my 2002 grand ams abs,trac off,and check engine lights come on when the gas
level gets to quarter tank why is that?

Does this happen everytime, or just on a couple of occasions that
coincidentally occurred when the gas tank was at 1/4?

I have this happen 1-2 times a month in the winter time on my 2001, wheel
sensors acting up I presume, sand and salt probably have something to do
with it. If I turn of the car and restart it, it usually clears up, and yes
the system works fine then.

Otherwise, probably an electrical issue in the dash..
