steering wheel buttons for cruise short out

Very frustrating when you try to use the cruise control and it doesn't work by the push buttons on the Steering Wheel. This happens when the car is hot from the Weather outside. Living in Florida it is always hot and it makes things short out... Very frustrating and there is not a "fix " to the situation according to the warranty department and it "isn't a covered issue" I don't understand that at all.

volume level on steering wheel shorts out when adjusting

The Cars steering wheel features for volume control and for the cruise buttons do not work when it is hot outside. When you live in Florida it is always HOT. If you want the volume to go up, it goes down!
