“The head unit quit working around 98k. The head unit is the radio, and screen which includes the back up camera. From what we have been told and find online, this is a known problem with them and affects other models as well. For the most part the head unit doesn't work but once in a while, once a month, it comes on but shows the Chevy logo on the screen which is odd because it is a GMC. Once you turn the car off, it will be gone again until it decides to come back. We took it into a dealer who tried to hook up to it and reprogram or update it, but he had no luck.

“I was driving back home when I suddenly heard a loud pop and my car seat belt immediately tightened up. I saw smoke inside the car and the screen in my dashboard said "airbag service" There was no air bag physical deployed in the car so I believe it happened internally. Now my driver seatbelt will not retract and the front passenger seatbelt will not come out.”
NHTSA complaint #11617757, 2024

“The front passenger seat belt locks on passenger and will not release unless it is completely unbuckled. It keeps doing this for no reason. This was brought to dealer’s attention one to two years ago and they said I would have to pay cost of repair since warranty was off even though I purchased an extended warranty with this vehicle. The service department claims to have taken it apart and cleaned it but could not find problem. The problem is bad since passenger has to unbuckle belt multiple times during a trip.”

“Roughly every 8 months Sirius XM "radio" runs an automatically triggered free subscription period that includes "weather alerts". These alerts BLOCK part of the car's normal navigational (map) system, requiring UNNECESSARY MOVEMENTS to dismiss the prompts so one can see map details. These movements RISK DRIVING MISTAKES. The weather alerts are unhelpful and unwanted: trivial events that don't affect me. And they keep repeating the same alert multiple times per day.

The back right tire sticks to the pavement and jerks when i start to drive. The key ignition has been fixed several times and still sometimes won't turn with the key or come out. Yes Warranty told the repaid service company to fix whatever, and they did but it still after 2 more transmission hasn't fixed the issues. Engine light and not sure what else.”

This made it even more difficult to see due to the rain coming off of their tires and spraying onto our window. We had to slow down to a dangerous low speed on the interstate due to the difficulty seeing. We made it to the shoulder after almost being hit by a semi We had to sit there until the rain stopped.
