Engine

17 reports1 crash1 fire
“purchased brand new December 2022. 7000 miles had issues with brake noise. dealership resurfaced rotors. 28000 miles turbo had to be replaced due to "reduced engine power". Was told a seal was the problem in the original design. 45000 miles a/c would stop blowing and produce extensive condensation on middle vents and "shift to park" became a problem. dealership cannot "reproduce" issues and therefore states nothing is wrong, although research shows problems exists and there is a back order on switch/shift assembly. Hopefully these problems "show" themselves to the technicians before extended warranty runs out, better yet a recall be issued.”

Service brakes

15 reports
“I reported my first issue back in late 2024 of the brakes squealing they took my car in and resurface the rotors. It stopped squealing for about a few months and now we are in summer of 2025 and they are squealing again. I took my car to the dealership because they told me that my car would be under warranty for 30,000 miles with the brakes. First started when they told me that the guy that told me I would have a rental car waiting for me did not set me up for a rental car. I live 45 minutes to an hour away from the dealership. When I pulled into the garage, I could hear the squealing of my car. When I went up to the counter the guy told me he couldn’t hear anything. They then tried to tell me that I would have to take my car back home and call back in the morning to talk to the rep I was talking to in the service department as he had already left for the day along with his associate. I was determined that I was not leaving there without a rental car and my car to be looked. I finally went in on my own to find the gentleman who sold me the vehicle who I really do appreciate and have no issues with him(Keith Keys) he’s a very good sales person at Weber…”

Power train

10 reports
“The shift assembly is going bad and causing a Shift to Park error that GM is aware of. They have issued a Technical Service Bulletin about this exact part. The error code will cause the battery to run down leaving me stranded. The dealer has inspected the vehichle and ordered the necessary part to replace it. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others but is available to have an inspection done. There were no warning lamps for this other than the Shift to Park error showing on the display when the car has been turned off. These error messages started happening around August 1, 2026.”
