New problem....
Has this happened to anyone before?
Has this happened to anyone before?I have heard of someone slamming the brakes and the car stalls but never have I heard the brakes braking on their own.
Try to get a CANOBD2 reader and see what the code is and maybe we can help you.

SSM is talking about the problem Benz had on the brake by wire set up on the E Class.I've never experienced this on a C unless you are driving like a maniac and the ESP, BAS etc spoils your fun by saying enough.
I suppose it's possible that the ESP module has gone duff or the yaw sensor if your car has one. Some do - some don't. Mine has because of the BiX. Or some sensor sending a wrong signal to the ESP. Before we start guessing
Hubertt - has your OBDII scanner arrived yet??
Are you sure that the car applied the brakes?
Are you sure that it did not just close the throttle automatically? With the torque converter locked you have a lot of engine braking power
Are you running different size wheels on the back to the front?
Answer these questions while I scratch my head.

That's where I'm going with my questions above. I think the ESP got upset by something and put the car into limp home mode which could feel like the brakes self deploying.
One thing that can cause an ESP malfunction & other problems with The ESP & TCU is rolling circumference of rear & front wheels being more than a couple of percent different hence my wheel question - This can also cause limp mode to engage.

I believe that a one time incident triggered limp mode. Rebooting has cleared the issue - might still be some stored codes.
Has this happened to anyone before?I have been experiencing this same problem for the past 3-5 months on my 2001 C240. I have taken it to the dealership where they have aligned the car, replaced the ESP unit, and adjusted the YAW sensor. The dealer still cannot figure out what the problem is.
The front right wheel locks up for a second and then triggers the ESP Error message. This happens almost everytime I turn the car on and it happens when the car is standing still, accelerating, etc...
