2012 Mercedes c250 Engine Light comes on and car wont accelerate

Asked by Feb 02, 2017 at 12:38 PM about the 2012 Mercedes-Benz C-Class C 250 Sport

Question type: Maintenance & Repair

When driving my 2012 Mercedes c250 at normal speeds
the car will all of a sudden jerk almost like you tapped the
brakes but you didn't and then the Engine light comes on
and the car wont accelerate over 15 to 20 mph. You can
hold the gas pedal to the floor and nothing happens. You
then have to pull over to the side of the road and turn the
car off. After a few seconds you turn the car back on and
you can again accelerate however the engine light stays on.
The engine light will usually go off after a day or so. This
same thing is now happening about ever other day. I am
very worried that I am going to be on the highway going 65
mph and this issue is going to happen which could cause a
really bad accident.  Does anyone know what the problem
is and what I need to do to get corrected? Please any help
would be extremely appreciated.

It sounds like your car is going into Limp Mode due to a serious problem. Get the OBD2 codes read and post them here and we will try to help. I believe Auto Zone and other car parts stores will read the codes for free.

I personally have a C250 and it has happened to me twice and it seems if you drive the car for a long period of time or accelerate sharply the car will simply decide to "Take a lunch break" turning off and on from a standstill should solve the problem, if not a scanner is what'd I'd recommend.
