I cant find it in my email anymore. All i did when I posted the claim was to just tell them about the problem we all are having. I suggest we all do the claim with the state AG.

All right guys I filed a claim with the state attorney general and GM called me and basically said what do you want us to do to fix this issue so I urge everyone on this thread to file a claim with your states attorney general for this exact issue as I told GM I’m not the only one who is experiencing this issue if we get enough people filing claims with the attorney general’s for each of your states I am positive GM is going to address and fix this issues ASAP. It’s really easy to do online.

I did the innertub trick last night and seems like the noise is gone. Thanks for the help!

I filed a complaint with my states attorney general. Yes they re torqued the springs and that didn’t fix the problem. If anything the thumping is louder than before. I agree I a I’ll be persistent and keep calling GM until I get this issue resolved. It’s absolute bs.... guess they don’t care about keeping customers

Same issue here on my 17 Sierra Elevation edition. Took it to the dealer twice first time lubed the leaf springs did nothing. Second time said it’s coming from rear diff and called GM and they told dealer it was normal and nothing needs to be done. Said that trucks always made that noise and it’s just the cab is so quiet now LOL! Explained I’ve owned trucks in the past and never had that noise. Then called GM and the incompetent prick basically called the dealer and told me that I’m SOL because they say it’s normal and nothing g can be done. It’s so annoying when I’m driving at low speeds I can’t stand it. Can someone give some advice on the leaf springs with inner tube idea? I will try that and see if it fixes the issue. I agree a class action lawsuit may get GM to buck up and stop being cheap about fixing a brand new truck. We pay far too much for these to have issues at 25k miles!! Let me me know about the leaf springs but mine is when you push on the back rear of the truck it’s a thumping/grinding sound... may be rear diff, may be leaf springs not exactly sure
