Auto hold was on, radar cruise control was set and as I was merging in traffic a sharp smell of burning started. The cruise control refused to disengage until I parked the car in garage. Eventually burn smell ended but seems like brake was stuck while acceleration causing a burn smell. It seems like brake could get stuck to wheels perhaps when auto hold is on even when driving? Auto break hold is a feature which keeps the break on while car is stopped.

This morning, I stopped to open the gates at work, car was idling. When I got back into the car, put it in drive and started to slowly move forward the FORWARD COLLISION SYSTEM slammed on my brakes and lights flashing on my dash. I backed up...there was absolutely nothing in my way. This has happened numerous times, different places and while turning a corner at a very slow speed. Never nothing in the way. Will definitely be taking it in to have it checked now.

I had let off the gas and had slowed to about 35 mls per hour before I applied the break. The road was wet from rain, but I did not believe the vehicle was hydroplaning. They rain had stopped and roads were only moderately wet. I applied the brake pedal normally and continuously held the pedal down. I did not pump or release the brake pedal. The vehicle appeared to activate ABS. I could feel what seemed like repeated braking and releasing/pulsing while I continued holding the brake pedal down. Despite continuously applying the…

The plastic cover on the shark fin antenna has fallen off the vehicle twice now. The second time was just 12 weeks after the first one was replaced at the dealership. The part fails because the plastic clips that hold it to the base are brittle and are easily damaged by the high speed air dryers in car washes. My concern is that if the clips get weakened in the car wash and then the plastic cover separates from the base while driving at highway speeds, there is a very real potential for this part to strike the windshield of the car following my vehicle. The part in question is GM Part Number 26537604. GM has issued a direct replacement to the original OEM part number, GM Part Number…
