I have a 2005 Santa Fe 2.7 that has ABS and Traction Control. A problem has developed and not sure where to look for a fix. At random times the ABS seems to actuate itself for no apparent reason. It happens pulling into parking spaces, turning the wheel sharp in general at low speeds. I have even had it happen at low speed while on the gas. At various times the ABS and TCS lights come on and stay on for periods of time. I have checked the brakes themselves, but I feel the problem is in the ABS/TCS system. No obvious things wrong with the speed sensors themselves. Any ideas on what this could be??? Any help would be greatly appreciated.
