Intermittently, when my foot is on the brake and the car is stopped, the car gives a quiet “beep” that sounds like the horn. My passengers have heard it also. Is there a short somewhere? Could it lead to further problems? ---

Quiet beep that sounds like the horn? Every car I ever drove with a working horn, it was never quiet. I suspect it is a beeper under the dash, such as a door closed beeper or a fasten seat belt beeper, or a key left in the ignition beeper, that is beeping because of a faulty operating switch, in the door, seatbelt, ignition etc. Most likely you only hear it when stopped because you are not as distracted by traffic and road noise. ---

Thanks, your answer sounds reasonable. I’ll have the mechanic check the operating switches.
