    I have had 2009 Prius Hybrid for about 1 year. Total miles 120K.

    Last 3 days, I've had these these lights (see image)
    Car seems to drive fine.

    - Big red triangle
    - VCS
    - Brake (yellow)
    - "CHECK"

    At AutoZone the scanner found no codes; no problems ?!

    Appointment at repair shop tomorrow. Shop wants to do tests, which can add up quickly.

    My concern is not getting overcharged, especially for "tests"
    And if it is big battery, what kind of questions should I be asking? Check modules?

    Thanks for any thoughts.

    The only thing those lights tell you is that there are diagnostic trouble codes (DTCs) that need to be read. Until you do that you're flying blind.

    The most important thing you can do is ask that your shop read the codes, document them, and give you a copy of them.

    Armed with those codes, more advice can be given.

    make sure you go to a shop with prius aware scanner, otherwise, they might be flying blind.
    shouldn't cost much for a scan, don't let them do anything costly until you look up the code meanings
