    I have a 2008 prius with about 122,000 miles.

    All my warning lights on the dash board are on: ABS, VSC, checjk engine, tire pressure sensors, BRAKE, exclamation point inside circle.

    Also, gas mileage has dropped from 51 mph to 43 mph.

    Also, sometimes when starting the prius i get a constant high pitched beep for around 5 or 6 seconds.

    Is my traction battery dying?

    welcome!
    not necessarily. best to read the codes and post back here for help. the high pitched beep may be indicating a brake issue.

    The codes are P1121 and P1116. These have to do with the coolant control valve and coolant temperature sensor.

    Welcome to Prius Chat David. Sorry I can't help you out with the codes, but someone will pitch in before long with advice.

    Codes have helped point you in the right direction.
    Now you just need to fix those issues.
