Exclamation My Car Accelerates By Itself

Hi, I have a 1991 Mercedes C-280 German Spec Automatic and it has the tendency to accelerate on its own. I have to slam my foot on the break or it will keep going, often once I have removed my foot from the break, it does the same thing. I was wondering if any of you knew what might cause this. It is very annoying! Thanks

It's also very dangerous

You need to report this to the NHTSA as a dangerous defect. Your accelerator cable is sticking. Happened to me on the ML430 about a month ago. I geared it down while aggressively applying the brakes to stop. It hasn't happened again but it could at any time.

Hi, Thanks for your information. I actually live in Germany so I would not know how to report it but thank you. It is not a cruise control problem, as I do not have a cruise control. Is this something that I could have fixed if it is what you say? My husband is deployed and he normally deals with these types of things. I just do not want to be ripped off any information would be great. Thanks again.

It may be a weak throttle body return spring, or some part of that mechanism may be sticking. Or, your car may just wanna GO!

Well there are speed limits on the Autobahn despite what my car thinks! Thanks for the input it is all wonderful, thank you so much. I told my husband what I put and he said that I needed to explain a little better the problem. What happens is when I am driving the accelerator literally compresses itself and speeds up, this can happen if I have been driving for an hr with no problem. I then have to put my breaks otherwise it will literally speed up (I let it get to 170 once!) I am not trying to fix it myself I just don’t want to be ripped off, as a woman alone in a foreign country I have sucker written all over my face!!!

This must be a W202 car, a long time ago when I had one, but it was a diesel (surprise). It should have an electronic accelerator with some basic diagnosis support, including fault codes. Reading the codes could help.
