Mercedes-Benz C 300 Recall 18V909: Parking Brake May Not Release Unless Stability Control Is Off

NHTSA campaign 18V909, reported December 19, 2018, 675 vehicles potentially affected.

What this recall means for you

On certain 2019 Mercedes-Benz C-Class vehicles, the Electronic Stability Program (ESP) software can keep the electronic parking brake from releasing after you park, exit the car, and return to it. The brake will not disengage unless the ESP system is turned off first.

If you drive with the ESP system deactivated, the risk of a crash can increase, because the stability control system is not working to help keep the vehicle under control.

Mercedes-Benz will update the ESP system software at no cost through an authorized dealer. Owners can contact Mercedes-Benz customer service at 1-800-367-6372 and reference recall number 2018120025. You can also check your VIN for open recalls to see whether your vehicle is affected.
