Problem with cruise control
I recently purchased a used 2017 Allegro Bus. This past week was the first time I had it on the highway and turned on the cruise control. It was set for about 60 and travelled about 1/4 mile before it just decelerated was on it own, rapidly, and would have continued to 0 if I hadn't intervened. I was told when I bought it that it was not adaptive cruise control, but even if it were it shouldn't do this. I tried it several more times, and it would go a variety of distances before doing the same thing. I didn't touch the brakes, gas pedal, or bump the steering control. It just seems to do it on its own. The little light that tells you that cruise control is on is very difficult to see in daylight, so I can't tell you if that was turning off or not. Was traveling on flat straight road. Any advice as to what I am doing wrong? I use my cruise control al the time in my car with no problems.
