2006 Kia Sportage

Hello everybody…new to this, so I apologize if I do something wrong (and a relatively new car owner, so I don’t even know where to start)! There are few things that keep happening to my car, and I’m wondering if they are all related. If so, does anybody know where I should start?

1st: the rear brake lights are on the fritz. Sometimes they all work fine, sometimes the left side will work and not the right and vice versa, and sometimes they won’t work at all. I’ve already replaced the bulbs, but that’s not it, they still do the same thing.

2nd: The ESC (stability control) light comes on at random. And pressing the button will not make it go away.

3rd: The cruise control works at random. Also, it won’t work if my headlights are on.

Are all these related to one common system in the car?

Thank you for any ideas, suggestion, help, etc. you can offer

I seem to recall the Kias have fairly long warranty coverage. Isn’t your vehicle still under warranty?

I would start with the brake light switch.
