"takata recall" when I was driving after a oil change, I heard a noise that sounded like someone hit my car. I was scared and shaky so I pulled over could see anything but I heard a ticking noise. Then I realized the head rest mini air bag blew up and the wiring inside the head rest was burning. This happened while I was driving. I could have got into an accident. I had to pull over right where all the traffic was because my hands were shaking and I didn't know what to do with the burning smell. I had my hazards on and people went around me. Then all kinds of alerts went off on my car. I only had it for a year and a half it shouldn't do that. Something is really wrong and this is dangerous while someone is driving. My tires and all of a sudden the muffler is making noises now too what is going on with this car. It's treated well I'm scared to drive it now. I'm still making payments on it. It's was for me fairly new and still good, do I thought. I'm very disappointed and need some answers. I was told that maybe it's the eps control unit but haven't went to mercedes dealer yet because I'm discouraged about this car and I haven't been feeling good.

Takata recall, brake power steering malfunction ABS,esp,ets,SRS.esb,ebr flashes on and off on message center. Then vehicle started to drive very rough and bumpy, then I had no control of the steering wheel and it totally locked thank god iwas able to try and roll it to the side of the road and the car just totally went black and died, no headlights and I have to have it towed, waiting to get the diagnosis from the dealer. But I have done some research on line and have seen hundreds of the same complaints from all over the USA and even oversees that it has to do with the eis. This saddens me to see all the same complaints and I thought that we were protected as consumers by the government, and the federal safety agency against major auto manufacturer such as mbusa to call out these deadly defects before it consumed innocence peoples lives. But it is obvious that our lives means nothing to these people, because with all these identical complaints this is a defect that should be address and mbusa should have the decency to take responsibility and admit that this is a manufacturer defect and do a recall. This is just too much complaints on this problem and no one seem to be taking this matter serious, and we as the consumers are being stuck with these major repair bills running in the thousand. What is the purpose in making these reports when no one seems to care. How many complaints do you have to receive on the same issue for the federal safety agency and the fair trade act to stand up for us, in october of 2016 this same vehicle self accelerate and crash in to two other vehicles causing a major accident and when reported to mbusa they claim they did there investigation and nothing was wrong with my vehicle, they place the blame on me .daimler ag would not believe what there prestigious company as become

I replace brake pads and rotos, and I am also being told it could also be my brake light switch or speed sensors, all was replace still as message. There is so many complaints with these messages that this should be considered a recall and the customers are being stuck with the repairs. It is obvious that it is a defect with these vehicles it is just too many. And no onw seems to be standing behind the consumers.mbusa is a major company and they are getting away with murder. Do you have to have major fatality before they do something about this problem. Does saving money means more than peoples lives it is just too many complaints on the same problems that common sense cant tell them it is a defect and the nhts should step up for us and demand a recall. How many complaints do you have to have in order for mbusa make this a recall.

I parked the car, and turned it off completely. When I returned to the car, they key fob would only turn the dashboard lights on, but the car will not start. The steering wheel is locked, and I cannot change the gear from "p". A message would appear "remove key from ignition" whenever the door is open. I have searched and it appears to be a very common problem in these models, where the eis or esl fails for no reason. The qoutes for this repair range from $1000 to $3000. I had to tow the car to my apartment, and now I have to tow the car to the dealership because they are the only ones who can solve this issue and reprogram it after installing the new parts.
