A few days ago my 2013 Prius III (126,000 miles) started beeping while parked, power off, and in the garage; beep lasts about 1 second and recurs every 31.35 seconds. Approximately. I replaced the ORIGINAL 12v battery a few weeks ago; all has been well till this point. Yesterday, I disconnected the 12v for 20+ minutes and the beeping persisted. I then disconnected the electric engine battery while the 12v was still disconnected and still the beeping persisted. Let's hear it for persistence! Can the solar panel produce a beep? What might be happening? The beep is definitely originating on the outside but I can't definitively locate it.
Generally, I leave the solar-powered fan off except when parked outside. So, sometimes it's on, sometimes off.
There was a thread a lot like this not long ago, where it eventually turned out someone had left some kind of device behind in the car, and that was beeping. I'm often frustrated by very high-pitched beeps—extra difficult to hear a direction, especially when they're brief.
Just listen to WHERE the beep is coming from. Follow with your ears, the rest of the body will follow. Then you'll find it. It may be under the car. Or, perhaps someone on put an air tag in your car and the are tracking you. Possibly to steel your car, or rob your house. Maybe someone dropped there air tag in your car and it fell behind the seat and the have send a message to beep so they could find it.
Umm, yeah. From the "Well, not the first time I've been an idiot" department: it turns out that my sister who went on vacation and left her Tesla in the same garage as my Prius, well, it's her car that keeps beeping. DOH! Now for sure I'll never get a Tesla. And what heretofore had been extremely fine hearing on my part, even finding a ticking watch buried under clothes, is now deemed questionable. My apologies for the trouble. Perhaps it's now amused a few people.
If I spray my 2013 persona with the garden hose beeping will start outside the car some piazo electric beeper buzzer noise maker goes off I'm not sure why because water's hitting the car? And that's about it I think the remote might be in the car the car is off for sure and the windows are up It's not in the accessories mode or anything like that It's completely off but the remote may be in the cup holder not in my pocket The car is not locked or anything like that when does up and I'm hosing it off and then all of a sudden béeeeeeeeeeeeep.
Me thinks that has something to do with the touch lock being wet and you are within the three-feet-zone of receptivity or because the fob is in the car, the receptor thinks that you [but it's the water creating the connection] are trying to lock the car and that's a no-no. 1970s NASA technology it's not.
Since: "...I disconnected the 12v for 20+ minutes and the beeping persisted. I then disconnected the electric engine battery while the 12v was still disconnected and still the beeping persisted." It could NOT be the car. It had to be something unrealated to the car. Since there was NO power, it couldn't make any noise.
