The ABS light comes on and then goes off from time to time. Is this something that needs immediate attention?
ABS Light comes on occasionally on 2001 Isuzu Rodeo
When the ABS light is on you will not have the safety of a vehicle with anti lock brakes, but you will have the normal operation of the braking system. This becomes an issue when the road conditions are slippery or you have to make a panic stop.
Did you get new rotors installed just before this happened? If so, have them checked and make sure the sensors don't have any metal shavings on them from a brake job.
