Smell coming from vents.

[CierraGraves]

I’ve been using the tropical fiesta spray at home, and the enzyme formula really cuts through stubborn smells without that heavy chemical vibe. The mix of pineapple and peach is subtle enough that it doesn’t clash with other scents in the room. If you’re trying to freshen up a smaller space, the travel size was handy for me, especially for keeping my car from smelling like smoke after long drives.

I’ve seen some people on here talking about this. There’s an exhaust like smell coming thru the vents when I have my AC on now. I changed the Cabin air filter, which was due for me to change. The smell is a bit less but it’s there. Does this possibly have a connection to the Cracked fuel injector CSP? If anyone else experienced this did you get it fixed?

sounds like you have a cracked catalitic converter. I would take it to them tell them you smell exhaust in the car when it has been idleing and they will check it.

Anyone have any updates on this issue? I've been to the dealer three separate times for a similar burning oil/fuel smell coming through my vents without resolve. The smell gets very strong, and I have to open my windows and/or turn on my internal air recirc. The dealer first stated they couldn't locate/replicate the smell. They said coolant was leaking and went ahead and replaced the water pump and other coolant system items per a TSB. Smell was still there. The second time at the dealer, the service representative came out and smelled it immediately. However, the technicians stated they couldn't locate or replicate the smell after a "thorough" inspection. They said the foreman also drove the vehicle and couldn't smell it. They went ahead and replaced the cabin and fuel filters, and completed an oil change in case this would help with the issue. Smell was still there. The next time the foreman drove in the car with me and smelled the burning smell coming through immediately. He pointed out a small damp spot near a gasket when we popped the hood. They now claimed coolant and oil were leaking (how did they not catch this the previous two times in the shop for a week at a time). They used a dye test to pinpoint the oil leak in the back side of the timing cover. The coolant was leaking from a faulty coolant hose tee fitting. After addressing these leaks, the smell was originally lessened, but has now come back even stronger. I first thought it was old residual oil burning off, but it has been over a month.

Update: I went to a separate dealer and told them to check the catalytic converter. This was the issue! Thank you guys. They fixed it, and it was associated with a recall and/or covered by warranty, so no out of pocket. Not sure what the first dealer was doing. It is running much more smoothly as well.

It will probably crack again after 40-50k miles. I’m on my third one
