Whistle noise / bird chirp on start up

What’s up guys. I just bought a used tundra it’s a 2018 sr5 with a 5.7. When I turn it on I get a whistle noise. It almost sounds like a alarm or bird chirp. When I turn it on to go to work I get 1 whistle. When I turn it on to come home I get 2 whistles. And every time I turn it on through out the day the whistles just add up. 3rd time 3 whistles etc. I’m not sure if I’m explaining this correctly but I can’t find anything on any forums. Please help lol

 

Does it do it when you first turn the key to the 'on' position, but don't actually start it? Does it have an aftermarket alarm?

 

How many whistles have you gotten it up to?

 

It only does it after the car is on. And it’s stuck at 4 whistles. I am going to contact the dealer today but it was a trade in so I’m not sure if there is any aftermarket work done to it.

 

Just a "cat call" because you drive a sexy truck!

 

Can you get a video of the sound, upload it to youtube and post the link here?

 

Ok so I figured it out. The dealership I bought it from had a gps tracking system on it. They forgot to register it as sold. The alarm was going off every time it was turned on and not in the lot.

 

Did you call the dealer about it? If not, that’s some great detective work
