Pretty sure all you're hearing is the truck purging the lines of DEF. It does it a few seconds after you shut the truck off to clear the lines in case it freezes. It will also do it if you just have the aux power on as that will prime the lines. Its kind of like a suctioning noise, 2-3 times as you said.
2019 F150 Lariat Chirping
Hey everyone new to the forum. I've had my truck since it was new in July of 2019. Recently hit 48k miles and it is now "chirping" when you shut the truck off. It will also happen when you enter it after its been shut off and sitting. I have never noticed this before and not sure if anyone else has run into this. Seems like it will make the noise 2-3 times then stop. I asked the dealer to look into it when it went in for a recall this week and got the typical "we didn't hear anything."

The chirp I hear comes from the internal sound system, the same beep you hear when using the touchscreen. Definitely not an external sound.Pretty sure all you're hearing is the truck purging the lines of DEF. It does it a few seconds after you shut the truck off to clear the lines in case it freezes.

Oh I see... did you leave your lights on? haha. If you have forscan you can maybe try resetting the APIM module of something. No messages anywhere?The chirp I hear comes from the internal sound system, the same beep you hear when using the touchscreen. Definitely not an external sound.
@Marc21 - you mean something like this?

All depends on what your definition of a "chirp" is -- this one reminds me of a simulated European police siren...
You can posts videos here -- would it be possible for you to record a video with your phone of the sound you are describing so that the rest of us know exactly what chirping noise you are hearing, as I initially thought the same thing that @Laytunes brought up...
Video (w/sound) is also an excellent way to combat your dealership's "We don't hear anything..." lame excuse for not even attempting to diagnose...
Guessing this is a generic F150 issue and not specific the the F150 PSDs (PowerStroke Diesels) so we can lean on the much larger F150 forums for help.
Thanks in advance.
BTW - welcome to the forums, as I see this is your first post, so welcome aboard!

According to my 2018 F150 Owners manual, the following is the list of audible warning alarms:
AUDIBLE WARNINGS AND INDICATORS
The number of chimes and type of chime should help us track down what your issue is, which is why I asked for a video of what you are encountering.
If you have any of these audible warnings going off, an OBD code may be thrown and can be read using a OBDii code reader (something like my Edge Insight CTS3 monitor or a diagnostic tool) or via FORScan.
