I have a 2005 impala that has periodically displayed the service traction device message, usually along with the ABS light. I have let this go over time, as I never noticed anything that might be a problem while driving the car. Recently though, when the car shifts, there seems to be something that I would describing as slipping. This doesn't happen all the time, only sometimes. Any suggestions?
Don't mess with the ABS light get it diagnosed and fixed. Your brakes will work with the ABS light on but you will skid because the system will switch to basic hydraulic action with no control of how much to each wheel. If ABS is on then it is not working.

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 PROBLEM IS WITH A HUB WHEEL SPEED SENSOR OR MORE LIKELY THE HARNESS LEADING TO THE HUB.
CHECK THE RESISTANCE AT THE HUB CONNECTION, IT SHOULD BE BETWEEN 900OHMS AND 1300OHMS. THEN SWITCH TO A-C VOLTAGE, IT SHOULD BE 100MV WHEN TURNING THE WHEEL BY HAND. IF BOTH CHECK OUT THE PROBLEM IS IN THE WIRING TO THE HUB.
THE RIGHT FRONT HUB USUALLY HAS A BEND, DOWNWARD THEN UPWARD NEAR THE CONNECTOR TO THE HUB. THAT IS WHERE THE PROBLEM USUALLY OCCURS.
NEW HARNESS WIRES CAN BE BOUGHT AT THE DEALER.

You'll need to have the codes read from the computer. You will have a code that indicates one of the front wheel sensors is bad. This could be the case, but they are very expensive as they are built into the wheel bearing assemblies. It is more likely that the wiring harness between the frame and the part of the front spindle that holds the harness, has broken internally. It is a very common problem and can be repaired with a new wiring harness section or by tracking down the fault and repairing it.

The ABS control Module is going bad, that all, since the ABS and traction work together you will get both lights on. Take to a mechanic, expect to spend about $500.
