2023 Tahoe/Squealing at low speeds

[GoNoGo]

Honestly, I feel for you and others with that squeal noise but I’m extremely pleased with my ‘23 6.2 Burb and don’t want to become depressed after going on a Witch Hunt to then actually discover a problem that I was previously happy NOT KNOWING that I had.

I sincerely hope you can relate

Complete understood.

My Yukon makes a similar sound. GM has a bulletin saying it’s normal for the 6.2. See https://static.nhtsa.gov/odi/tsbs/2022/MC-10225749-0001.pdf

There is it.

I guess I'll just drive in L9 from now on until I can find a replacement vehicle.

Just noticed @Deuce16GMCs that you have a 23 Tahoe. I bought Tahoe 6.2 HC with air ride adaptive suspension in Jan and did not care for it as compared to the identically-equipped Suburban that I got the previous month.

The Tahoe had an irritating drone/whine coming from the transmission or rear area between 40-55 mph, like a bearing or rubbing noise. Also was not as smooth-comfortable (as Burb) on my local rough pavement and washboard gravel roads near my house.

I *think* the whine would've distracted me from hearing any cylinder de-activation squeal, but anyway.. I kept the Tahoe for 800 miles and traded for another 23 Burb HC with duramax which is the only powertrain to have IMHO

Just a follow-up. My job uses Escalades to transport guests.

Today I drove 5 Escalades. 4 had zero squeals. 1 squealed so low 1 time that I had hang for the vehicle to hear it.

This is maddening to see such inconsistency and lack of quality control from GM.

I just saw this thread and a part of me just died. I have a 2022 Z71 6.2L....

I have squealing noise on my 2023 Escalade. Really annoying.

If you open the hood and have someone hold the accelerator at about 2000 rpm’s constant you can hear the squeal.

Man...I'm miserable. I love this truck. My kids love this truck. My wife loves this trick. But this this squealing is horrible.

Iits in the mid 70's here and I can't drove with the windows down.

It squeals when stopping at 14 miles per hours (this one can be cancelled by driving in L9 to deactivate the DFM).

It squeals during every gear shift (regardless of L9).

It squeals when accelerating from the mid 30's to mid 40's (regardless of L9)

It squeals when cruising on the highway in the low 70's (regardless of L9).

I wish I had never heard it. It's horrible and and getting worse.

The squealing while shifting, accelerating, and cruising are not part of the "squeal bulletin".

And the dealerships don't care to attempt to fix it or identify it.

I'm at a loss for words here. This sucks. I can't believe anyone would think it's normal.

I waiting 9 months for this truck. SMH.
