Driver side plastic rattle

[wisconsin1259]

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.

Check that sun visors are clipped in.

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

I have a 2021 RST and have the same issue, mine started a few months after I got it and it's driving me nuts trying to figure out what it is,

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!

No, I did not.

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?

[tpettigr]

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!!
