    While driving, my car dash started flashing multiple malfunction warnings. Low brake power,ABS,BSM,PKSB, LTA, precollision and drive contol malfunction. Alert to pull over and call dealer. I pulled over, turned it off for a minute, then back on with same messages flashing. Towed to dealer. Dealer calls and say nothing wrong with it, battery perfect. X050E, X0512, X0531 .. all were history codes stating abnormal shifting. Was told, I must have not shifted right, and the computer got confused. What!? So I go pick my car up. Drive off the lot and all the warnings come back on, literally turned right back into parking lot and back to service line. Any ideas? 2021prime 30kmiles. Recent lift. Extremely hot weather down here.

    hard to say without codes. maybe check the 12 volt battery health. you really can't shift improperly.

    you might have to try another dealer

    Likely an electrical intermittent, but where? Could be something silly like a loose battery clamp or a loose fuse, but it could be almost anywhere.

    These posting by OP say all that needs to be said about the complexity of these cars, and the incompetence of dealer service personnel. In a sane world Toyota should reimburse all costs as well as lost time.
