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.
On 15 plus occasions, while the vehicle is stationary, in the parking gear and running, the front end will start to vibrate mildly, increase in intensity and then the traction loss light illuminates, a blinking engine light illuminates, "service stabilitrak" and "service traction control" messages appear. Then traction contol off appears, followed by an audible loud click and vibration ceases, messages disappear and lights turn off. Once while vehicle in drive and being operated on a roadway, I pulled right at an intersection to have this same sequence happen during driving, resulting in an almost complete loss of power and acceleration and a near accident. The sequence was identical and once the errors cleared the vehicle accelerated rapidly and forcefully. I have documented multiple occasions on video while stationary over a multi month period and have furnished those documents to my local GMC dealership which has failed to repair this issue and today returned my vehicle to me with an apology for not being able to remedy the problem. They claim that the vehicle must exhibit this behavior in their presence to warrant a fix. The vehicle is under an extended warranty that clearly covers these problems. I would be happy to email the videos, but they are not in the supported format and likely larger than 5mb.
Side detection, front and rear cameras failed due to corrosion of harness (84004718) and two modules (84031087). Replacement of these components required to repair problem. Had to wait over a month for replacement parts. This is a safety hazard.
When driving stablitrac, ABS, all wheel drive fails giving alarms on the dash. SUV starts so shutter and loose acceleration. If the car is stopped and shut off it will clear. When you start driving again it will randomly do it again, such as when you turn a corner or pull out to pass someone. I has happened a couple of times. The last time was worse. I almost got hit because it lost power. Looking on line it looks like the same problem that other GMC vehicles have a history of.
