Humming sounds and mystery wires

#1
Hi

I just bought a certified corolla 2016 LE. I seem to find some problems with the car.

Problem 1: I was waiting for someone today, so I shifted to PARK and lifted up the handbrake. Then, I heard the regular humming sounds. The sounds were like the engine sound when we hit the gas, but gentler. The sound lasted 10 seconds, and stopped for 20 seconds, then started again.


Problem 2: I found wires next to my brake pedal. Is it supposed to be like this? Please see the picture.

This is my first car, I am still learning "car terms". Thus, my descriptions may be somehow confusing. I apologize for the inconvenience and thanks for your help!

Take it back!
Looks like someone has done some shady mods to it and that’s why they sold it. (How’s that for alarming!)
Have the dealer check it out.
I hate how dealerships advertise as “Certified Pre-owned”. Usually these are just lease vehicles that have been turned it.
