This problem started a few months ago, and is getting progressively worse. A few miles after I set the cruise, it disengages. Once it has done this, I cannot reset it again without shutting off the vehicle and restarting it. Today, of course, the symptoms were marginally different. This time, I was able to reset it a second time while still on the road, but not a third time. On the trip home, it wouldn't engage at all. Thought I would check and clean the connections, but can't even find the unit under the hood. I guess they look much different than the old style with the vacuum hoses and chain! This is getting to be a real PITA, as I use the cruise control most of my driving time. Any suggestions?
