I was driving approximately 45 MPH and my 2023 Yukon STOPPED completely and it would not move at all, it stopped just into where the intersection starts. After 2 hours it was towed to the GMC dealership. I am now told that it needs a new engine at just 15,000 miles. Apparently this is a thing I had no warning whatsver. The dealership has it now and it is waiting on a new engine. Extremes scary and now they said they will put a new one in and it shouldnt happen again. Ridiculous Engines are on back order for at least 60 days because of this problem Im told.
