My brake lights are on when I go out to go to work, and as I'm driving down the road the brake lights will come on and the car will begin to slow down as if I'm pressing the brake. It does it all the time and I'm not even touching the brake. We just replaced the battery and the little fuse contraption on the positive battery post. What could be causing this to happen?

I just visited FL from GA in his heavy rain and I got a lamp for Engine. Engine starts delayed than usual with 2 or 3 seconds. What is possible root cause and I want to know I can have maker warranty.
My 2012 Kia Optima with 45k miles has an intermittent problem with the cruise control such that I can't set it with the switch on the steering wheel. When it fails it fails numerous times then all of a sudden it works. It has failed on 3 occasions and each time it has been raining out. I took my car to the dealer but it starting working when I got there. Since I don't have a problem with it disengaging when I put my foot on the brake I don't think it is the same problem that others have reported.
