While driving back to Arizona from San Diego, I was using cruise control. The cruise control would shut itself off repeatedly. No lights or warnings were associated with it, but it occurred several times on the drive. I took it to the dealership and they couldn't duplicate the issue. Keep in mind, I don't think they checked it, the mileage never changed on the car!! When I questioned them, they said the car didn't give a code so there was nothing they could do… pretty pathetic.
