Brake pedal will not return fully after it is applied when it is warm and humid. Causes brake pedal to stick and not allow cruise control to be selected. The stuck pedal allows the car to be started and placed into gear without a foot on the pedal. Did find that GM has not only issued a technical service bulletin for the described issue but has issued multiple revisions to cover additional vehicles each time. Given that this is a well known issue by the manufacture, this should warrant a serious looking into a recall issue. Tsb # pic5692D dated 05/11/2018 is the fourth revision and the original tsb pic5692 is dated July, 2012. Tsb pic5692D even states that a product review is required.

My brake pedal always get stuck depressed down in hot humid weather. You literally have to drive with two feet to lift pedal when time to accelerate. My driver seat also goes in and out when trying to adjust the seat. It will not move unless I play with the power adjuster a few times then it will maneuver. My radio also turns off and on by itself with bluetooth is connected or sometimes the radio wouldn't turn on with car running or turn off while car is off.

Brake pedal sticks and stays depressed when very hot outside after sitting. This needs to be recalled. Its happened twice to me already and no shop can find anything wrong. It will work fine after pulling pedal up or driving with shaking steering wheel until it works itself out. This needs to be addressed and needs to be a recall fix.

The contact owns a 2012 Buick Regal. The contact stated that the brake pedal was extremely difficult to depress. The ABS and brake indicators illuminated several times. The dealer (fremont Chevrolet Buick GMC, 1401 N federal blvd, riverton, wy 82501, (307) 240-3110) diagnosed that the timing chain needed to be replaced. The vehicle was also taken to an independent mechanic for further diagnostic testing. The independent mechanic took pictures of the failure, which showed that a bolt fractured and impacted the engine and braking system. The manufacturer stated that there were no recalls and the vehicle was out of warranty by six months. The approximate failure mileage was 35,000.

Brake pads rusted to the rotors, after hand-washing the vehicle the evening of July 2nd. Needed to rev the engine very high, in order to release the brake pads. This has occurred several times after driving the vehicle in the rain, and then letting it sit for a day or two. On Jan 16, 2015 we took the vehicle in for warranty work, but the dealer did not do anything. On Feb 20, 2015 we took the vehicle to another dealer, but again they did not do anything.
