One problem related to automatic transmission control module has been reported for the 2011 Toyota Prius. The most recently reported issues are listed below.
Car stalled pulling into traffic. Took about 15 sec to restart. No diagnostic lights lit up on dash. Car lost power last month and engine light went on and engine could not be restarted. Had to be towed to dealership. It replaced valve assembly for vacuum and reprogrammed pcm. However, that issue was preceded by a creep of diagnostic lights (course of 1 hour), from check oil to check engine, and then it completely shut down.
