I'm having the same squeaking issue with my 2020. Glad to here that there is a TSB regarding this, since I was wondering how there could be an issue with only 6k miles on the vehicle.
I'll have to schedule a service for them to correct.
I did the same thing, but I went from a Silverado to a Sierra.
Originally had the 2019 1500 pulling a 1963 26' Airstream, no problem whatsoever. But when we sold the Airstream and picked up a 34' Travel Trailer, the 1500 had to go. Picked up a 2020 Sierra 2500 AT4 gasser back in September.
The AT4 pulls our new camper like a dream. You forget that it's being towed until you look back in the rearview.
Everyone always comments that it looks black as the sun sets. I love the color and am glad that I passed over one of the red trucks that the dealership had.
Hi Everyone,
Here's my new toy that I picked up in late September. My 2007 Avalanche started to have some challenges, so made the jump to a 19 TB LT. Love this thing!!
