They had the truck for a week and couldnt get it to duplicate the smell. I havent driven it much since i got it back but im sure it will still happen.

The smell is on the outside coming in. It was first noticed when i was towing my weekend warrior so wasnt floring it but it was under a load. Now it just doesbit all the time.

It smells of propane. Truck isnt overheating or running any different.

Hello. I have a 2014 5.3 4x4 30k miles and have a smell of propane off and on when driving. It does it everytime I drive and you get whiffs of the smell. Of course the dealer cant get it to smell and my warranty is out in 2 weeks. Any ideas would be great. Thank you
