Cruise control has gone insane one day when driving down the road, the cruise control decided it needed to switch on and that I should be going 50+ in a 35 mph zone. This is on a 2002 Pontiac Sunfire with 5 speed manual transmission. If I depressed the clutch, the engine of course raced as hard as it could. Applying the brakes failed to disengage the cruise control; manually switching the cruise control off failed to disengage; even turning the engine off (by turning off the key) failed to disengage it! luckily, I have a manual transmission, and kept a cool head, so was able to keep the car under control. I pulled over to the side of the road and turned the car off. When I started the engine back up, the cruise control was still engaged, for it was racing as hard as it could. I turned it back off and let it sit for a bit, hoping that once it sat for a bit, all would be well. After about 10 minutes I turned the key and it was fine, except that once I got back on the road, the cruise control would not come on when I tried to switch it on. Ever since, the cruise control will not come on when I try to use it and occasionally. Randomly comes on by itself when I am not trying to use it. The cruise control has come on by itself at least a half dozen times.
