Also having the rattle in my at4. Seems like if I pull back towards me on the center dash storage tray it seems to go away. Does this sou d like the rattle of the ducting on the bar?

I am have a similar rattle and pulling the tray helps my High Country’s “popping” as well. Any other suggestions as to where it could be coming from as I have a hard time understanding how pulling on the dash/tray could help with the ducting bar.

My AT4 does the exact same thing. If i pull the top center storage pocket towards me it goes away. If you move it back and forth you can hear it squeak. Very annoying. Took it to dealer with no solution. Dealers do not seam interested in working on this type of problem. Would love to know how to pull the instrument panel and get to the ducting to see if this would fix this.

I recently partially took my dash apart. I ended up taking the top tray out and the front windshield defrost grill out. The defroster grill pops out with a plastic trim tool. The center dash tray does as well once the single screw is removed. While reinstalling the screw in the dash tray I pulled back on it and tightened the screw. I then popped the defroster grill back in, the rattle seems to have stopped. At least for the time being. Now the center console squeaks of course.

Just found my rattling noise on my 2020 Chevy 2500 6.6 gas. The antifreeze reservoir, was loose. 

You're the man! I was just about to start digging into the dash until I saw this post. This ended up being my issue as well.

Hey, little late into the game.  Just bought a 2021 GMC Sierra AT4. I have the same rattle: so far I have removed the cluster and added rattle prevention to the AC duct. I have firmly secured the hood release pull cord all the way from the inside to the hood latch. This rattle is driving me insane and the dealership (despite have a new vehicle warranty) charges me $150 anytime I bring it to the shop with this issue. They claim its a harness loose but do not know “which” one or “where”. Any solutions would be MUCH appreciated

Edit: The coolant reservoir mentioned above was missing a bolt. After bolting it down with felt washers on both sides, still no rattle solution.

FOR THE LOVE OF GMC, the rattle has been found and fixed. One of the screws holding the fender well up was missing. The metal clip that sits in the metal bracket got wind on it at higher speeds. Put a piece of tape over the clip and a new screw in it. Wallahhh.. no more rattle. One key point that made me look there was: the rattle went away even at high speeds when it was raining. The weight of the water on the clip and fender well prevented the metal on metal rattle at higher speeds. I’ve got a video of what it sounded like for anyone hunting a sound

      Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles.

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
