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.

    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
    • This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.  
    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
