Yep that’s what mine looked like too. Blew my mind lol.  Although with mass produced items it really shouldn’t anymore.

Wow that’s scary honestly yea your right I guess it can be an assembly line issue. My first thought was the wonderful dealer techs lol I found the pic I was gonna bring to the dealer the next time I go lol. . cd90965ab3d3abd639edc6c3205f0022.jpg

My 15 did the same thing at about 15,000 miles tightened them all up and now they’ve loosened again at around 33,000

FYI, my truck is a 2017 Chevy Colorado.  Nevertheless, the noise I was hearing matches exactly what you all are experiencing.  
 
It appears as though my problem with the issue may finally be resolved. I attached service notes from the dealer. But in a nutshell: Near the B pillar pass through connector, there are two pieces of sheet metal sandwiched together that were causing the rattle. There should be a small amount of space between the two pieces, but there wasn't enough. Which is probably why I only heard the noise during warmer weather, as heat causes expansion. The techs at the body shop injected some 3M foam in the area of the B-pillar pass through to eliminate the two pieces contacting each other.

Anyone noticing this rattle to be temperature dependent?  The cooler it is, the less I hear it. 

I've noticed it on my 16. When its cold it does not make the noise but as soon as the cab warms up it does it.

Thank you for posting this. Its cold now so this annoying noise has slipped my mind. Come summer I will be removing the panels to see if I can locate what the technicians were talking about in the repair order.

So glad you posted this.  I was having this issue but since it has gotten colder lately the dealer could not reproduce the noise and had no idea what to do.   So instead of waiting until spring and hoping they could hear it then I sent them your print out and they did exactly the same thing.  Time will tell if it worked for sure or not, but at least they did something and didnt just tell me I was crazy :)    I also had the rattle in the dash going on and they took my entire center console and dash apart and found 2 bolts that were not tight.   So hopefully now all my random noises are done.

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.

I have this same B pillar rattle / metallic ticking noise in my 2017 Silverado 1500 Crew Cab.  The noise was real bad last summer when the temp warmed up. It was driving me absolutely bonkers. 

 

Because I just knew taking it to the dealer was going to be a real pain in the neck and they probably wouldn't be able to fix it, I took the top part of the interior B pillar trim off myself and decided to spray automotive /marine foam into the empty space inside the pillar .  It didn't do anything to stop the sound.

 

During the fall and winter it went away but mysteriously now here in January it started rearing its ugly head again over the last couple days, getting worse back to the point it was at last summer.

 

Zooming ahead to now, and reading that it could be the cut out where the wire harness goes to the door, do you guys know if this is something that maybe can be accessed and fixed by somehow popping open (or popping off) the rubber wiring harness you can see when the back door is opened?  I really don't think I want to mess with those trim panels inside out of fear I'll never get them back on flush again (or worse, breaking or cracking them)

 

Any thoughts  on this?  

 

Incidentally I've also been trying to figure out how to stop my passenger seat from rattling when its empty :(

The other thing I find interesting is the pass through connector is kind of low in the pillar, but the noise seems like its up in the area where the seat belt comes out of the pillar - right next to my ear.

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.

I think...think I figured this out...if you pull off the pillar cover (whichever of yours is ticking) mine happened to be the rear in a 15’ crew. At the bottom of the seat belt right before it goes into the reel there is a plastic guide that pivots and is very close to the body. I put a piece of door insulation (home) like a foam on adhesive behind it on the body so it cannot tap against the metal. Now I’m not positive because I just did this today and typically if I open or close that door I lose the tick for a while but I also think it is here and there due to the tension on the belt at times. Again not sure this is the fix but it is all I have found that gives me hope not to steer it off a bridge. Update...noise is back two days later ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
