I have a 2019 cruze 1.4 liter turbo engine with only 10,600 miles on it. The engine light came on so I took it to the dealer and according to them a piston is bad. My question is it ok for them to only change 1 piston instead of all4 ?

Thank you Maven for the reply. This document #5080870 where can I find it and read it? Is it a GM document?
Its a GM TSB. #18-NA-171.
I usually don't just give out TSB #s because honestly....customers who come in with TSBs are annoying as fcuk, and piss me off. LOL.
Referencing the document ID will likely get you taken a little more seriously and not just like someone with good Google skills. You'll seem like you have someone inside.

I'm a Chevrolet dealer technician, and I can safely say the correct repair is all 4 pistons. It won't cause 'more stress' or damage other parts of the engine, however a couple weeks ago I rebuilt the engine on a 2020 Equinox, that jettisoned half a fragment of its piston through an exhaust valve, which smashed the valve too. The problem is, the piston doesn't just 'randomly' fail. Something caused it. Whether it be a casting defect, or the engine inhaled something to cause that catastrophic failure, whatever damage was done to cause that failure, could be present in other pistons now.
Also, some food for thought, at that low a mileage, any failure of major drivetrain components is the reason the warranty is there - Mass production can cause defects. And as demonstrated above, both causes for such a low mileage failure could have happened to any car. It just happened to be your car. You have no 'good' reason to be pissed off. GM will repair the vehicle at no cost to you, the dealership should put you in a rental for the amount of repair involved, and your car will get a 'reset'. The Cruze had a lot worse issues in the 2016/2017 MY's, where it was ALWAYS Piston #1 that cracked, and then if they experienced it again after the ECM recalibration, it was #4. At this point, that issue has been ironed out, as the improved pistons and ECM calibration are on all those Cruzes.

I had similar issues long time ago! I didn't let them change only two pistons! I told them I'd even pay for these (I was under warranty) but I will complain about this since if half of them failed then it is a high chance that the others to have small cracks or damaged already. Finally they did replace all free of charge, as a "courtesy". Honestly, don't let them change only one even if you would pay some extra...
Just in case anybody else was unclear, putting new pistons, rods and rings in a used engine that blew up doesn't make a new engine, or do a kind of reset....
GM doesn't replace the engine because it's cheaper to just replace the pistons. If a cylinder wall gets damaged, you'll get a new engine. But not just for a broken ringland and no extensive collateral damage

Shroomie, make no mistake, I fully understand that things made by man can made wrong, fail early, etc...I accept that, a large portion of my income is based on that reality.
But that doesn't change that many people get upset when things break or fail early or unexpectedly. And telling them they have no right or good reason to be upset is absurd

Well there's the first problem, many people do take offense when others offhand assume they know nothing. You assuming that you always know more than who youre dealing with and talking down to everyone as a default is a sh!t character trait and something that you need to deal with, grow up (regardless of your age) and deal with people on a reasonable level.
I realize you're lashing out a bit here as I've shown that I'm not someone you can intimidate with your knowledge/experience, but its pretty clear I don't have photos ready to go.
I thought you were a used car tech?
yes, it CAN take weeks for parts, it typically does not, and definitely not recently in my experience with the LE2 pistons, even with COVID and the strike last year, these were pretty readily available parts lists. to tell people who you think know nothing that it takes weeks to replace pistons is misleading at best.
Hope your Equinox wasn't a 1.5, cylinder head machining isn't allowed on them
Not reusing anything, ever, again leads me back to my thoughts on being naive, and not taking care of your customers. Nevermind the fact that Ive yet to meet a shop foreman/shop manager, or service manager that would allow that type of delay for something silly. This also means there's likely an issue in your parts dept too, as any good dept would be doing everything they can to get parts in. and keeping customers in loaners/rentals for weeks isnt something GM likes to do.
As to getting chargeback for not having enough parts on the repair order? ROTFLMFAO. I've never once seen GM bounce a claim because there were too FEW parts claimed. they dont give a f#ck....if you say you fixed it and it cost less than what they expect it to, they are happy as hell. I've seen LML diesel fuel system rebuilds get paid with no injector/pump kit billed out!!! No if you have ONE extra bolt, or seal on there, you can rest assured they'll bounce it back and make the administrator resubmit with less parts before they pay.
Do you realize how many perfectly functioning Cruzes are out there with reused bolts? my guess is honestly....virtually all of them. And I'd be willing to wager if you were honest, you'd admit that you've shipped cars with reused parts too.....every cruze brake job you've done got caliper bolts?....come on.
Yes, you're right, it's better it happens under warranty than out of pocket, but to tell people they have no right to, or even shouldn't be upset is silly.

I recently bought a 2018 cruze in March and immediately put an extended warranty with patriot auto warranty last week I had 2 pistons go out 1,3 after a week of run around with the warranty company they denied my claim because of the gm 18 NA 17 bulletin. The dealer wants 6800 for the repairs how can I get gm to cover this my car has 104k miles
The after market warranty was bumper to bumper with all components they denied the claim because of gm bulletin
GM-18- NA
GM-18- NA
According to the bulletin it's on the 18s there's a update on the ecm for the 18. The bulletin was also for a few other models as well.
The manufacturer warranty was 100k and the extended warranty was for an additional 100k but the extended warranty is denying the claim because of the gm bulletin.
Jasper is a motor reman company. I know of several friends and family members who have purchased their motors for vehicles. As far as your warranty situation is concerned I would quite possibly contact an attorney.
