Purchased a New 2021 Yukon SLT in January. As of todays date, it only has 2,000 miles on it. Well yesterday the lifters went along with bent pushrods. My wife was driving it and all of a sudden she felt like the truck was coming apart, lost power, no acceleration and it was running extremely rough. GMC dealer towed it to dealership and called us with the results stated above. Only 2,000 MILES !!!!! Don't care that they are fixing it, going to try to force GM to buy it back, completely unacceptable on a new 2,000 mile vehicle. Lost all confidence in this vehicle. WTF GM !
