Struts and braking system have been unstable since I purchased the car. Wiring harness leaks oil and caused ecu to intermintinli turn off and on. Also the heat control timing caused car to over heat . Eventually I replaced the ecu 2 years ago at dealer . Mercedes has parts that are not safe to be in these operating conditions with such heat causeing wiring harness to short out and dealer said that and still put new ecu saying it was oil that damaged ecu. Mechanicly didn’t make sense but now due to recall it all makes sense. Ecu was never programmed correctly causeing unsafe driving hazards .

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 revving 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.

The car stopped accelerating and then quit running. The conductor plate in the transmission failed. This is a known safety defect that mercedes-benz has ignored.

The vehicle shuts off for a second the esp and ABS lights would come on, the steering wheel of the vehicle would get stiff, the brakes get stiff the headlights and interior lights would go off, and the command center would reboot. It seems like the vehicle is experiencing a brief electrical failure. I have been complaining of this problem since I purchased the vehicle as a certified preowned vehicle. The first time I took the vehicle to the dealership the replaced the steering control module and the problem persisted. I notified them of the reoccurring problem again and the claimed the where not able to find any faults. I set up a camera in the vehicle and videotaped the problem occurring and the finally took the vehicle for an extended test drive and replaced the central gateway which did not solve the problem. I contacted mbusa customer service to notify them of the safety concerns regarding the vehicle and that I was still experiencing the same problem and I was brushed off saying the were sorry and there is nothing they can do about the problem. This is a problem that could potentially lead to a fatal incident because it involves the vehicle cutting of for a brief second and causing many component not to function during that second and the vehicle is not intended to function in this manner. Mercedes is not doing their due diligence to investigate and correct the problem besides the basic diagnostics that do not yield an error code. I will gladly furnish the video tape which is evidence the issue occurs.
