| Suspension problems |
The truck when put in parking it still roll forward a little bit. Back up camera can’t not see during night time. Dealership stated they will not solve that problem and tell us to do manually by turn around look back. The suspension really bouncy but the tech stated that is normal. Spoke to other 3rd party tech they said that not normal at all.
I purchased a 2025 GMC siera denali ultimate in December 2024. Approximately 2 weeks after purchasing the vehicle, I was driving down the road I received a message that said, "service suspension". I was able to call onstar for diagnostic and the truck was throwing code c2a0a. I took the truck into the dealership to see what the issue was. The dealership said that I apparently ran something over and it must have flown up and broke a plastic sensor cover on the lower rear left shock. I never hit anything but have no way to prove. So, I had to pay $526 for a new shock. Even if I did run over something if that area of the shock is that sensitive it should be better protected especially if it's not covered under warranty.
