I took my Avalanche and a new Travel Trailer on a shakedown cruise of about 1000 miles from Loveland, CO to Santa Fe, NM. ?One third of the way thru the trip my wife and I started getting this pungent odor in the passenger compartment whenever we stopped with a window open. ?We thought we had a propane leak from the trailer but we checked it out and it wasn't the trailer, as demonstrated by the fact that without the trailer we got the same smell.
Since my wife was getting nauseous from the smell, we took the Av into a Chevy dealer in Santa Fe to check it out. ?The service people smelled it as soon as I pulled in. ?They pressurized the fuel system and couldn't find any leaks. ?The Service Manager checked out Chevrolet's web site and found nothing. ?He called the factory and they didn't come up with anything.
The Service Manager, who was very sharp, then remembered a similar problem with the Tahoe. ?He said they had to change out the rear differential oil and replace it with a different type..he mentioned "grape". ?He decided to try that on my Avalanche. ?When they drained the differential oil I took a whiff..sure enough, that was the smell. ?He changed the oil, but told me that I should also take it to a dealer when I get home to get an extended vent tube put in as he didn't have the part. ?
Despite his good effort, the problem didn't go away by changing the oil. ?We now have this odor all the time and my garage reeks of it. ?I'm scheduled to see my dealer on Monday morning.
Now I'm really skeptical that this vent tube will fix it. ?It may deflect the odor in a different direction which might keep it out of the passenger compartment, but it's still going to vent to air and stink up my garage. ?In fact, everytime I stop somewhere you can smell it. ?It's particularly strong inside the driver's side rear storage compartment. ?(That's why a fuel leak was suspected.)
Since no one seems to have reported this problem before I'm afraid I could be in for a rough time in getting to the root of this. ?By the way, I have just over 3000 miles on the Av, it's a 2500/8100. ?My engine oil was changed out before I left for the trip.
If anyone has any good ideas I'd welcome them. ?I'll keep you posted on my adventure with the dealer on Monday.
