    I have had the same problem three or four times. The first few times it was covered under my extended warranty so I paid nothing. It was a problem with the right wheel speed sensor or left, it alternated each time. Since my warranty ran out, it has happened again, but I don't want to pay the $300+ to fix it. So I've been driving with the light on for about 6 months. I really only notice any braking issues in wet weather or if stopping on bumpy pavement.

Trac off simply means that your traction control system is turned off. This light generally comes on when your car is started for a while like many of the lights just to ensure everything is working. It does sound like you have some kind of problem developing but it's very unlikely that it has anything to do with the traction control system. Generally in mid-priced cars like the alero all traction control does is either stop power to the wheel slipping or apply gentle brake pressure to the tire that's slipping. Just get a diagnostic run would be my suggestion. You can turn the traction control off yourself if you want to understand it better, many car enthusiasts do so as it allows you to use sliding and traction loss to your advantage. Leaving traction control on does generally increase safety for your average driver, but makes it virtually impossible for an experienced driver to perform any of the stunts we often see in racing.

5.9 Lt 2001 dodge durango has 20 percent compression on cylinder 7, ran really luggish and engine shakes alot, was told could drive on 7 out of 8 cylinders after a couple weeks of driving it, i started it...

it sounds to me that #7 has a valve train problem, wiped cam to broken rocker arm,bent pushrod,broken spring,bent valve or burnt bad! Or it has broken ring on piston. shouldnt have kept driving,very bad idea. pull valve cover to check valve train. I would start there before going deeper into motor.

Trac light came on

Your transmission probably has some severe problems. If a sensor in the tranny has gone bad and is keeping it in first gear, it won't be able to do anything, not even crank.

Enhanced Traction System Warning Light (TRAC OFF)

Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.
