Crash

The brake lines are rusted from the rear sub Frame that was rusted And caused an accident. They told me the sub frame was the only item covered but that they could only bolt it and not weld if and then the exhaust and brake lines (rusted too bad to describe) weren’t covered and since I couldn’t afford it they only repaired the subframe and left the rest hanging ! My brakes failed on the way home. No one was injured but I can’t believe they let me go home with that condition!

the conductor plate along with its speed sensor is faulty. Luckily I just exit the highway, the transmission just stopped working, can't drive forward or reverse and when I apply gas on either D or R, just the RPM speed up as if the car is in neutral. I was stranded on the middle of the road. this happened a few time. after turning off the car and turn it back on usually reset it for a little bit. the first time, I have to replace the transmission.

As i was driving (on a bridge) the convertible top/roof gushed and dumped an incredible amount of hydraulic fluid/oil right in my face unexpectedly! This came out of the blue. I had just raised it since it began to rain. The combination of raining weather and being on a one lane bridge and then having that spew into my face rendered me unable to see and had Me swerving almost off the bridge as the other lane had vehicles driving. I almost wrecked and was left with highly painful eyes. In truth…

My vehicle has excessive rust issues that I’m being told by the dealership will compromise my safety. There is currently an extension of warranty for only the subframe in rear, but the rust is extended beyond that and is applied to the components needed to be removed in order to replace the subframe. Such as the exhaust pipe and brake lines as well. All are corroded to a high degree up to and including complete brittle material Disintegration. Exhaust and rear brake line cost make it impossible…

improper heat treatment of the balance shaft spocket causing the balance shaft to worn out resulting in advance timing of the CAM. Mercedes acknowledges it's an known issue but don't cover cost of fixing it. Once ecu detected timing is off, it will stop the transmission from accelerating without any warning. Happened to me on a highway, good thing the car still have some momentum and was able to pull to the shoulder while others cars are coming from behind.

The rear subframe is corroded to the point of about to fall off and subsequently anything that is attached. Mercedes has extended a warranty on the subframe which is excellent, but only the subFrame? What about the touching bits like the bolts and screws among other items that are connected to it. So now because I cannot afford the $5,000.00 needed for the other rusted pieces that are brittle and likely to fall off when the subframe is replaced, then they won’t do it. So I must jeapordize my…

The contact owns a 2012 Mercedes-Benz SLK350. The contact stated that while driving at an undisclosed speed, a loud noise was heard coming from the rear of the vehicle. The contact stated that as she pulled over and parked the vehicle, the low tire pressure warning light illuminated for the driver's side rear tire. When the contact exited the vehicle, she saw that the rim hub cap had detached from the driver's side rear wheel. The vehicle was then towed to an independent mechanic who removed…
