Hi there. It sounds like you may be experiencing ABS actuator electrical faults. The actuator is an assembly that contains the ABS pump, solenoids, valves, and controlling computer. Is the Hybrid warning indicator coming on? This could be an indication of a Hybrid system error that will need attention by a qualified hybrid technician. I suggest having a qualified hybrid technician perform an inspection to avoid replacing unnecessary parts and safety concern. Your Mechanic has hybrid technicians that can assist you with an ABS light is on inspection.
