Reply To: 2024 Sierra 6.2L Problems

I’m new here. Yep. Engine failure at 1,000 miles. Sierra Denali 1500 gas 5.3. Metal in oil. They are (in touch) with engineers. No diagnosis yet. Been in dealer for a week. New engine is a very long wait they say. More to come. If I can qualify for the California lemon law (vehicle in shop for 30 days or more) I’ll get out of this GM product and run the other way.
