NHTSA Complaint #11671801 — 2023 GMC SIERRA 1500

After 1-year to date of the first time the engine seized up in 2024 and was replaced with another motor. Then around father's day weekend I went to accelerate on highway and it studder and service symbols for traction control and ESC service popped up. It shook and vibrated while running. The same dealership shop that replaced it last year stated that rods and such have failed. After not resetting the mileage on the dash board for the miles on the truck or extending the warranty on the AT4 2023 model I was skeptical as it ran rough to begin with. I was told that everything is as should be when talking to them in Jan/Feb 2025. Now we're here at the shop AGAIN. the Mechanic at the dealership the first time stated that he mentioned to the manufacturer that the issues he is seeing is tied to the motor and oil transferring and he is not surprised there are the issues but the manufacturer shrugged it off. So, after having the vehicle in my possession for 2 years, I'm having the motor replaced twice in one calendar year and without a vehicle combined and counting 2.5+ months. GMC knew about the issues and decided not to address them. I loved the truck but there were too many issues and it was my first GMC and will be my LAST. I WAS a big Chevy guy most of my life.. Now I'm considering a RAM..
