I own a 99 Pontiac Grand Am SE. When I pull out the low trac light will sometimes, not always, come on. Then when I am driving down the road the ABS and the trac off lights come on at the same time then stay on. However there are times when neither the ABS or the trac off light come on at all. It seems to happen most often when I hit a bump in the road or something. What could be wrong?

It sounds like a wheel speed sensor may be failing on your 1999 Pontiac Grand Am. Fault codes should be sorted in the ABS control module which will help isolate the cause of your problem. Any stored codes should be diagnosed and repaired as necessary.

Have a mechanic check your wheel bearings.
