after leaving the highway. I could not accelerate to move the car. I had to shut the car off to reset the computer to get the car out of 6th gear. This has happened at least 10 times over the past 3 month period. Many other owners of this car have experienced the same transmission failure and that is very dangerous because the car lose power when it is stuck in a gear. The only way to fix the problem is to shut off the car and restart it. Mercedes benz should be held responsible for this issue.

I was driving my S550 and came to a red light. I stopped at the light and when it turned green, I took my foot off the brakes and pressed the accelerator, but there was to response to pressing the accelerator. The car rpms were increasing but the vehicle was crawling at less than 5mph. This led to me pulling over and parking the vehicle and turning it off. I waited 5 minutes and then restarted it and it began to work normally. The second time this happened was while making a left turn, I pressed the gas pedal and there was no response and the car was reving but traveling less than 5 mph with oncoming traffic having to stop short to prevent crashing into me while I was making the left turn. This was again resolved with me parking the vehicle, turning it off and then restarting it. After the second time this occurred out of no where I decided its a very dangerous safety issue.
Vehicle is stopped at traffic light with driver's foot on brake. Engine revs up for a moment and vehicle lurches forward. Happened at two stops at lights within a few minutes.
