NHTSA Complaint #11595614 — 2005 TOYOTA RAV4

Very often, while driving at normal speeds around curving and hilly roads, the traction control light comes on. It even locks the speed until the light goes off. And sometimes the VSC (Vehicle stability control) light comes on and takes control of the car. When the warning lights go off, the car returns to normal. I took the car to Kauai Toyota Service Department. They said that they cannot troubleshoot the problem until one of the lights stay on continuously. It is a little disconcerting when this happens while driving. I love this car and what to keep it. But I want to get to the problem and fix it. Is it possible for a repair facility to use a computer to back track the alarms and pinpoint the problem? Thanks for your time and response.
