I've had my STS-V since August 2012. I just began to get used to it and started seeing what it can do.
I noticed that after WOT runs the engine , not the exhaust, smells like its on fire. What can this be? Anyone have a simliar issue?
it's not the brakes, as it happens even after on-ramp acceleration to the hiway. I'm convinced it's the cats. I took it to the dealer but they were basically unwilling to do anything, citing a TSB that says it can be caused by bad gas. But for me it happens all the time, and I fill up at several different gas stations.
FamofV, I do suggest bringing your concerns to your dealer's attention and having their technicians run the proper diagnostic checks on your STS-V. I'm happy to contact your dealer anytime you would like to involve them, and I'm also here to check for any possible recalls, etc. that may be open on your vehicle. If you would like me to look into the matter further, please send me an email at Katie_Lucille@gmexept.com that includes the last eight of your VIN.
i had mine fixed at 70k, but it was a total tear down of engine. i was informed from my mechanic that the pressure in the crank case can force a small amount of oil out of the rear main seal also. i would invest 30 in a vent to see if that helps before the next step.
