My only hope is that if anyone manages to get their truck cabin completely sealed, they and their passengers are on a back road somewhere and simply run off into a field when they all pass out. The only smell I get in my truck is the duck dynasty air freshener swinging from my mirror. I drive in Houston all the time.

Gm called and said they may have a fix for us...They said when the vents close they still stay open about 10% (WOW). Anyway they said they can reprogram the onboard computer and change the level of cl

Well the results are in and I couldn't believe what I was being told....I have attached the write-up so you can read it for your self....You may not want to have a truck like this if you live in areas

My question is. can you acces the flap that is the problem through the glove box. If so you should be able to do a little mod to make sure it closes all the way. Or maby seal it shut.   Sent from m

Most of the time I have the radio crank pretty good so if the truck is rattling or making any noises I wouldn't notice. Now smells I would notice, there is nothing any different with this than any other ride Ive had. GM has made these trucks pretty quite so I can imagine hearing little sounds is to be expected. The roads we drive on aren't perfect, a lot to ask at the speeds we travel.

Did any of you get this corrected or any updates? Do any of you know if the recirc door is actually closed 100% or 90%? Does anybody know how to get to the recirculating door? And if the door was only 90% close, has any of you gotten the dealer to close it a 100%?

I have given up for the time being....check out my 8 March post. There is a document attached that gives us options. The dealerships should have been aware of this document or maybe communications between the Service Manager and the techs is not the best. I have stopped doing GM surveys because I don';t know how to answer them....

Just got my truck back and the whistle has stopped now.... they performed the TSB PIT5229... im not sure if its the same as PIT5229A. The one you posted says to disregard bulletin PIT5229 but that's the one the service guy told me they did.

Hmm, TSB PIT 5229. Sounds like an abbreviation for TSB MONEY PIT 5229.

No complaints here at all. Seems to work pretty well but i've only used it just a couple times. I don't seem to get the smells like I used to in my G8. Guess cause of the height is above most stinky exhausts.

Still looking for more posts on this, but I've had my new truck 3 days!!! Love everything thus far except that in recirculate all outside smell enters the vehicle. Skunk, cigarette smoke, exhaust, doesn't matter!!! No way to prevent it. I will look around for more solutions here, and take back to dealer Saturday, but if this isn't fixed I will absolutely cry fraud and seek full return and legal options immediately! No other vehicle I have ever been in in my life has been like this! The responses I've read so far are complete crap! How can 100's of car designs over years and years of design not have this issue, and suddenly a car manufacturer claims this? Give me and you a break. A Kia at1/4 the cost is showing better qualityat this point. Additionally, I've got resources others don't, so we'll see what happens.

 

I've owned Toyota for 30 years, preaching Detroit designs were garbage. I bought this truck bc it is so nice, but 1 day in I am regretting this purchase, and will let the world know!!!!

Just pulled this from the owners manual, so by definition and description, not performing as designed!!!

 

"Press Recirculation Mode to quickly cool the air inside the vehicle or prevent outside odors from entering the vehicle. It is not available while the Defog or Defrost Mode is selected"

 

Funny!

My 2015 GMC 2500HD Denali does this, also. My father's 2015 Silverado Z71 does this, also.

 

My previous 2008 Ford F-150 did NOT do this. My father's previous 2002 Silverado did NOT do this. My mother's old Chevy Impala did NOT do this.

 

This is ABSOLUTELY a design flaw on Chevy / GMC's part and they need to fix it. This is something that would make me never purchase a GM product again. I have had the fumes in the cab get so strong, while waiting in traffic, that i've felt light-headed at times. This is just completely unacceptable. Recirc should, as the Owner's Manual says, prevent outside odors from entering the vehicle. At the very least, GM should honor their own printed words.

 

GM needs to fix this immediately.

Have had my truck for a year and never really noticed this until the other day when I was stuck behind a diesel truck for miles on a curvy 2 way road. I hit the recir button but the fumes were still entering the truck. I was a bit surprised so thought i would look it up on here and sure enough it is DESIGNED that way LOL. Now these trucks apparently have a replaceable cabin filter is there an option to get a charcoal filter? I do not want to die or pass out from lack of oxygen so not really interested in sealing up the cabin like a casket just would be nice to cut down on the outside odors a bit.

Had my truck in again and no luck. They keep trying to push the deal that opens it up to 80%, as a possible remedy, but that ain't gonna fix it. I did learn that dodge had a similar issue a few years ago that was root caused to a warped door in the system. I've seen how the gmc works, if you look behind and through where the inside air filter goes , you can see the door and large hole it covers when in recirculate. The opening is about 5 inches wide by 3 inches. There is however no way to test the seal of the door without removing the entire dash!!! My thoughts were that if there was a way to put additional sealing on that trap door then when closed it should help. The odor seams to flow through the air way just above the hood where it meats the windshield on the passenger side.

 

I've also tried to look around the rest of the cabin and engine area to see if there are any other gaskets or areas where air can filtrate in, but simply can't see enough to make that determination.

 

I will say this, I love this truck but only after 3 months and seriously considering trading this in ONLY because of this issue. To another's point when in traffic it truly is difficult to breath.

 

I've also added clothes drying sheets around the cabin filter and that doesn't seem to help for more than a day! Also it seems to be worse if the system is set to only the feet. But the difference is nominal.

 

GM hear me!!!!! This sucks do something!!!!

I think they have charcoal type cabin filters for the older models so I assume there will be some charcoal filters available for 2014 and up, maybe they are available now? If someone runs across a source for a charcoal cabin filter I would appreciate a link......................

Has anyone received any relief from this problem?

 

We bought our 2014 Sierra in August 2014. We've been taking it in for service since about November 2014 for this and other issues...mainly this one though. I have a current open case with GM after the one in July was closed. The response each time is the vehicle is working as designed. Last couple of times, I'm referred to the owner's manual which says that the "Air is recirculated to quickly cool the inside of the vehicle. It can also be used to help REDUCE outside air and odors...". Well, the Quick Reference Guide from the same vehicle says, "Recirculation Mode to quickly cool the air inside the vehicle or PREVENT outside odors from entering the vehicle...".

 

I'm really tired of breathing in vehicle exhaust, every dead animal on the road or the person's cigarette smoke from the car next to me. GM has not been responsive and I'm feeling ignored while they are dismissing this. We feel this is a safety issue and they aren't taking it seriously.

 

Hoping someone has received a fix or resolution to this.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.

      2021 vs 2026 handling (1500 X31 Sierra)

      By dennismc · Posted

      I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it.

      frustrating P0446 code

      By Old Bay · Posted

      So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.

      loose lug nuts

      By newdude · Posted

      Any grease on the stud threads of any kind?   Wheel studs should have NOTHING on them for proper torquing and so the nuts don't back off.     Are all of the mating surfaces clean?  So wheel, rotor and hub?     We've had plenty of trucks at work with that wheel, this is a first to me.  Makes me think they've got a lube tech putting anti-seize on all the wheel studs or some kind of grease, and they need to stop doing that.  To have 11 other trucks with the same exact problem.

      2027 Chevrolet Silverado: Official Discussion

      By Flynlow · Posted

      I was a Chevy guy for years, then switched to GMC because I liked the looks better.  I'm actually thinking I like the Chevy looks better than GMC for the first time in a lot of years.   One thing I know for certain, the new GMC dash is hideous!  Chevy wins this one!
