    I am experiencing this too while I wait for GM to buy back my lemon. Cannot wait to be done with this truck!

    Engine Failure on New 2021 Yukon AT4

    Quick update on my original post. Today the lifters failed again, now for the third time at 14,000 miles. Car has been a disaster.

    Engine Failure on New 2021 Yukon AT4

    Thanks. I leased the vehicle, so not concerned about long-term performance. However, I just no longer trust the reliability of this vehicle. Both lifter failures occurred with my wife driving the vehicle more than 3 hours away from home.

    In my state, the vehicle may be considered a lemon if it sits in repair for at least 30 days. I am assuming days waiting for parts would also be included in that 30 days?

    Engine Failure on New 2021 Yukon AT4

    My new 2021 Yukon with 3,000 miles on it already has had an engine failure. The dealer says a lifter failed which in turn damaged a pushrod. The worst part is that the replacement parts are on backorder with zero estimates on the delivery timing. Super disappointing on a brand new car and my...
