“I purchased a 2007 mercedes benz C230 sport from a private seller. I soon learned that the vehicle was in limp mode. The dealer said it was the transmission conductor plate. After hours of research, I discovered several owners of a mercedes with the 772.9 transmission have been experiencing the same issue. I ended up paying $2500 for a new tcu from mercedes benz.”
NHTSA complaint #11360040, filed 2020-09, 184,000 miles“There are issues with the engine and the car will not start. There's a class action against mercedes in regards to this same engine issue. The car was in motion when it cut off and another time after being stationary the car would not start. There was never a check engine light or any signs that indicated engine issues before the engine completely failed. I also received a notice about my airbag having a recall about a year ago and this issue has not been resolved.”

My car has been experiencing transmission issues of the car not down shifting into the next gear and the car's speed declining while driving. This has happened driving on surface streets at 20mph and on the freeway going 65mph. I've even attempted to take it out of automatic drive and into manual shift and the car will not respond. The only way to reboot it is if I pull over and turn the vehicle off and restart it after a few minutes. …”
NHTSA complaint #10542684, filed 2013-09, 35,000 miles“2016 I took my 2007 mercedes benz C230, into mercedes benz to see why the check engine light was on. My car was purchased with 37k miles on it at the time I purchased it. How could such a major issue, arise in car so early in it's life. Mercedes stated, that they make the best quality of cars in the world! They stand by this slogan. However, why would such a major issue occur in a car with such low miles/usage? As I understand it, matters of this magnitude ideally does not occur in such a quality car, let alone in the cars infant stage or would likely happen at all! …”
NHTSA complaint #11055097, filed 2017-12, 37,000 miles“I purchased my car brand new, it was never previously owned and directly from a mercedes benz dealer. I started having problems with speed and gear shifting back in may 2012. When driving on the freeway normal speed (55mph) the car would begin to slow down no matter how much I pressed the accelerator the car would slow to a complete stop. I would have to attempt to pull over off the freeway, turn the car completely off, let it sit and then start it again and the car would run normal. …”
