It's hard to explain but ever since I have gotten my '20 I hear random faint sounds that remind me of a fax or old school modems. This happens when parked, unlocked or locked and all kinds of hours of the day/night.

I think it has something to do with the sonar system but have not had it into the dealer yet.

Has anyone heard these noises? I can't see how it would be normal, while it's not loud it's very noticeable.

 

My wife's rogue does this. No idea what it's from, but havent noticed it on my 18 maxima

 

Well, I had this happen in my 2002 Altima SE, I know exactly the sound you speak of, because that was exactly how I discribed it to service. The had to replace the Odom cluster (Not sure what it was called) and reprogram it with my mileage. I would assume it might be the same thing.......very odd sound.

 

I believe the turn signal blinker sound went away as well when this happens

 

I mean I am sure it could be anything but I notice it when I am up close and it sounds mostly coming from the front bumper/engine compartment.

I thought at first it was the sonar sensors with the keyfob in my pocket triggering when I get ready to wash it... But it happens when I am further away without the fob.

When I bring it in for its first oil change I will have the dealership look into it. It's very random but happens often enough that they will definitely witness it.

 

Mine was in the cabin coming from dash..no doubt. You got something else going on

 

Look in the glovebox. You might have some fax messages

 

If I had a glovebox I would check, but currently it is not installed. I removed to run power for a sub.

You maybe onto something. If I install a fax machine in its place, I might get a message from aliens.

 

How long does it go on for?
My BMW 5-series had this type of noise when it was powering down - or powering up - accessories while parked/locked. As to not drain the battery.

Possibly, it could be the Nissan Connect (telematics) system receiving messages (no joke). Remember, it's technically always active, even at low voltage - that's how it works (it's awaken by cellular, does something, then shuts off).

 

It's calling back to the mother-ship, sending reports and receiving instructions... for your upcoming abduction...

Mine clicks its solenoids like crazy in the side vents, every time I adjust the temperature, sometimes even without doing that. It sounds exactly like when some slimy alien blinks in a horror movie.

 

Messages from far..far..away?
