2024 At4 down

[EEAT4]

I hate to join this group in bad news. but my 2024 AT4 left me on side of the road yesterday . I was driving to the lift shop to install my 4” BDS lift kit. I heard some knocking and than less than a mile it just shut down. I was able to restart it again and pulled to the side . But than it went completely dead . Had it towed to dealer , waiting on diagnose. But now am worry that am stuck with a broken truck and lift kit that I can’t return . Truck was bought in October and it has just under 3k miles

Keep us posted. The good news is it's still under warranty. I can't quite read your fender badge, do you have the 6.2 or the 3.0?

6.2L?

Badge says V8. Is the 5.3 available in the AT4?

Nope, not on the 24's. 6.2 it is then.

Damn, I'm not looking forward to hearing his outcome.

I've heard chatter on a few different forums about loosing the bottom end on the 6.2s, I think there's a guy on this forum who said his wife's 6.2 seized with something like 40k miles on it.

It’s V8 6.4 . Not really a straight answer as of now. But they did manage to give me a loaner Car. Am staring to worried. I attach a pic of the message they left me

My 2022 at4 6.2 seized with about 5k miles on it. They swapped a whole new motor in and it's been perfect since. I have 30k on it now.

Been having bearing issues on the V8’s bub - known issue on a batch of engines across all GM vehicles lines. Spoke to an UBer driver that said it’s happened to a few of his associated even on the Cadillac Escalades. Hope as other poster said - it’s under warranty and will get corrected.

That's disturbing news. I had a 6.2L on my 2018, and I just purchased a 2024 AT4X with the 6.2L motor. The 2018 was a great motor - no issues, great fuel economy, etc. Keep us posted on how this unfolds.

Finally got truck back. Seems to be running good. Here is what was wrong with it …

That is some great detail from the service tech - glad it’s back. Check hoses and gaskets for leaks or issues a couple times over 1000 miles. Hope good stays good and thanks for sharing the detail.
