I have a 2003 with 80K on it. The cruise control intermittently fails. It will be fine for a while, then cuts out and not reset. It will also spontaneously accelerate (slowly) on occasion until it is about 8 mph over the set speed, then it cuts out. If I try to reset it, it usually won't unless I shut the system off, then back on. After a couple times of this it will not reset at all. Sometimes when I begin the trip, I will use it and it will work fine for 30 miles, but when I make any changes, it may start acting up. It doesn't seem to matter if I use the brake, or cancel, or just shut it off. I've had lots of time to play with it as I've been dealing with this problem for a year or two. It'd be nice to know if anyone has found a fix for it yet. It seems to me that it would likely be the control module since it will often resume normally or fail with any of the possible options. Even when I try just using the cancel button, or just the power button, or just the brake. It doesn't seem to make a difference. Any advice would be appreciated.
