22' Corolla Cross Honking by itself
​
Hello all.
I'm not well versed in cars, and only know how to perform very basic maintenance on my vehicle.
Yesterday afternoon, I was sitting in my car with it running in front of my house so that I could download some footage from my dash cam when the car started to honk on its own. A long held honking. I panicked and turned the car off, which made the honking sound weaker but still continued. I put the car in reverse, and then the honking stopped.
This morning, when I turned the car on it did the same thing. Continuous honking, that got weaker when I turned the car off but this time shifting gears did nothing, but made it sound even weaker. And it stopped on its own after what felt like 20ish seconds.
Could the new dashcam cause this? I got it installed a couple weeks ago at a shop that does radios and the like. Since this is the first occurrence since getting it installed, that seems odd for me. That being said, I unplugged the camera from its power cord once the honking started, and it did not turn back on when plugged back in.
Does anybody know what could be causing this issue? I'd great appreciation any input.
Thank you!
