Hello. I purchased this vehicle in January of this year. I own a 2021 GMC Sierra AT4. Since I owned the vehicle it has been towed twice. First time was when it had around 3000 miles on it and the issue was the ECM Module. I now have 10, 000 miles own it and the Lifters on the motor are bad and need to be replaced. It has been in the shop now for 2 weeks. I have owned several General Motor vehicle. I currently have a 2006 Chevy 1500 runs great. I also have a GMC Yukon Denali hardly any issues. I am very frustrated with my Sierra product as of now. My biggest fear is if I keep the vehicle and warranty runs out what other issues will I have.
