I never get any smell while driviing but it has been real cold (relatively speaking to those of you in the North) here lately so I decided to try the remote start function on the keyfob.   After I let it run in the driveway for a few minutes and went and got into the truck, it smelled - and I don't mean just a little bit - it was strong.  I had to open the windows to let it out.  It was not a one time occurence.  It has done it every time I tried the remote start - about 5 times.  Is this happening to others?  FWIW, my truck has 2000 miles on it and I have had it about 3 weeks.

When I start my 2008 with remote start, the HVAC doesn't work the the same way it does when the key is on.

 

That may or may not have anything to do with your issue, except that turning on "recycle" for the HVAC may keep the system from pulling exhaust or other vapors into the cab during the remote start warm up cycle. The "recycle" may not be on with the remote start though, and then may turn to "recycle" when you are in the normal mode (not in remote start mode).

This isn't normal. 

 

Since the lm2 was introduced there have been several locations identified as potential exhaust leak locations. 

 

Get 'em to fix it.

I have worked on older diesels that had fuel leaks under the hood. The owner complained about diesel smell when the truck was stopped at stop lights. The fuel leaks were small, and dripped onto the top of the hot motor, and evaporated. Then the fumes get sucked into the cabin. When driving, the fumes would get blown away by the wind. I would start by putting the HVAC on recycle, and see if the problem is only present when the vehicle is stopped.

 

One thing you could try would be to drive the truck so that its thoroughly warmed up, and open the hood and see if the smell is present. Ideally without any electric fans being on.

I have a 2022 with 3300 miles on it and do not experience this to that degree.  I can smell a little bit, but not overwhelming and I remote start mine all the time.  I also have a 2015 2500HD that is fully deleted and has been for years.  There is significantly more odor inside the cab, but not enough that makes it obnoxious.  If you are experiencing that much odor, especially with DEF, I would have the dealer check it out.  It doesn't sound normal to me either.

I experience it too when starting up and letting the truck warm up.. the truck ventilation seems hosed up.. anything other than the dash air vents, defrost or foot lets nasty smells in, either outside or while idling... not terribly happy with this.  Occasionally I see a little pool of what looks like oily fuel on the ground where the truck was and wonder if that has anything to do with it.

Then it is in need of repair.

So I have the same issue and it’s terrible. Can’t even get in my truck after I started it for 10 minutes with the remote start. It also smells if I stop at a stoplight. I’ve been to the dealership three times with it no answers at all. I took it upon myself to look up online YouTube and what not. And I’m finding very similar problems. Everybody said it was an exhaust leak. I had my exhaust smoke tested, and there was no leaks. There is a small oil leak coming out the front of the crank on this motor, don’t know if that could be the problem. I went so far as to put a carbon monoxide detector in the truck and it will not set it off so that tells me it’s probably not exhaust so I changed my cabin air filter, and it helped drastically but this should not be a problem at all with a brand new truck. I am still checking in with GM to find out they  are aware of the problem. They just don’t have a fix for it.

      GM Hard Folding Tonneau by REV review

      By parthery · Posted

      Some clarification may help with some of these issues.   - Rev Industries is/was the division of BAK (now Realtruck) that makes covers under the OEM names.  So if you see one with a Ford logo on it, or if you are buying the GM Accessories cover, you are essentially buying a BAK G2 cover with different branding.   - Rev Industries now markets under RealTruck "Advantage."   - As of May 1, 2025, the Advantage covers now have a 5 year warranty.  Anything before that was a 36/36K warranty.   - Parts for the covers are available from Realtruck or BAK.  The email address to reach them is [email protected] or you can call them at 818-365-9000   - If the entire cover has to be replaced, you have to go through your local GM dealer.  Service dept opens an RO, notes the damage and submits it as a warranty claim.  Keep your paperwork handy so they can confirm when you purchased it and it's within the warranty timeframe.  Once the warranty claim is approved, Parts orders the replacement cover.  When it arrives at the dealership, service will remove and install the new one for free as labor is included under warranty.   - The Advantage covers are not the latest and greatest Gen 3 covers.  They still use the old school clamps, elevator bolts, etc...If you want the newer technology, consider buying your cover in the aftermarket world.  That way, if you have an issue you can deal directly with the manufacturer.   - Finally, RealTruck has a program with many of their authorized dealers that doubles the warranty to 10 years if the authorized dealer does the install.     Hope this helps.

      Welcome to the group!  My '22 just crossed 150K miles.  Runs perfectly.  Oil pump belt will be done in the next 30 days or so and onward hopefully for another 150K.  Love the truck.

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!
