Long beep while driving 2008 Prius

Hello everyone,

So I was just on my way home and my Prius suddenly did a long beep without any symbols appearing on either the screen or the dash (as soon as it beeped I immediately checked the screen).

It was a long beep for about 30 seconds or so.

I was driving downhill in the rain, my 2008 Dutch (Netherlands spec) Prius does not have keyless entry/driving. So the fob was in the slot.

I was not breaking and in fact my foot was off the accelerator as I was going downhill at 70 KM/h. The window wipers were on and the rear window & mirror defroster was on (for a second cycle, as it goes off automatically after 15 minutes).

So yeah, I am completely mystified by it as there were no symbols on dash or even a message on the screen. My car does have front and back parking beepers but in the rain I always have to turn off my front beepers anyway so those were off, and the back one normally only activates when in R.


Regards,
Cole

 

Hmm that does sound possible, if it happens again I will check all the doors.

No for sure was Prius

Thanks!

No as mentioned no symbols on dashboard. That is also a different beep sound, it is not a solid beep but a beep that goes on and off very softly at first before becoming a rapid loud beep.

 

Update:

I found by chance what the issue was.

It was the warning sound that the parking beepers (both front and back) were deactivated due to fault in system. It only happens in the rain and last time it happened I did not use the parking beepers to park, but day before yesterday I did and then I realised that both front and back were no longer working.

When the weather dried up again yesterday and I used the car the beepers worked again.

Seems the rain is getting somewhere where there is an open wire or connection and it is stopping the beepers from working.

Hopefully the garage can find where the fault is, any tips here would be greatly appreciated as then I can already look myself for the fault location.
