Purchased the vehicle 300 miles away. Flew out, picked up the truck and drove it home. Got back Saturday night. Woke up Sunday morning to review the features, etc. Noticed a major oil leak. Called the dealership I purchased it from. They told me to take it to a (local) dealership. I took it to my local dealership. They looked at the vehicle. Initially they thought it was a faulty valve cover gasket. They ordered the parts. When they actually started taking the vehicle apart, the issue was not the valve gasket but the crack in the valve cover itself. They replaced the valve cover. It went to the dealer on date 03/03/2025 and they gave he vehicle back to me on 03/21/2025. They said this crack had to of happened on the production line but before it got delivered to the initial dealership.

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.
