    I have started to notice one beep when I turn off the car. This doesn't happen all the time, but it appears to be happening more often. There are no unusual displays and the car runs fine. Has anyone else noticed this?

    Do you, by any chance, have your cellphone plugged in, in the car?

    Mine beeps when the power is cut - which happens when the car is turned off.

    Just a thought...

    Yes, a weak fob battery has this symptom.

    Thanks for all the input. I don't have a cellphone plugged in and no sun roof. I will check out the fob battery.
