I'm assuming you don't use the cruise under 30 MPH...and don't rest your foot on the brake pedal. Your problem may be in the brake light switch circuit. Have the switch checked behind the brake pedal.
(This may sound odd, but on the HHR's if more than 2 of the five high mounted rear brake lights are out, the cruise will act up.)

MY CAR ACTS LIKE THE SWITCH IS BAD OR NOT GETTING GOOD CONTACT
change the brake light switch, then see what happens.
