Why are laser beam sounds coming from my dashboard?

What is your question?

I recently purchased a 2008 Toyota sequoia with 95,000 miles. All was fine at first but lately I will hear 10 laser beam sounds from under the driver's side dashboard. It started with just 1 but progressed each time I started the car. It is now at 10 laser beams. There are no warning lights accompanied with the sound and the car runs perfectly. I will also mention that the sound comes after the car has started and the radio, air, etc has started.

What makes this problem better or worse?

nothing changes the problem

How long has your 2008 Toyota Sequoia had this problem?
