This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The engine light comes on, then "service stabiltrak light" comes on. It starts by making it difficult to accelerate at a red stop light when it changes green. When turning a corner, because there is no quick acceleration, it has caused near miss accidents. As time goes on it becomes worse. I have lost power on the expressway and have to pull over. I have brought this car in several times and GMC has not made any repairs. It is scary when a semi is rolling behind you and you can't accelerate to get out of the way. This is a safety issue. I have received no help from GMC.
Husband was traveling under 25 mph up hill and two vehicles ahead of him abruptly stopped for unknown reason which resulted in the vehicle in front doing the same causing my husband having to hard brake. As he tried to stop the vehicle the brakes wouldn't respond and car kept rolling resulting in an accident. The ABS controller failed
When brakes are applied the vehicle takes extremely long time to properly stop. Brakes feel soft and fade when applied and I have nearly struck vehicles from the rear several times when attempting to stop. I took the vehicle to an independent mechanic but, no obvious defect were found by the mechanic. I fear that the brakes are not properly functioning in this vehicle and it is a factory defect.
I had a temporary brake failure at 25mph with a hard brake. I had a car pull out in front of me and I had to hard brake. The brake pedal was soft and went all the way to the floor with no braking until it was all the way to the floor and it finally worked with a sudden stop/jolt. When this happened it made a low sort of almost vibration sound. I did not feel a vibration in the brake pedal though. The brakes worked well before that and after that. If the brake would have not suddenly grabbed when the pedal was to the floor I would have hit the car. I was going about 25mph. I know what it sounds and feels like to have worn brakes and rotors. This was not it. Again it was a temporary failure and after that the brakes are their normal firmness and responsiveness. This is definitely a safety hazard as it very unpredictable.
