It's happened to me 2 or 3 times. Always fixed by turning off the ignition. just a gremlin.This morning I was driving to the gym and as usual put on the cruise control to avoid a speeding ticket. After my work out, I went to use cruise control and it did not engage. I turned the main switch off and back on and it still didn't engage. Stopped, turned the whole car off and restarted. Then the cruise worked. Odd? Anyone else ever experience similar or know if this is a sign of something impending......or is it just the full moon????
I've not told the dealer as I can't reproduce the problem.
I leave my cruise switch permanently in the on position, so I don't think it's anything to do with the switch itself.
Mine does it when the sun shines as well.
