2021 Z71 traction control failure

[RobFog]

GMC please help. Our Z71 Tahoe is going thru the same thing again. Traction stability system failure, check engine light, won’t accelerate. Engine knocking, etc. 6 months ago we went thru this and the dealer replaced all the lifters. Not just the two that were blown. This is a know issue. This time we are stranded 800 miles from home in a snowstorm on a Sunday. Praying

This definitely sounds like the lifter issue. Once the lifter issue happened on my 2021 Yukon Denali, all of those lights went on, as well. THe service person said that the computer disables anything that could be hurt by the failure...that's why it all lights up... Don't let them tell you it's just a bad lifter issue...it's the engine design and those lifters were replaced twice on my vehicle and it's still unreliable for $95K

I'm new to the forums and trying to figure out if there's a way to mitigate the lifter issue at all (been driving in L9...not idea if that helps). Have a 21 Tahoe Z71 w/off road package/air suspension. Got it March 2021 and about to hit 13,000 miles. No issues so far...but zero piece of mind at the moment that a lifter may fail and strand me in the near future. Kids play travel sports and literally driving 200+ miles every weekend.

This is almost certainly the pre-game for a lifter failure. That's what happened to me. I got all the warning lights before the knocking started.
