Example complaints
Electrical system: “Radio has zero sound - the issue is the radio sound also has the blinker sound, hands free safety/navigation guidance along with the On Star safety function. None of that is functional. The dealer states it's a known issue and parts are not available. How can this be when they keep building new units. GM has been contacted with zero help and no response around my safety concerns. While it seems like a small thing when we say radio I'm not concerned with the lack of music but this system controls way more than music.”
NHTSA complaint #11727195, filed 2026-03Steering: “I recently purchased my vehicle from Big Star Dealership in Baytown Tx. At a little over 1000 miles i was towing a camper. The vehicle stalled, fuel pouring from engine. It was towed and repaired due to fuel pump failure. At a little over 3000 miles the vehicle would not start. Dealership initially said water contamination then changed it and said gasoline contamination and now they say DEF contamination. The vehicle stalling the first time almost caused me to wreck the vehicle”
NHTSA complaint #11737988, filed 2026-05Brakes: “Brand new delivery there was a noise that changes with engine RPM. It also changed with turning the steering wheel. The dealer diagnosed a bad power steering pump. Due to possible metallic contamination all related parts that are connected to the power steering pump including the HydroBoost brake assist are going to be replaced”
NHTSA complaint #11734694, filed 2026-04Tires: “No Incident Occurred. Tire Size 275/65R20. Tire Pressure Fluctuating between 59 and 71 PSI. 3 of 4 tires appear to have a defect.
