Crazy warning lights.

What could be wrong? Not the brakes. Seen that before.

  1. OBDC?

  2. Drive Train?

    Do you have access to a OBD reader? Even some cheap one works well.
    Be nice to know what codes it's showing.

    Yeah, Toyota is known for lighting up the dash with all lights to grab your attention. It could be anything, but as recommended above, plug a scanner into it or take it to a mechanic that has one. They'll be able to tell you if it's air sensor, wheel sensor, etc...

    Mine did the same thing a few months back.
    Ended up costing me around $1.2K I think.
    Left side cat converter went out at around 80K.

    P401 or similar code for catalytic/02 sensor failure, iirc.
