Cruise control

I have a 2005 Dodge Stratus. 40,000 miles on it. I have been having issues with cruise control. Some times it will turn on but not set the speed. Some times it will work just fine and some times is will turn on and then off within a few seconds. Is this something I should worry about. Is there something else going on?

A common problem for CC’s is the disconnect switch on the brake pedal needs to be adjusted. Sometimes the switch doesn’t open (I think it is open, it may close) when the pedal is returned to normal.
