Ok, I wandered through these hallowed halls of wisdom looking for a little nugget of knowledge. Since I haven’t found it yet, it’s time to reach out and … I have an '05 Suburban. I love the boat but recently have noticed exhaust fumes in the cabin. My first trip to the dealer was a warranty deal where they replace lifters. And, they said they couldn’t detect any fumes. I picked it up and the fumes were still there … stingy eyes … and my wife wouldn’t get in the car. Ok, so some of you might see that as an advantage, but she has the credit card. I took it back the the dealer and they swore they couldn’t smell anything except the dog … who, by the way, doesn’t ride in MY car!!! and … nevermind … On this second trip they said there was a loose smark plug. But they stil couldn’t detect any smell.mThey even said they had someone sit in the car for a half hour with it running and they didn’t detect anything. Even when they woke him back up and revived him (kidding)… I have to admint it is better. I aired the Burban out … cleaned it out … but when I am idling in the drive or at a light, the smell starts creeping back in. They say they checked everything including door and tail light gaskets, exhaust, and no luck. I’m old but not dead. Have re-built a few engines in my day … but not for a few (many) … (lots of) years. I think I know the old familiar smell of fumes and can tell from gas or antifreeze … but just am not good at crawling around under the chassis anymore. What do you think? The dealer has been reliable for years, but I just think there’s something going on here. Should I try another dealer, find someone to test the cabin air quality, or update the old life insurance? ---

Unless it is for warranty service or recall work there is no need to take a vehicle to a dealer. You can have any mechanic look at things - especially the exhaust system. That is what I suggest you do. Find a local, independent (i.e. non-corporate chain) shop. If it specializes in exhaust/muffler work all the better. Have them provide a second opinion. ---

Get thee to an exhaust shop. An exhaust specialty shop has the sniffers and smoke tests etc to find even just a crack. Good thing the odor is warning you because the CO is odorless and will get to you on an extended trip if not handled asap. ---

I suspected as much. Now I’ll be in search of a shop with the right stuff and snuff to check this out.
