Poll on lifters

[20Tahoe21]

what is your experience with lifters?

 

[TrueAt1stLight]

Failure at just shy of 13k miles. 2021 Yukon Denali with the 6.2L. I need to look at the build date but somewhere between 1/1 and 2/10 2021.

Not sure you are going to get anything meaningful (statistically speaking) from your poll. I didn't vote as my truck was built in October, hence doesn't have enough miles on it to be a fair test.

I think you should also include current mileage and weight your results accordingly.

 

[Shrubs2K2]

Failure at 9800 miles

 

[DougAMiller]

No failures at 11,000 miles

2021 Z71. 13,700 miles. No issues so far. Been driving in L9 the last month or so. Mine doesn't have the build date on the door jam sticker. So no idea when the engine was made. I picked it up Mar 2020, so build before then is all I know. Saw a post about checking the engine cylinder or something, but have no idea where to actually look.

2021 Yukon Denali, failure at 30k miles and failure at just under 36k miles.

You certainly need to include build date if it’s within the range that GMC has in TSB. If this is a basic design flaw as claimed by some then we should see failures outside of that build range.
