I purchased a 2023 Yukon Denali Ultimate new in December 2023. It has 25,000 miles on it. Last week my wife was driving on the interstate and the vehicle abruptly shut down leaving her stranded on a narrow shoulder on a bridge. After it was towed to the dealer, the diagnosis was a connecting rod failure requiring an engine replacement. It was in the shop 2 weeks prior because the vehicle shifted into neutral on its own while driving at 60 mph on the highway, but the dealer found nothing wrong
