Takata recall I was involved in an accident on jan 3, 2015 in my 05 mer benz c230 the airbag exploded causing smoke and dust like particals I immedietly got off the car from that point on the car has been sitting tottalled I recently recieved a recall notification on 2/11/2016 I find it hard to believe this is the…
Takata recall: I had a front end collision and I am concerned that my airbags did not deploy. The impact in my opinion was such that caused me to wonder why they did not inflate. My primary concern is if they work at all. My car was in motion on a wet highway at the time of impact around 2pm.
Unintended surge in accelerator. I was reversing into a parking stall in the garage of a condo complex. This is a compact stall with only about eight inches of space from the tire to the dividing line, so I need to park very carefully and slowly.
The car shakes (the k frame) and the steering wheel has a lot of play in it which I was told will always be like that unless I get it repaired. I have put an insurmountable of money into this car and I'm very disappointed.
Vehicle began smoking on highway. No check engine or indicator of any fault codes. No previous coolant or oil leaks, or fuel leaks appeared to be visible or of issue.
Then the engine light came on and now it want go in reverse. The electrical has went out for moving the headrest up and down, moving the seat forward n backwards. The battery keep draining, this is the 3rd new battery I had to buy. It's still beging drain.
Also numerous time speed has accelerated independantly bumped in parking lot no air bag deployed seat malfunctions when moving it its stuck and crooked cant reach pedals and loss of power even after fuel repairs before as well. Sunroof motor works when it wants to and constant fuses blowing and lights all the time.
