Any updates from anyone? It sounds like my "squeak" is getting louder. Currently around 2600 miles. I did have a CAT back from GM installed to try and drown out the annoying squeak, but it didn't help. At least the good news is, the exhaust itself sounds awesome.

GM sells a wireless keypad to lock and unlock the truck. Its 125 bucks and has 2 way tape on the back. Mount it inside the fuel door- too bulky to stick on a door. Lock truck with fab inside.. use keypad to unlock when coming back. Outside of 3rd party work arounds, that would be the cleanest fix i can think of. https://www.shopchevyparts.com/electronics/2019-silverado-1500-remote-keyless-entry-system-keypad-433-mhz/23473341-p-92300642.html

Any updates? I’ve been waiting to return to service hoping there would be a solution.

It will be interesting to see what the solution is. Not the end of the world, but irritating on an otherwise perfect truck. I did use the squeak as an excuse to put on a cat back. Still hear the squeak, but now there is a good throaty exhaust behind it.

Hoping a solution is found... the 6.2 qand 10 speed is an awesome combo. The squeak is mild, but not the typical type of noise id say is acceptable. Im having a cat back installed next week, ill see if the dealer can take a second look. From what i could tell, it was exclusive to the passenger side, and seemed to be coming from either the exhaust manifold or potentially the o2 sensor just down from it. Could even be a heat shield thats rubbing when the engine is at the right rpm range causing a vibration. Troubleshooting shouldnt be too hard, but i was by myself. Need to jump the rpms to the 1200 range once warmed up.

I’ve got a 6.2 hc with same issue on startup and cruising at same rpm range. Dealer said they didn’t hear or couldn’t replicate sound. Let us know if anyone finds a solution. Sounds like a pulley or even a small exhaust leak on passenger side of engine
