Car had been parked in garage for 2 days. Drove vehicle about 1/4 mile and stopped for stop light. When entering intersection, heard a loud clunk. Car was very sluggish and noticed smoke through rear window. Stopped and found brakes locked and ABS/vsc indicators on dash lit. Had car towed to Toyota dealer who found "master cylinder seized code C1246 pressure sensor malfunction". they replaced master brake cylinder. Told them I wanted part back but they said Toyota had priority over part and kept it. Vehicle had 65,614 miles on it at time of incident. Also, brake system flush had been performed by Toyota dealer 4000 miles and 4 months previous.

Driving car in parking lot at 10 mph and suddenly would not move any more when in gear while engine running normally. Following indicator lights were on: "vsc on", "vsc off", and "ABS". wheels were totally locked and would not turn and tires drug when vehicle pulled up flatbed tow truck with winch. Dealer diagnosed as "found brakes are locked on. Found master cylinder not releasing. Brake fluid in booster". described to me by dealer on phone that pin in master cylinder froze for some unknown reason. Took almost 2 weeks for dealer to get part as national backorder (which could indicate a serious, frequent problem with this part). This could have killed me and my family if operating at highway speeds when pin locked. This appears to be identical to previous condition noted in ODI claim 10215967 on same year and model of vehicle. This is an extremely dangerous condition, should not normally occur, but appears to be happening to more than one owner.
