When I first purchased my new 2022 Chevrolet Silverado 1500 RST(6.2L Engine), i noticed a knocking noise under acceleration around 3-5000 miles. I took the truck into Tom Naquin Chevrolet for my first oil change around the 5k mile mark and notified them of the noise. And over the course of the next couple years, i mentioned the knocking noise every time I took it to Naquins, every 5k miles. Chevrolet deemed the noise as normal and told the dealership to perform no further inspections on the motor. The last two oil changes, I notified the dealership that the noise was getting worse and more noticeable when slightly accelerating. They heard the noise and reached out to chevrolet again and the same thing, they deemed it as normal and advised the dealership to not further investigate. Fast forward to November 30th, 2024, I had my family in the truck and we were driving back from getting a Christmas tree. When we left the tree farm, i noticed the knocking noise was significant and I had no power when accelerating. I dropped my wife and kids off and took my truck straight to the dealership. The second i pulled in, the truck shut off and the motor seized up. It has been at the dealership since that day and the replacement engine is still on backorder with no ETA provided.
