As of today 2/7/2023 to summarize, First, there was a fuel leak Second, after the tire rotation you simply cannot hear anything when traveling between 55 -61 mph Third, had an oil leak Fourth, I have a DEF leak and the dealer said it was normal! Normal?? I have white crystals all over my garage floor! This is a joke. Melbourne , Florida TASCA GMC. Is this where we are at in America today? A new $60K truck with this many issues?? GMC should be embarrassed.

Wow! Thank you all for the information.

Sorry, forgot to add its the 3.0 diesel.

I have a 2021 1500 AT4 with 28K miles on it. Everything was great until the first oil change. They rotated the stock tires, and when I drove home, at 57-60 MPH the tires mad such a bad noise you could not hear the radio. I drove it around for a week and took it back and had them change the tires back to the original position. The noise went away. Now, as I need a new oil change, the tires have started making the noise again. At roughly the same MPH 57-60. It's really bad and not pleasant to drive. Has anyone else had this problem? Any ideas on what to do? Thank you. As a side note, on the first oil change they found a fuel leak in the fuel hose. Had to replace the entire assembly.
