    Out of nowhere a constant high pitched double beep sound started and we cannot figure out why. It keeps beeping even when it’s turned off and even when my husband disconnected the 12 v battery. No lights came on. What can we do???

    Nevermind. It was the EZ pass. Tok a ridiculous amount of time to figure out.

    Wait. The EZPass itself beeping, or was it sending conflicting signal frequency and making the Prius confused?
