2021 Silverado 5.3 Ownership Experience

[crj19]

My build date is 3/21/21, I have just over 9000 miles and took it to the dealer today for lifter failure.

My build date was December 2020. 

 

I have 2021 4x4 crew cab, standard bed lt, 5.3.

 

Zero repairs in 27,000 miles. It does downshift hard into first gear part of a day every 7 to 10 days, but shifts perfectly the other 7 to 10 days. So if it didn't have the hard downshifting into first gear 5 percent of the time I'm driving it, it would be pretty much perfect. Knock on wood no parts have been repaired so far on my truck.

Well to my shock, I got my truck back yesterday after only 3 days at the dealer. Failed lifter on cylinder 6, they replaced all 8 lifters on that side along with one pushrod and the truck runs great again.

Wow, that's fast; I'm pretty sure the final repair for ours was about two weeks. Our truck got repaired around 1800 miles and is about to roll over 11,000 soon without further lifter-related issues, but I'm definitely keeping a close eye on it still.
