What's up with my Mercedes C-Class?

The collision avoidance system and traction control keep switching off on my 2016 Mercedes-Benz C-Class. When I switch off the engine and restart everything is ok again for approx 20km when they act up again. Any ideas?

Hi Charles,

Sounds to us as if one of the system's many sensors is not working properly, causing the system to shut off. We recommend bringing the car into a Mercedes dealer to have it looked at. It should still be under warranty so hopefully it won't cost you anything.

Let us know what it turns out to be.
