The engine started cold and revved to 2500 RPM and then oscillated between 2500 and about 3000 RPM and never slowed down. I put the car in drive and drove it the block and a half to my house using the brake to stop at the only stop sign on the route but stopping was difficult. The next morning I experienced the same ultra-fast idle and drove the car on an errand that was about 2 miles distant. The same pattern persisted but the brakes were heating up and smelling from frequent use in keeping the car within the city speed limit. It also stressed the automatic transmission while braking against the fast motor. I started shifting from drive to neutral and coasting to control the speed while the engine speed oscillation continued. I parked the car back home and had a tow truck take it to marietta Toyota where the diagnosis was to replace the idle control motor at a cost of $669 less a $99 negotiated discount. That service solved the problem but the problem had the potential to overheat the brakes, cause one to coast in neutral without ideal control of the car in an emergency, etc.

There have been repeated disc brake mechanism (corrosion) failures where brake drags and wears or have "locked up" and dragged enough to effect steering. Has been serviced by both local Toyota dealer and independent service shop. Note: Lot better results and and less expensive service from local shop. Similar concerns have been widely reported on internet, e.g., car value / problem websites and reports.
