I had engine failure two weeks after a schedule maintenance that included a tune up. When the engine failed all the components made the vehicle impossible to operate much less bring to a stop safely. I had to get the vehicle towed to the dealer. The dealer confirmed that the engine (6.2 V8) has a known documented issue. The vehicle is at my dealer with the engine being disassembled. There weren’t any warnings as I stayed on the maintenance schedule that the dealer mapped out since my purchase. The problem began 4/12/2025. After researching the issue I found this online. That is how I found your web site. https://www.youtube.com/watch?v=tgv1JDmFy-U
