    I suddenly got many warnings, Hybrid System Malfunction, Pre Collision Malfunction, ...
    The scanner showed a SRS ECU airbag failure. It was cleared but then came back up.
    Took it to the dealer, they replaced the part, car works fine.
    Seems crazy, why would SRS ECU failure cause about 6 unrelated alarms. Toyota rep said she never heard of this. Any explanation?
