The initial call in for service it was taken in on 12292020/mileage 1020 for a oil change and a clunking noise coming back from the rear end at low speeds, while turning and going over bumps at all speeds. The dealership was able to hear the noise and advised that they cannot find out where the noise is coming from. The dealership advised that they submitted a ticket to GM for the noise. On 03022021/mileage 2797 the truck was taken back into the dealer for the same noise because its getting louder. The dealer again said that they heard the noise but cannot figure it out. They advised that they submitted another ticket with GM waiting to hear back from them they closed out the ticket on 03102021 with no answer from GM. I have also called GM customer service and spoke with on 03102021, and told me to call them back because they had to try and let the dealer resolve the issue and the dealer is waiting to hear from GM. The dealer did advise me that there was a service bulletin for 2020 Chevy 1500 pick ups but nothing for 2021S so they can do nothing yet, the sound sounds like to me that the axels are going to come loose or the suspension is going to drop. I am afraid to drive the vehicle fearful that something is going to come off or the suspension is going to drop if I attempt to tow something. Thus causing pain, injury or death to myself or another innocent party. I am considering taking it to another dealer again to see what they say, but I feel this is safety concern all people who are hearing this noise on their 2021 Chevy pick ups. I also would like to add that this truck has no suspension modifications of any type and is all stock. Thank you for taking the time to look into this. Also attached are the work orders from the Chevy dealership. Thank you again

When the truck is put in reverse the back up camera becomes very 'fussy' an unusable. The only happens at night when it is needed the most. The back up camera provide no help in fact maybe dangerous.
