I have a 2021 crew cab 2500 hd with 29K on it.I have been to Robertson GMC for this issue, door sounds like it's not shut. They said there is nothing wrong. I was told they adjusted the door and it is correct. Now I have lots of road and wind noise. I can put a dollar in the door opening, close the door and slide the dolllar out like its not touching. It's so annoying that when you go over railroad tracks or curtain bumps the door rattles like it's not shut all the way. I've recorded it and you can hear it in a recording. But the dealership said nothing is wrong with it. Now, it is getting alot worse and the other door is acting up. To compound this issue, I am experiencing a vibration at highway speeds (70 mph on cruise control), I'm so Frustrated and Disapointed in a truck that I saved a ton of money for. I feel like I got ripped off. Please GM do something! I dont want to send my truck in just to be told it's supposed to be like that
