Q: ABS malfunction.

asked by on

The ABS light goes on and off. The braking system will sometimes grab, even when the brake pedal is not pressed.

It is interesting that you found that your brakes system is "grabbing" without the pedal depressed. However, there are many things that can cause your ABS light to come on from a failed sensor to low brake fluid. I suggest you have a professional, such as one from YourMechanic, diagnose and repair your vehicle.
