“I had been driving on the freeway, got off onto a side road and when approaching a stop light while braking: my car completely died (while in drive). The motor shut off, the electrical dash system lights all went off and the hazard triangle system came on (with the symbol of an exclamation mark(!) inside the triangle). After about a minute and a half, I put it in park, and it restarted. Scary! I had a full tank of gas.”

“I was driving four days after I leased my brand new C250 2014 mercedes, and the car died in the middle of a busy street. The cop and I couldnt even move it to the side of the street. I am worried this will happen again. Thus I have been calling mercedes to please replace the car with a safe one.”

“Random engine stall involving turbo and intercooler: we purchased this 2014 C250 with roughly 8,000 miles from nearby mb dealer. We have enjoyed the car immensely, exception this very serious defect with the engine. Observed on three separate occasions, this problem is very serious and could lead to potential collision while passing another vehicle, because the engine stalls under intense acceleration randomly, leaving only one cylinder working. …”

“In june of 2018 we had to have cam shaft work done on our car which was slightly over the manufacture warranty. This took two trips to the shop and about $10,000 in repairs because the one side failed then within a few weeks the other side failed. I have read on the web many people have had the same issue and it begins right after the warranty goes out. Now there is an issue with the timing chain which I read should have been replaced when the cam shaft work was done. All these issues with the same model and there has been no recall. …”

“Leased our mercedes and shortly afterwards we started experiencing hesitation, lagging and even stalling of the vehicle as we tried to accelerate. Twice the vehicle has stalled as we pulled into traffic, narrowly escaping possible injury and damaging several cars. Hesitation has occurred without warning, (pressing on accelerator and the engine does not respond by evidence of no RPM increase). Again, this has occured numerous times. We have had the vehicle back to mercedes four times, for a total of 39 days!!!! …”
