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.
When gas tank is near empty and engine dies while traveling downhill at a 15 degree slope or greater. Consumer very concerned about safety due to hills in area being very steep, and vehicle stalling.
At 60+ mph my high pressure oil line crimped fitting let go. When this happened I lost 5qts. Of oil all over my front brakes, marking it very difficult to come to a stop. These fittings should never fail, but last the life of the vehicle. It is not a part that wears out from use and if so, 61,000 I think would be to soon? I have over the past two weeks tried to get GMC to respond to this as a serious problem, to no avail. I also explained to them that at 60 mph I could have lost both my power steering and brakes if the motor had seized do to lack of lost oil. No response. I also explained that the shop where I have my work done has had 4-5 of these failures in just the last 2 months and told them to contact my tech. To find out more, again no response. The other problem is when I lost all my oil at such a rapid rate I now have done some serious damage to my engine, which I feel could still seize. I feel they are responsible and are avoiding not only the damage to my engine, but the fact that this failure has happened 4-5 times at my shop. Please feel free to contact me asap with more detailed info. Their lack of customer concern, safety, and damage that this defect has caused is why I felt it was important that I contact someone who needs to address this problem. This engine damage could cost me a new engine thru no fault of my own.
Engine check light was coming on at 30,000 miles. At 77,000 miles egr valve was replaced. Then, less than 25,000 miles later egr valve needed to be replaced again. Vehicle was running very rough/ stalling at lights, eventually no brakes and a horrible smell when door was opened. Dealer knew there was a problem but has not rectified it.

I was pulling into my driveway, when the engine started running eratically. When I started to slow down I noticed the brake pedal was hard and it was very difficult to stop. Fortunetly I was going slow or I would have literally gone through my garage. I was able to get the car to a mechanic who replaced the egr valve.
Oil lines running from the engine to the oil filter then to the oil cooler leak. Leak got worse and blew out one of the lines and caused engine to lock up on freeway.
When brakes are applied and fuel is below half a tank, the vehicle stalls causing lack of steering and braking control. This has occured on multiple occasions (more than 10 times) nearly causing an accident during the most recent.
Rear window would not lock--bolts holding the lock needed tightening. Transmission not shifting. Engine overheats. Tire blowout. Front brakes fail. Engine stalls. Owner wants to be refunded for car.
Original engine failed at 104,616 miles (approx 1000 miles from home), taken to dealership and was told replacement engine would be installed within 2 days. Waited 24 days for completion of job (during this period was told the new engine was installed, and to come retreive the car. Upon arrival, car was not done). On July 2 returned to dealership to pick up car, the car made it approximately 70 miles before it started with loud knocking noises and a severe decrease in power. Car is now at another dealership (900 miles from home) who states "you need a new engine."
Knock detected in engine. Bearing failure - engine replacement recommended. Engine was well maintained, as confirmed by inspection of internals. Probable cause said to be inadequate oil supply to front end of engine.
