Engine failure while driving 75 miles per hour in highway in brand new Yukon Denali. 3,000 miles and got a “decreased acceleration” warning. Then couldn’t accelerate and loud knocking noise from the engine, likely a lifter issue. I will have to get a new engine according to GMC. Unbelievable. Recall was for 2021-2024, but my 2026 is havin the same issue.
