When removing the electronic parking brake, to begin driving, one or more brake pads get stuck to the rotor then is violently returned to the open position. This happens in weather below 40 degrees fahrenheit, after driving, then parking for mere minutes, even when the car is still running. Many sources this is due to the master cylinder not having enough pressure to relax the caliper. This is very hazardous under low speed and I have experienced extremely weak braking when in a parking lot.
Applying brakes gives a non-linear response that makes it difficult to brake smoothly and safely. Applying the brakes results in varying responses that appears not to brake and then suddenly grabs. I suspect that there is either air in the system or part failure of the brake booster or master cylinder. Dealer said that it is �normal� brake response for this model of vehicle even though the salesman and service tech felt the problem upon driving. Also had collision brake mitigation problem light go off on my way home from dealer.
