Angry JK annoying rattling noise - PLEASE HELP!!!

I have a 2015 4 wrangler sport unlimited. When it gets cold out it has the most annoying rattling noise ever start, around or under the driver side back door. It sounds like thin metal hitting thin metal. I have had it at the dealer, where they cant find anything. I have read about the door striker, pillar and sway bar issues but cant find a fix. Its driving me crazy. Here are some videos of the noise...

Find a speed bump and a friend. Go back and forth and try to narrow down where its coming from. Do you have a hard top and are all the bolts tight?

After "Speed!" and "Gravity", I see Sandra Bullock appearing next to Leonardo DiCaprio in "Rattle!"

Oh, and, yes, something's loose back there.

Do you have rock rails?

the squeak could be from your dash...i know when it got extremely cold last month I had a squeak like that in my dash. It was the bolt on top of the dash that holds my daystar cell phone mount that was not tight enough. The clunk when you hit the big bump was probably your driver door. had the same noise. to solve it i put a thin layer of electrical tape around the striker plate.

^x2

Could be a few things but check the heat shield on the crossbar (under tranny). It has 3 welds and those fail often, especially if anything hits it. Easy fix a 2" steel ban.

I have somewhat of a clunk coming from the driver-side pillar where the seat belt attaches to (at least it sounds like that) when I hit a moderate bump. I thought it was coming from that pillar, sound bar area, or even the shock mount. But I haven't really diagnosed it yet.

So you are telling me it could be coming from the driver-side door?
Whats up with that? Any other clunks and rattles I should know about? I just got my Jeep not too long ago.

Thanks!!

Fortunately, you're driving a vehicle with removable doors! If you're suspicious of something in the door vs a heat shield or the dash, I'd start by taking them off one-by-one.

Maybe I'm odd, but I tend to enjoy this sort of problem: fun and rewarding to trace and fix.

My rattle was the tailgate. There is a black vee shaped plate by the striker that guides the tailgate. It is meant to be adjusted. Loosened and moved it slightly, rattle gone.

quality control on these jeeps are not the greatest due to being so popular. Get yourself a torx set and tighten the seatbelt bolts....

I would check the heat shields first as already stated. They will create a loud vibrating metallic noise when the welds break. It is a common issue that has a couple of easy fixes.

Yep, this was my issue as well. I would try adjusting this plate about 1/4" or so.

I can't hear much of anything on your videos, however, I had a similar issue to what you describe, and I was able to trace it down to the stock plastic rear bumper being installed too close to the body from the factory.

There is a small cylindrical plastic protrusion on the back side of the rear bumper (approximately 1/4" diameter and length) that extends toward the body of the jeep (approximately dead center of the jeep and just below the tailgate) and if this is too close to the body then any vibration induced in the rear bumper causes it to hit and produce a metallic clanking sound due to an oilcan condition in the thin sheetmetal.

If this is your issue all you need to do is loosen the two angle brackets holding the rear bumper on and simply pull the bumper a little further back away from the body and retighten. The fastener holes are oversized so there is a perceptible amount of adjustment fore/aft in the bumper.

Took my jeep to the dealer yesterday and they said there was a rattle in my clock Spring it sounded like it was around my gauges and it kept sounding like it was moving around.

I found both my bumper stops were missing on the inside of my glove box door on my JKU, drove me nuts for awhile after I bought it. Now , why would there be no bumper stops on either side of the glove box door?? kids, I guess..
