That's disappointing.




Well make sure you register your complaint, call often, and hopefully they come up with a resolution soon.

 

Yes, mine started about two months ago on 2021 Suburban RST. It’s louder now that it’s cold out. It eventually goes away the more you drive it. Been to the dealer once only for them to say they couldn’t not duplicate. Back to the dealer Monday. Differential is full of oil.

 

My 21 has the same issue. Dealer had it for a week. They heard it, but could not diagnose it.
They also changed some fluids. The noise has been getting worse.

 

Any fixes, mine has been in shop twice, they sad could not replicate. Left for a week when out of town, was able to do it right away. Anyone got a fix to this issue yet?

 

'21 Z71 Tahoe with this issue .. getting louder as it's colder out now.. getting ready to call the dealer for an appointment.

 

Hello All,

Hoping all is well. My 2021 Tahoe LS started doing same noise/rubbing when turning but goes away after couple turns. Tried to replicate when reversing but doesn't. I took it in to dealer and they couldn't replicate. They instead found other slight noise in engine and replacing minor thing however I asked them that when I go back this week I want to drive with the tech no that I can hopefully replicate and he or she can hear it. Any suggestions or what outcomes you all may have had are appreciated. Kinda frustrating to be honest, I'm sure you all share the same sentiments. Thanks.

 

Bumping this... I've had this looked at 3 times and they could not replicate the sound and suggested I leave it over night. Which of course is hard to do when you NEED the car. Anyone else get this resolved? Only happens when the car sits for X period of time and its colder (I am in Florida)

 

I am in West Palm Beach Florida and going Monday to get this looked at - really annoying - will be driving with tech to duplicate as they seem to not hear, it its crazy. Hopefully it is only the lube in the differential because seriously thinking of trading it in, first the lifters and now this. It's too much for a 2021 tahoe with only 33,000 miles.

 

24,000 miles for us. Only happens in the morning or when the car has been sitting for a while. Let me know what your tech says. My appointment isn't until January 9th....gotta love how getting service appointments are always so far out now.

 

Look what I found!!!!!!
