Squirrel in the engine bay?

[ZR2NYC]

We all have it. Some just aren't listening for it. GM is aware of it. It goes away when you disable DFM which is a PITA that I don't bother with anymore. Very pronounced on cold starts and backing out of the driveway, immediately goes away when back into D and accelerating or in L9 since DFM is turned off. DFM is a juice not worth the squeeze in my opinion, but I digress. I have a 100k warranty. I'm going to use the truck for what I bought it for and what GM says it's capable of. If the motor goes then so be it.

great attitude. im doing exact same. the ZR2 has some quirks and yes the lifter issue is not a quirk but im driving my truck like a hot rod with traction control off. the compliments i get zero out the quirks. FYI.....the ZR2 lays an awesome patch of rubber!!!

i forgot to mention that alot of members installed upgraded exhaust systems and louder radios to drown out the ZR2's rat

I'm OCD and notice all the little things. For me, if I spend $80,000 on a truck with a 6.2L V8 with 3 miles on it, I at least expect it to rumble and hum like a V8 with no quirks at all. Not like an engine with a bad AC compressor and worn out belts. That is just how I have always judged the trucks I have driven. I have a very high standard when it comes to vehicles and have always had a V8. The 2008 Tundra 5.7 I just traded in for the ZR2, had 240,000 miles on it. Never had any issues with the engine and it hummed and ran smooth EVERY TIME. I just wanted something new and updated and really liked the looks, features and the fact that it has a bad ass 6.2L V8 in it. Don't get me wrong, the ZR2 is a very nice truck and has some cool off road features (which alot of trucks don't have). And it's brand spanking NEW. It's just that one little thing I can't get past and don't think I can live with, that may be unique to my truck.....the sound of it. I'm taking to dealer tomorrow to let them drive it. I will let you know what they say.

I just bought my 2023 ZR2 and have the same sound. I can hear it while driving, but if I put my ear to the front drivers side tire well, I can hear it good. It sounds like the AC compressor, but it does it when the AC isn't even on (kind of like a ticking sound a belt would make). Does not sound like a clean V8 sound. It's annoying, as I'm OCD. I did not notice this on the test drive. Bugging the shit out of me that I just spent $80,000 on a truck that sounds like this. This is day 2 of me owning the truck and I'm taking it to the dealer tomorrow to get it checked.

yo - feel the aural pain! Let us know what your Service Manager thinks. I''ll bring my beast in for checkup the 20th...

Hello all - anyone notice a chirping / squeak sound from the passenger-side engine bay?
It happens just after cold start - as RPMs drop through 1500 to 1300 range, goes away at normal idle.
Also happens as the engine starts up after AutoStop - for just a second or so, again goes away at idle.
And when driving around with RPMs between 1300-1500, I can hear the chirp/squeak.
I've got the 23 ZR2 - I'm thinking of dropping a round of buckshot into the lower corner to kill that little f'n squirrel...
(btw, that burning brake smell finally went away after about 800 miles!..)

Try peanut butter

Try peanut butter

I'm still betting on the flapper/check valve on the exhaust

Dealer checked out the chirp/squeak: "Belt noise - applied belt dressing" Bullshit. I'll give it another month, then bring it back in. Unimpressed with diagnostic acumen on this one...

I'm surprised they didn't blame complications from COVID!

Any updates on this? Flapper valve didn’t fix the issue for me.
