2022 6.2 engine failure.

Texas_Toast · October 10, 2023

Well, this one is a first for me. First engine failure on a low mileage/warrantied daily. Have blown up lots of hot rods and toys, nothing stock at 15k though.

Was on my way home from hunting, coasting down from 75mph(spd limit) to 55 to go through a small speed trap town. Heard some abnormal noises under the hood, was checking gauges/lights when the truck just died and shifted itself into neutral. Luckily I was able to coast it into a feed store parking lot without getting ran over. Dealer says its not in the valvetrain, something on the bottom end. There's 4 other 6.2's in front of mine that they are tearing into the bottom end. All have the same symptoms.

Popular reading online is blaming the rod bearings on 22+ 6.2 vehicles, not isolated to Silverado/Sierra. Hopefully GM is has already changed suppliers but who knows. No timeline but its looking like I'll be driving the 2wd loaner for a while.

That sucks big time.......

I have a 2023 High Country with the 5.3L........wanted the 6.2 but none available in my area in the color I wanted.

Maybe glad I got the 5.3 after all.

Please keep us updated on progress.....

Bad deal. This on top of lifter failures caused by DFM.

I will be following your situation.

Our sister store had 2 6.2s go a few months ago, both under 10k miles. One a Yukon Denali, the other a 6.2 Trail Boss. Both 2022s.

Service tech is telling me it isn't top end at all. Which worries me even more.

Several 6.2's in front of mine with bottom end failures at a large Houston based dealer. Not sure how that scales with the general population. I was reading the yukon/tahoe forums and there seems to tons of 6.2 bottom end failures. Theirs were all spun rod bearings.

So, my Silverado is a 2022 6.2 with about 21,000 miles and has been at the dealership for 1 month now.

The motor started making all kinds of noise that I thought was the lifter fail, but after watching too many

videos on youtube I suspect it has spun a rod bearing[s]. Dealer tells me it will be covered but is still waiting

on GM to authorize repair or complete replacement of the engine. Pretty bummed out and don't feel optimistic

that I will get the truck back anytime soon. At least they gave me a brand new truck as a loaner lol!

Sure hope they sprung for a rental car if they are still sitting on their hands after a month.

Yeah the 3,000 mile 2wd they gave me is nice but its not my 4wd High Country during deer season nice lol. I wonder if Onstar will come get this truck if I get stuck? Haha

Got a low mileage dealer loaner but can't drive it out of Texas due to ins reasons. Sucks because my best customers are in South Louisiana. So took the wife's Kia K5 GT....which hasn't had any problems(listening GM???) to see my customers this past week.

My 22 Refresh Denali is at just under 11K miles. This doesn't give me a warm and fuzzy feeling before driving it from Pa to Maine next week.

Texas_Toast · October 24, 2023

Horrible experience with the dealer today but that's because they tried to deceive me and then outright told me about it. Then they were extremely rude for no reason, I was mad but kept my cool in front of them and buried it down. 6-12 months is all they can tell me. GM will cover a Hertz rental....a Honda Passport, minivan or v6 Camaro. Because apparently I drive to much to have a dealer loaner truck. I'm not suburban soccer dad of the year, I spend my 4 weeks of vacation and at least one weekend a month on my family's 300 acre mini ranch using my truck as a truck and use it the absolute most during deer/duck season(every single weekend). I actually use the truck as a truck.

They were a little mad I forgot to wash the doe blood out of the bed. They didn't see it until I was leaving to go to Hertz. Proceeded to tell me I shouldn't put animals in the bed, told them the rulebook didn't say anything about dead deer in the bed.

Will be calling GM tomorrow to see if there are any options for a buyback including down payment. Should have followed my gut and got the LT Duramax or 6.6 gas.....or just stuck with Ford. We'll see what they say. Not being optimistic about it though.

I will try to avoid this dealer through any buyback that may/may not happen. Not sure if that's possible though.

matt450exc · October 24, 2023

That sounds pretty crappy Texas Toast, I feel your pain. I just got off the phone with GM customer service

asking me if I have heard back from my dealer with any new info (I haven't since I contacted GM). They will be

replacing the engine, but are waiting on authorization to order it. The auto workers strike is also making it more

difficult. I fear we will be without our trucks for a long time.

Here, I was thinking. I had all the bad luck!! Sounds like bottom ends in these 6.2L's failing is more common than what the dealers play out to be... I've now experienced 2 bottom end failures that have both resulted in long block replacements. I'm sure glad we purchased the extended warranty! Truck currently has 72000km 1st Engine Thrust Bearing failure @ 44000km 6 weeks in a rental.

2nd engine 28000km #1&2 Rod bearing failures with no eta on a long block..

Has anyone had luck with GM buying back their junk? I've lost all faith in the 6.2L and want to get into a one ton Duramax. I dont feel i should have to eat the financial loss having to switch..

I do love my Trailboss and wish I wasn't having such terrible luck.. fool me once fool me twice call me stupid if it happens a third time...

matt450exc · November 13, 2023

Small update. Chevy finally gave the go ahead to replace the engine ( I thought they already had done that) two months

after I dropped the truck off. They requested the dealer to tear down the motor just last week to look further into it. Why did that have to take nearly two months?! The service writer seems to be just as frustrated as me with the way Chevy operates with this warranty work. So we will see how many more months it will take to actually get the engine in and the

truck back! Ok rant over.

Just wanted to post some updates.

Got the truck back first week of December. Dealer rebuilt the engine. Truck seems to run good, except for anything Onstar related. The module apparently went out while it was at the dealer for two months. They're on backorder.

Truck did seem to run just like new though. Same mileage, good power. Took it back in for a couple of days for them to diagnose the Onstar issue. Truck runs and drives, but gas mileage suddenly went way down the drain. Ever since I picked it up my HWY average has been around 14mpg not towing. That's what I used to get towing my SxS down the highway. So now the dealer wants to look into that. I love taking the truck in for one thing and something else breaking/goes bad while its there. Quality at its finest.

I'm on my 4th GM customer service rep. After being promised a buyback, seems like they are backing out now. After multiple people have promised me a two month payment reimbursement(something that was originally offered/mentioned by them). Now they are saying that will be denied because I was given a loaner from the dealer. When I had a loaner dealer truck for less than a week and then was put in a soccer mom Hertz rental crossover. Which to be clear.....IS NOT A TRUCK. It would not tow my horse trailer, my boat, my SxS and I couldn't use it around the family farm. Which is the exact reason GM originally said they would give me a two month payment reimbursement. I've requested all the phone call recordings from my conversations with them. Doubt they'll give them up.

This will definitely be my last ever GM product. I understand it was a random engine failure and covered by warranty. But the way the dealer has handled things and the way GM has directly lied to me and made fake promises just puts a bad taste in my mouth. If you can't/won't do something, that's fine. But don't promise me steak and lobster then give me a plate of horse crap.
