I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.
The traction control works in tandom with the ABS system. You have two ABS sensors...one on the front right wheel and one on the front left. You'll have to take the wheels off to get to them. Once the wheels are off, look in the back side of the wheel bearings and you will see a ring with teeth like protrusions... kinda like "little Gears". If you are not sure where to look just follow the CV axles from the transaxle to the spindles. They are located on the ends of the cv axles. If you notice and debris or grease on the gears then clean it off with some brakes clean. Also check the wires leading to the wheel speed sensors (aka abs sensors). be sure they are intact. The rings may be built into the wheel bearings themselves and if that is the case, you will have to replace the wheel bearings. There could also be a problem with the body control module. It would help alot to get it scanned if you feel you may have to replace something. No sense in shooting in the dark try to replace parts that don't need replacing. Hope this helps.
