I just bought a 21 Silverado RST and About 4 months after purchasing it I have started to notice a rattle/squeak coming from the driver side door frame. It is extremely loud. I have tried shaking different pieces of plastic but I have not been able to recreate the noise. It only happens when driving over bumpy roads. I am wondering if anyone else has experienced this and if so, were you able to find the source of the noise? I am assuming it is a piece of plastic that needs to be tightened.  Thanks.

Also, check your hood release.  Mine started rattling within about a month of ownership.  It just needed a simple tightening.

The hood release inside the truck or under the hood?

Thanks, I will check that, but the noise sounds like its coming from outside the driver's door.

Did you ever figure out what was going on? I have the same problem!

Mine is the drivers side mirror. It’s apparently two separate plastic pieces and one is just loose enough to rattle in the wind

Mine sounds like the mirror also, how did you fix it?

I haven't yet but it's annoying me more and more every day. I may get the body colored mirror caps and see if replacing them fixes the problem.

Any updates on this? I’m having the same issue.

Just bought a low mileage 21 LTZ and I had the same annoying rattle at the driver side A Pillar. Mine was a small piece of plastic held in with 3 small push tabs located on the door just below the side mirror. Put some 3m adhesive tape on it and reinstalled…problem solved!

Well…my problem turned out NOT solved 😟! So this weekend I went at it again, keep in mind I had already secured the hood latch cable under the hood and in the cab, taped the mirror plastic up so I could check that off, same with the moulding strip on the cab and the black plastic piece on the driver side cowl. All this plus the stuff in the post above related to the inner door plastic!!!! 
Thankfully persistence paid off!!!….something told me to look lower so crawled under the truck just behind the front wheel and discovered that the front mud guard had a tab on it that was not installed properly!!! I was wondering it this could possibly be it….so I pulled 1 10mm bolt out and replaced it so that it held the plastic tab in place. To my pleasure I’ve driven 75 miles and not one sign of the plastic rattling I was hearing that drove me bonkers!!!

hope this helps someone!!

      I am sure that was quite the pass experience and not a great place to experience during the winter when the conditions are not good. I've seen video of that pass and also more detailed information and pictures about the wrecks at that one hair pin turn where tractor trailers have flown right off the cliff and I am sure from all the warning signs that you know the exact curve that was !. After all there is a reason why a song was made about Wolf Creek Pass !. By the way and I didn't realize this either when I bought my truck as its nothing I even thought of that would be programmed into the cruise control and this occurs in either the basic or the more advanced cruise that controls your distance behind a vehicle and that is the brakes going down a hill are being applied as soon as the vehicle goes a certain speed over the set cruise speed. While it certainly does force downshifts in the transmission as you found out with cruise on while going down hill, its also dragging the brakes as needed to keep the speed controlled to what the cruise was set to. For me, I find that unsettling simply because I have no concept then as to how MUCH brake input is being used a and just how hot are those brakes getting and the wear factor as well. I can see that system getting a person into trouble on long mountain grades while pulling a trailer as it would not only be standing on the brakes of the pickup without any driver input, it would also be automatically applying the trailer brakes and it could cause a run away unit by overheating the brakes. Its one thing on a shorter hill and if the driver allows it to do its thing but on a long mountain grade is where things could get so out of hand. As someone a while back on this forum said, they had someone following them at night I believe on a down grade and had the cruise set and the person behind them could see the brake lights being energized all the way down the hill. I figured when I saw your comment that you didn't know and would have no way of knowing that your truck was applying the brakes and that you would and rightfully so assume you only used the brakes when you pressed on the pedal to slow down more than the cruise set speed for the slower sharp curves. So its good knowledge to know this about the newer GM trucks, certainly when doing any descending on long mountain grades. In the future try kicking off the cruise and use the the manual mode on a pass to see what that is like as I know myself when I first experienced it I thought no way can this engine be holding me back this well and tried the same hill in manual mode and sure enough the engine was revving way up and still could not hold the trucks speed down like it could in cruise mode.    Fuel mileage, that is where a really low sleek type of car can do better at higher speeds, certainly it starts sucking fuel too but a tall pickup is pushing massive amounts of air and also allowing a lot more air under it and the tow mirrors as in elephant ears pushing through the wind  as well. Driving like grandpa is about as good as one can do when driving one of these if trying to get the best fuel economy they can. I bet these trucks would get the best mileage they can if driven on a freeway in Florida if not busy traffic at a sedate speed and that sea level elevation without hills, vastly different then Colorado !.
