Smells From The Exhaust

[Bigdog9586]

When stopping for a red light and the windows down I get that stinky smell from the exhaust that used to be present back when snog junk was first put on cars. I haven't seen it in years until now. Anyone else with this problem and has the dealer solved it?

What kind of smell? A sulpher smell (rotten eggs) usually means a bad catalyst. Have the dealer check it out. A bad catalytic converter on a new(er) truck should be able to be replaced under the required federal emissions control warranty.

Bad converters (and the associated sulpher smell) were common when they were first being put on cars. It doesn't happen much anymore, but you still smell a bad one every once and a while.

Or is it some other smell?

I had the same type of rotten egg/natural gas type smell about 150 miles from home while towing a trailer (3000lbs max) to Sturgis two weeks ago. I thought it was outside, however it never went away.

Right now it's at the Dealer - the rear end is cooked - the smell was the 'fried' gear lube - It's all covered under warranty however they have me driving a base Cavalier for the rest of the week

Anyone out there know of any rear end/differential problems in these things

I'm just bringing this to the head of the list again to see if anyone has been experiencing problems like this

Just bringing this back up to the top... Was wondering what the outcome of this problem was. Mine has developed the same rotten egg exhaust smell and was curious what the dealer had to do to fix it I'm guessing they replaced the catalytic converter(s)... Oh well, first trip to dealership
Thanks!

I had that smell on my Dodge Ram. It was the Cat Converter. Sorry to hear your having problems. Most dealerships (Chevy) are good to thier customers. I said Most....not all.

PS. Lets refrain from using terms like rotten eggs so close to dinner time.

Have been smelling something for a few weeks now, but couldn't determine the exact smell. I think you have covered it now though. Will be going to the dealer ASAP.

Just a secondory question: How many of you go back to the same dealership where you bought your AV? I bought mine 250 miles away from where I live, so I will have to be taking it to our local dealer. Because they did not sell it, I am wondering how interested they will be in fixing any problems.

Just wonderin . . . . .

hi, just wanted to make a suggestion. if you are going to wind up having the cat. replaced you might want to look into a hi-flow cat., especially if thinking about putting ona performance exhaust. just check local emission laws first, i can't put one on out here in California (or so I've been told) . the hi-flow cat will allow your engine to breath even better, maximizing your exhaust, plus maybe even a little louder

berto,
a high flow cat would be nice but I've only got 500 miles on the truck so I think I'll stick with a 'free' stock one for now Now if I was out of warranty, well....that's another story! I have thought about adding the Corsa exhaust system though, just need to fix this first!

Actually, you may find that the dealer will welcome you with open arms. True, they make some money off of you when you buy the truck, and your local dealer will be dissapointed you didn't buy it there.

However, over the lifetime of a vehicle, they make a lot more money servicing vehicles than they do selling them. Even for warranty repairs, GM reimburses the dealer for the costs, the "free" service doesn't come out of the dealer's pocket. If they think things through, they will realize that you are a source of income and they need to keep you as a happy customer. Unfortunately, not all dealers think that way.

Yes, dealers are in the busness to sell cars, but they're really in the business of selling service and parts! They just have to sell the cars so people will have them to bring in for service.
