    Hello guys,
    My Prius 2010 has been sending some weird light warning:
    - Bake system warning light (yellow and red)
    - ABS (antilock brake system warning light)
    - Antiskid (stability control)


    It all appears at the same time and while on, I can still drive the car but the brake is not usual, like stiff.
    They were gone after i changed 12v battery but came back on after 3 days

    welcome!
    when you get trouble lights, they are telling you there is a problem. to find the problem, you have to read the trouble codes by hooking up a scanner to the obd port under the dash. dealers and hybrid mechs have them, or if you want to diy, there are several good ones available and you can find threads on them here.

    Like @bisco said, you will need to read the codes with a Prius compatible code reader. There are several possible causes, some of which are cheap and simple and some of which are expensive. Guessing gets VERY expensive.

    Then you must have used one that doesn't talk to all the computers in a Prius. If there are warning lights, there are codes because it's the codes that turn on those lights.
