Wow really. Mine went at 7k. Truck was gone for 3 months and no compensation whatsoever from . Gm
Mine is probably one of the few that haven't blown, but I run mine hard enough to break it in properly. Others put ceramic coatings on them and hike up their skirts to get in.

Everything I drive is a race car weather it really is or not 
I figure the warranty is there for a reason. I dont beat the piss out of it but I do drive it and sometimes to its limits so I know what to expect from it.

A lot of threads on this site regarding catastrophic 6.2 engine failures of some kind. Give the search a whirl, you’ll find more than you care to know. And keep in mind, zr2s are a small subset of the 6.2’s in the wild…go peek at Tahoe/suburban, at4, Silverado, and sierra forums and you’ll find the lifters on these motors are a serious shitshow and have been for years. Seems like new issues with bearings and pistons are cropping up now. My daughters zr2 Colorado is on her third rear main seal at under a few thousand miles, you’re not alone. no compensation seems to be the default as well.
That sucks that they haven't been able to address the seal. The housing has to be out of spec if the seal won't hold. They should just just put in a new transmission.

three rear mains in a few thousand miles, I told them just find a new truck and y’all can figure it out because she needs something to drive. I’m being told, and seems to be validated by others on Colorado / Canyon forums, there was a bad run of parts spring/summer timeframe and it should now be resolved. So far, this one’s held more than a 100 miles or so (last one made it about that long) so we shall see. One dude had five done on his…fundamentals GM, fundamentals.

I had a 20 trial boss 6.2 that used 2-3 quarts between oil changes and they were doing an oil consumption analysis on it and I spotted this ZR2 so I traded in ........I do know their is a class action lawsuit now on Chevy for the the lifters and the AFM system.......I kept up to date on it......I know it's common for them to drop a lifter and break a pushrod.......I always run a bumper to bumper warranty, long as they give me something decent to drive ......let it blow.......and I don't baby it, I don't beat on her, but I don't baby her either.........
mine was at 5622 miles at 2 a.m. on the way to the chesapeake, boat in tow.
called a friend, who owned a GM dealership for 30+ years then retired and sold out around 10 years ago, to see how to handle everything with GM after the truck was in the shop for a bit over a month (was 2 mos by the time i got it back). his statement about the issues all manufactures are having rings truth:
"oatzee, here's the problem: the manufactures are worried about one thing now days, and it has nothing to do with putting out a quality product. all they're worried about is the bottom line for their investors. they're bidding out components, like the bearings that went out of your truck, and going with the cheapest shit they can find. it's almost like they're all seeing who can put out the biggest pile of shit the fastest, they all suck."

It still affects the bottom line with the warranty repairs.mine was at 5622 miles at 2 a.m. on the way to the chesapeake, boat in tow.

LMFAO........ I've said that so many times i should have my own Wikipedia page. People got mad at me and said I was disloyal to GM......WTF....... the GM circle Jerk is alive and well?
I see Stallantis finally canned their CEO and they are hiring back the pervious Ram Division Manager. Maybe they'll finally get it fixed by 2028 models after they flush the 2 years worth of turds they have backed up.

The 6.6 liter in the 3/4 ton trucks don't have those weird lifters and de-activation, ASS.
I think if you can use a 3/4 ton truck this is a good engine to buy. I couldn't use a truck with this much capacity any longer, since I sold all my toys. I'm not sure how much longer these HD trucks can escape the mandates, but for now........
