Hi - I've been following threads like these for several weeks now but of course I think *my* problem is unique. '09 Prius Touring edition, 31K miles but just past the 36 month warranty period... 3 times in the last few weeks while driving (each time has been a hot afternoon), the big red triangle, the ((!)) [braking?], VSC and generic "Check Engine" lights all come on, as well as the car icon w/ exclamation point on the center screen. I may be crazy, but there doesn't seem to be any change in the car's driveability. After 1 ignition cycle the brake and VSC lights go out, and by 3 or 4 cycles, the other lights go away. But a day or two later (3 times in about 6 days' driving) the whole procedure repeats itself. I HAVE had the 12v battery replaced - last fall. The car was just in to the dealer for 30k service in June. I can't sense any change in braking or performance, but I've so far not had the time to call the dealer to schedule an appointment. I'm going to do that next week, but does anyone think I should park the car until that time? I kind of need transportation.... Thanks.
