I purchased my car 12/13/14 and was loving my car until after my last fill up.. I DID NOT TOP OFF !!!
My car smells from gas. on the outside and from the a/c vents. My wife wont ride in the car. I took it in for service and they spent over an hr running the computer to see if any emissions issues or vacuum issues etc.
NOTHING. lifted car up and noticed no leaks. Mechanic did smell gas at first when i pulled in. Then they came out and told me they found the issue.
( i didnt beleive what they told me but this is it) a vapor value under the car has spider webs and kept the
valve slightly open and they cleaned it out and that was the issue...
Now 2 days later and after a new full tank of HESS preminium gas. i have the gas smell back.
Anyone with a suggestion.

Good luck with that, definitely DO NOT DRIVE IT. Best to be safe than sorry. I remember last year a family was out test driving a 2015 Yukon when the thing went up in flames.

hannity, it's kinda weird you posted that fire when it has nothing to do with his problem. That was a loose transmission hose that caused transmission oil to catch fire. There was a recall very early on for that. I do agree with the DO NOT DRIVE IT, hence they said it was going to be towed.

someone suggested it might be a sensor. but wouldnt that show up in the computer diagnostics.
also i notice morning starts are sluggish ( temps in teens for last few weeks) and the truck shifts a bit rough at times into 2 to 3 gear!!

just got back from the dealer after getting it towed. When the tow truck picked up the car we noticed a small leak in the underside of the car about 12 inches back from the wheel base in the center of the car. Looks like a fuel leak (hose). Hopefully its that simple..

First try a different fuel brand. Just to test it out. If the gas smell is still present, take the car back in to the dealer. Take it back as many times as you have to and get everything documented. I have seen GM replace the entire gas tanks to remedy this type of problem.

I've also been dealing with this frustrating problem that happened a few weeks ago. I smell a strong gas (almost propane like smell) coming from the AC vents. Also you can smell it coming from under the hood. It's very overpowering at times where I have to roll down the window. I took it in to North County Cadillac (Escondido, CA) and even though my service advisor could smell the strong smell, they said they couldn't isolate the problem. They are pretty bad there.

I just dropped off the car to Hoehn Cadillac (Carlsbad, CA) and the service advisor could smell the strong gas smell not only in the car but also under the hood. I'm really hoping they can isolate the problem this time.

hopefully you read my issue that i posted. it ended up being an o ring on the injector.

i ended up being the one that figured the issue out. i placed the car on a upward incline and noticed fuel dripping out of the front end. while the car is on a flat surface it didnt drip..

I told the dealership that but they said it wasn't that. They just called me and said they have isolated the gas smell to the front driver's side wheel well. Strange as there isn't anything with gas there. They said they need to investigate it further tomorrow. Hopefully they can solve it. He said they have never seen anything like this before.

That doesn't sound like a likely spot. Ask if they took the manifold cover off and checked the injector o rings. Or are assuming it not that. My service center thought they found the issue at first.... lol a spider Web in a vacuum hose. I laughEd at that and said I'll see them in a few days. That's when I called to get towed in and figured it out on my own. My gas smell was terrible and I figured unsafe to drive.

I suggest having caddy tow the car in each time. For safety reasons. And expense..... they will try harder to fix it.

The service advisor called me today and said they are having a difficult time isolating the source of the odor but that it appears to be emanating from the left wheel well. That still puzzles me greatly since how would gas come from that area? He said the technicians are "going to try to neutralize the odor but if that doesn't work they need to replace the wheel well".

Seems strange to me that the odor would be coming from there as I've had NO work done at all on the vehicle and it only has 5,500 miles. He said they are speculating that there is a foreign matter that produces the odor when it warms up". That doesn't seem likely to me because sometimes the odor comes on immediately when you turn on the car. It comes in through the AC vents. But he said that the vents are blowing the gas smell in from that area.

How frustrating.

Finally a glimmer of hope. They finally found the problem. They said that the odor is coming from the vent of the front differential. They said that the smell is coming from the gear oil (which smells like propane). Now they are going to figure out how to fix it. Hopefully it can be resolved soon.

No way a vent valve for gear lube will give off that much of a smell. All those differentials are normally vented to the atmosphere. Only when you open up the pig will you smell the gear lube. And it definitely smells a lot different than fuel.
