I know I'm going to get ripped for this, but the same problem on the L87 6.2L V8 was also apparently corrected after 24. Yes, I know they are different engines. Same suppliers for certain components though?

That being said if you've got warranty coverage just make sure your oil level is always good and use this thread if someone tells you it's an 'isolated incident'

I've not heard of any engine failures though in the 2022-2024 Camaro ZL1.

Anything manufactuered after 2020 is suspect at this point due to the post-COVID supply chain crises. We still haven't fully recovered IMO and the failures happening in the LT4's and the L87's are absolutely connected in one way or another. Given the very low production rate of these cars, I'd also say the failure rate is definitely above average just by looking at this thread as a sample size. Hell, even C&D's test car which they had for 40k miles blew up.

Not good.

Agree to disagree, there's literally 30-40K of these engines out there in various platforms and we only know of a few failures here on this forum and there have been some in the 2017-2018 Camaro ZL1 because of a known oil pump issue which is also avoidable if the oil pump was replaced under warranty. Those press cars are beat the Hell and back, we don't even know if it had proper maintenance.

I still believe the failure rate is stupendously low for these engines but it appears at least based on this thread that vast majority were 2022-2023 cars. Makes you wonder if there weren't some minor changes in the 24-up cars or if there was a bad batch of engine parts in a small number of cars.

Funny thing is there were less issues in 2022 engines. 2023 seemed like a bad run for engines and constraints on parts.

ZL1s were still mostly the first 2 years, which is weird considering 2016/17 CTSV had no oil pressure issue and theyre the same wet sump engines.

That is interesting, I didn't follow the CTS-Vs at that time, I had always had Camaro's and Corvette's prior to my Blackwing.
 
A handful of engines ate plugs, which created the failure over an internal failure, ie crank or lifter failure.

On the L87 comment, I had a 2022 GMC AT4 with this engine. I proactively switched to Supercar 0w-40 from 0w-20 and it got quieter. Oil pressure was improved under all temps. After it passed pico test with 0w-40 (never told the dealer before the test) they claimed good engine. I had 20k miles and decided in Jan to trade to another brand because I couldn’t “trust” the engine. To be fair, the engine never failed me, but I hated thinking about, and shouldn’t have too.

I just got pissed with the way Mary Barra is handling the whole situation. She’s a lying terrible leader and could give a rats ass about any of us.
So, I will not spent anymore money with GM at this time, and while I know every brand has problems, for me, it starts at the leadership level and how they handle. Many owners of those engine have waited months for replacements.

I still have my 2022 5BW and plan on keeping it. I only have 1855 miles, an extended warranty, love the hell out of it, and in the future after warranty if I have an engine problem, I will and can rebuild it myself. I also have two other LT4 vehicles with no engine issues (2016 Z06 & 2017 ZL1). Both have more mileage than my 5BW, and both have separate non-engine related issues, but I have accepted.

When I retire in a few years, I figure I’ll have more fun cars to choose from.

I used my GMC as a so called daily and airport vehicle when I travel. I purchased a 2026 BMW X5 sDrive40i. Living in the Houston area, I don’t need AWD, and instead used the money saved towards the options I really wanted. Also, less/cheaper maintenance with 2wd. I got 12% off msrp, so happy with the discount on a quick depreciated asset, lol.

Having an X5 xdrive 40i in the family, I would never get into that BMW trap again. The tire depth balance requirements and that transfer case....... Man, never again. sdrive all the way.
 
There haven't been reported engine failures for any of the 25-26 models?

It appears the majority were 2022 models and some 2023 models. Overall, the numbers are still very low.
 
Can add me to the list, perhaps for two motors if you count the original motor.

Had engine placed due to excessive oil consumption (1 qt/<500 mi). Scope showed scoring of cylinder walls and GM decided to replace it (28k miles)

Replacement motor died at 500 miles. Wrist pin apparently failed and caused rod/piston dissociation.

Second replacement doing well so far at 350 miles.. hopefully no other surprises.

What year car?
 
I saw on one of those car tv shows where they had a brand new Escalade with the 6.2 engine and it also had a "wrist pin" failure that went catastrophic.

I literally just added 2 quarts of oil for the first time in 26K miles when my "low engine oil" light came on. I'm hoping it was a one time thing due to the intense Phoenix summer and my spirited driving in the said weather.
 
I have a 2022 and only have 9300 miles on it. I have already done 5 oil changes on it ! That averages out to an oil change every 1860 miles ! 6 months every winter , she sits in storage from November to April. Someone is going to get a well maintained and kept car when I sell it ! I have had it 4 years and I haven't even done a smokey burn out with it !! Yes, I know....I should be ashamed of myself.
