“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.”

NHTSA complaint #10561362, filed 2014-01, 60 miles“Driving on a four-lane street (two lanes on each side) with my two kids. The 2014 C250 had a malfunction with the electric steering: automatically jerking the car to the right. I lost control of the car and hit the curb. It felt like we went airborne. I turned the steering wheel to the left to try to stabilize the car, quickly realizing there was truck to the left I turned the steering wheel back to the right to avoid hitting the truck. This caused me to hit the curb again. It all happened so fast it was hard to stabilize the car. Mercedes-benz (expressed as mbusa) had my car for over a month. …”
NHTSA complaint #10671406, filed 2015-01, 3,000 miles“My Mercedes started smoking from within the cabin. I traced it down to the speaker in the car. I contacted the Mercedes dealership and told them that my speaker was burning and smoking. The service advisor knew exactly the problem and said that the factory amplifier went bad and is causing an electrical issue in the car. He had seen this before. However, Mercedes is not considering a safety issue nor doing a recall. However, I was told I should not drive the car and have it towed. So, if my car can catch fire while driving from a faulty amplifier, that would be a safety issue. …”
