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

Well i just have a whitle sound coming from my air vents when my truck is recirculating mode so im trying to see if anyone has or had this issue before?

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.

      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.
