Got the same issue today. This time in expert mode. Was driving easy so managed to read the fault in dash - it said collision detection error - visit your dealer. Most likely I will

Maybe this is needed. Could the yaw sensor be that sensitive that as car rotates better it confuses the collision detection? This would be strange as grip levels can vary and thus setting sensor to too tight tolerance would certainly cause potential issues..

There is a new Service Bulletin out for Yaris Radar recalibration, now the caveat of the matter is :Will this make it even more sensitive or less?

I havent received a letter yet, but im ignoring it as my car doesnt constantly send me warnings, that being said, if you take your time to research the Systems weaknesses, you will ultimately drive in such a way as not to trigger the system (like when in residential areas with cars parked on both sides)
