Lifter failure......

[CLandry]

2021 Elevation 8500 miles..... 

started riding really bad and throwing esc codes amongst others....

towed to dealer.....

dealer says it’s lifter issue that was reported allot in the 19-20 models

beyond pissed....this is rediculous.

anyone else experience this issue, and can it cause any long term reliability issues down the line?

What engine?  

 

Sounds more like a busted valve spring if it is a 6.2 and might require a new engine

Looks like there is a TSB for this:

Good to hear, never had a Situation like this this early in owning a vehicle

My 6.2 had 4,500 miles on it when I got a tick and codes....

 

Valve spring broke and took the entire engine with it

The  referenced TSB doesn't appear to apply to model year 2021, but maybe I missed something.

Seems so unfortunately, I was thinking the same thing

Really hoped this would have been resolved by 21 model year but apparently not....

been at dealer since Monday, and they say it will be back to me tomarrow afternoon hopefully, but didn’t give any specifics as to what will be performed other than saying they will know more when they tearing it down....I don’t even like the sound of that honestly

I have a 2019 silverado 5.3 and in I had 2 bad lifters on driver be side so all lifters on that side were replaced . Truck only had 11000 miles. Dealer repaired under warranty and actually runs better than first bought. Black sunshine now has 19000 miles and runs great

Just to let everyone here know this has been an ongoing problem since 2014!

 

So if anyone is thinking will the 2022 models be different, only if the 5.3 and 6.2 are not offered!

I had this happen on a 2017 6.2 liter Silverado at about 65,000 miles. Dealer had to replace 4 lifters and a rod guide. So I traded that truck for a 2020 Trail Boss with a 5.3 liter engine (since my last 5.3 Silverado didnt give me any problems). The Trail Boss dropped 16 lifters, bent 2 pushrods and damaged the cams at 31,000 miles. It's been in the service shop for a month now. If anyone wants to buy it, I just put $9,000 worth of wheels, tires and 6" lift on it. It looks great but....I have to have a RELIABLE truck.

I traded in my 2018 for a 2021 trail boss.The air conditioner failed on-my 2018 after a few thousand miles. I too had the lifter failure on my 2021 trail boss at about 3k miles. Went to florida and now my air conditioner is broken on the new truck. Was thinking of trading it in but do the 2022 have bad engines, air conditioners and transmissions.
