The rear center brake light stays lite even after taking foot completely off the brake pedal. I have to manually with my foot lift /push up the brake pedal lightly in order to have the brake light turn off. This happens very frequently when driving in heavy stop and go traffic on the highway.
I have had many issues with my brakes on my 2012 chevy Cruze. Sometimes it feels like I am hit from behind while stopped because the vehicle will randomly lurch forward an inch. Then, the brake lights began to randomly come on when the car was not running. This caused the battery to die numerous times. Eventually, the check engine light came on and the fault said the brake pedal position sensor was bad. I had that replaced. Now, the brake pedal does not come all the way up when it is lightly depressed (like when slowing down just a little or cancelling the cruise). This causes the brake lights to stay on. The only way to fix it is either hit the brakes hard or pull the pedal back up. I have been researching this and it appears that many people are having similar problems. TSB #pi0928/NHTSA id #10052020 discusses the "lurching". TSB #pic-5862/NHTSA id #10053904 doesn't say it's for Cruzes, but appears to be the same type of problem.
The brake lights would randomly come on and stay on when car was off and sitting still. I replaced the brake pedal position sensor and it seemed to stop. Now, the brake pedal doesn't come back up all of the way after applying the brakes. This keeps the brake light on and the brakes slightly applied. The only way to get it all the way up is to pull it from behind with your foot. This seems to be part of the brake pushrod and brake assist issue they are having, but haven't done a recall.
