Our 2010 Toyota Sienna recently had a cel go on. No codes were found by local repair shop so took the car to Toyota dealer. Dealer gave us error code u0123, u0124, u0126 and said we would have to replace the abs actuator pump which will cost $3600+. I searched online and many have/had the same problem. Also read that Toyota has already covered a extension warranty for the camry hybrid with the same problem part. One of the code was for the yaw rate sensor which was also part of a recall on some Toyota and Lexus cars.
