Complete engine failure while operating the vehicle with our children riding along as passengers. The engine failure nearly caused us to wreck. 2023 GMC Yukon XL Denali with only 15,000 miles. And now, I am being told that I need a complete engine replacement and that GMC is well aware of these engine failures and the product defects, yet GMC has refused to issue a recall. To add insult to injury, I’m being told by dealership that it may take several months to get a new engine! We will be pursuing legal action.
