The stabilitrak system has an incorrect calibration that may cause the system to not properly detect if a sensor were to malfunction, and the warning light indicating that the system is not operating would not illuminate, as required in the safety standard. The stabilitrak system falsely activates resulting in sudden changes in vehicle handling and deceleration, particularly at higher speeds, which may cause the driver difficulty in maintaining the vehicle's desired path of travel and desired vehicle speed, and could result in a crash without warning.

Brake lights may stay on when the car is parked and the engine is off. This is due to the brake pedal may become sticky intermittently as per GM's Service Bulletin: SB-10045319-1529. At times, while pressing the gas pedal, the car may not move at all and it can become a safety hazard for the driver and drivers behind you. However, as of 5-8-23, GM does not have an open recall for this safety issue and may lead to an fatal accident. Please investigate this issue and possibly open a recall notice as this could cause a serious safety issue.

We're purchasing this vehicle from superior Auto, and we seen a recall back in 2011/12 from stabiltrak and deterrent auto theft, since this $21, 240 car we've had issues causing the car to shut off and lock up without warning, no power steering or brakes, and stabiltrak and auto deterrent theft warning pop up, and had it to 2 mechanics that are baffled and it produces no codes, I've almost gotten in 3 accidents causing this, and now I'm too scared to drive this car, the recall had same issues for improperly calibrated ESC defective sensors not showing codes, nobody will fix the issue without codes and I don't need to hurt or kill anyone. Superior Auto is not caring about taking this car back or trading it in, please help me figure this out, there was no accidents, but this car is unsafe for the road

The brake pedal sticks down during interior high temperatures (generally during the summer months when parked in the sun) and causes the brakes to drag. It appears this is a known defect (nhtsa# 10141352) gm technical service bulletin#PIC 5692D. I just want the NHTSA to be aware of another vehicle exhibiting this condition. I will be repairing the vehicle myself.

I was driving my car to my house an my car started acting funny. While driving randomly 2 lights came on saying service brake assist and service stabili track. It became extremely hard to steer, the automatic brakes stopped working and it cut off on the highway. I put it in neutral and got to the side of the road. When I cut it back on it had the following warning lights; service brake assist, service stabili track. I almost died and my girl had to pay for a tow truck for me to get home and I was right up the street. I feel like it dangerous and when I told GMC they said its nothing they could do. It is several recalls with vehicles just like mine that are the same year with the same problems but they said they would not help me. My car is not drivable and I can not afford to get all the things fixed that were recalls. I am immobile and it is causing harm to me financially. I trusted GMC and I feel like they should do right by consumers.

After pressing the brake pedal down, the pedal does not return to the home position. It remains depressed and the brakes will only disengage after I manually lift the brake pedal. This occurs when the weather is warm out and occurs in all stages of driving when this happens (stationary, in motion, etc).

The engine light had come on and I went to a repair shop to have it repaired. I was told to bring it back the next day and on my way back the charging light came on. I was on the highway doing 70 miles an hour in a curve when all systems went down the instrument panel lit up and I lost braking, steering and all other functions. And I was very lucky to not have wrecked the car. This is a very dangerous situation that needs to be corrected.

When driving my car on declining grades the "traction control" light will appear and the car's front brakes will automatically slow the vehicle down. This happened on 1/21/2018 most recently and almost caused an accident as the person behind me wasn't ready for my car to come to a complete stop.

All power features shut down while driving on street. Loss partial control of steering, braking power was reduced significantly and engine shut off completely.

I purchased this car from another car dealer in early July 2014 with 19,000 miles. I noticed that the vehicle seemed to be sluggish on acceleration. I first thought it was the electronic parking brake not releasing. After doing some research I found another case where some else had their car in for the same issue. They said it was the brake pedal bushing not allowing the pedal to disengage the brakes once they were applied. I was told to drive to the dealer even though I told them it was unsafe. By the time my wife drove the car in the brakes were about to caught fire because they were not releasing. They replaced the bushing and turned the rotors that should have been replaced. I am taking it back into the dealership for warred rotor would be my best guess; this is a fire hazard waiting to happen. There was no fire but if she would have driven another 10 miles the brakes would have been on fire. I arrived at the dealership twenty minutes after my wife and the brakes were very hot and smelled the same. I checked yes on fire because there would have been one shortly.

This is a 4cyl car with easiest. Unintended acceleration - the car while going downhill or sometimes uphill, accelerates on its own after releasing the gas pedal. I almost hit another car once because of this. Jerking - the car while decelerating from 50-40 mph to 30-20 mph jerks after releasing the gas pedal (with an intention of decelerating) or while applying brakes. This has been happening regularly since I bought the car in Oct 2012.

Un smooth shifting around 30 mph, causing the car to jerk or brake feels like the assist is not sensing, causing the had to dealership nothing they can do all check out but the problem is still there.
