Had to rebuild engine 5.3
Lifter failure here on my 2021 SLT 5.3 at 36K miles...took almost 2 weeks as well. I was shocked at a lifter failure. Had a 2017 5.3 that was great, only had the AC issue on that one. At least they gave you a car...they literally didn't give me anything. Had to figure that one out.- juicysmollet
