    I’ve spent more time than I’d like to admit under my truck with my wife working the door, jumping on the door sill, etc, and @wreckdiver I’m most certain you are correct. There are areas under the truck where the sheet metal is stamped together at an angle - with the obvious one being right under the b pillar. That is clearly where the noise is coming from. Maybe a set screw will hold it into place? I have an appointment next week but I’m skeptical that they’ll make progress given everyone else’s issues. I’m bound and determined to solve this.

    I’m becoming more convinced that this noise is coming from metal either under the truck or under the metal near the door sills. Normally the noise radiates through the b pillar, but this morning it was most evident under the driver’s door speaker. @drtyTshrt @sierra1412 have yall received any updates? Has anyone with running boards been able to permanently fix this?

    Did you ever figure out what caused this? Had it happen today and it freaked me out.

    Anyone have an update on this now that it is getting warmer out?

    My 2018 has a similar issue. I thought was under the seat for a while until I could get my wife to drive it. It's coming from the bottom of the b pillar, right?

    GM released a TSB for the Colorado and Canyon #PIT5632 but hasn't provided a fix yet. If you go read some of the Colorado forums, they're having the identical issue. Apparently the TSB was opened in September of 18 and reads: "Engineering is investigating this concern. The root cause has been determined and best path to repair is being evaluated. Attempt no repair at this time. DO NOT put expanding foam in the pillar, this will not repair the concern and will make the eventual repair more difficult. This PI will be updated when the repair procedure has been established." If anyone can provide additional info beyond what's on gm-trucks about this issue, I'd really appreciate it. I love my truck but this constant rattling in the b pillars is awful. Bob - I've had the dealer take my b pillars off and remove the black rubber around the wiring harness. You can see a small gap between the two layers of sheet metal but you can't get anything down in there to see what might be touching. I don't believe you'll be able to accomplish anything by taking the panel off and disconnecting the wiring harness.

    Anyone know how to remove the trim to get access to the inside of the b pillar? Some instructions would be greatly appreciated! Update: Got the pillar off. Definitely coming from the rectangular cut out where the wire harness goes to the door. The post about the two pieces of metal is spot on. Now I’m just hoping my dealer will do the same thing.

    Anyone ever find a solution to this issue that didn’t include spray foam?
