Ever since I bought my car last year I have had some problems with it smelling, but now its getting really bad. Before it only smelled after I would get on it, and whoever was behind me would smell it. Now pretty much every time I stop driving, the inside of my car smells like it. As soon as you get out of the car you no longer smell it. It does not smell by the exhaust tip or anything like that...so I have no clue what it is.

If it helps anybody it smells like rotten eggs

Hello Ceej,

I checked out Oil Filter Guide - Oil Life Monitoring - Dirty Oil Filter | ACDelco (they have a troubleshooting section) and it looks like that smell is a possible emissions problem. As your vehicle is a 2010, you should be well within any emission component warranties, though I can always get you specifics if you wanted to send me the last 8 of your VIN.

Best,

It's your cat

 

I've heard that the cats are recalled? So I'm assuming they will just fix it for free

 

Cats were recalled on the ss/sc. Govt. Mandated 100,000 mile cat replacement on all so take it in its free
