General: While driving this rental vehicle over the span of three days, I noticed and confirmed over a dozen times that the vehicle's speed control would dramatically increase with NO driver input or actions. Specific: The vehicle's cruise control would be on and active, set at various speeds; 55, 60, 65, 70, 75 (long, straight road with varying speed limits). In different circumstances (sometimes when being overtaken by another vehicle, or cresting a hill or when beginning to climb a hill), the speed control, while set would immediately, with no driver input other than light steering INCREASE to 15-30 mph above the speed at which the cruise control was set. Over the period of three days of rental I was able to verify this behavior many times and I was able to capture a video that shows the speed set increase from 65 mph to 90 mph immediately, and the vehicle would begin aggressive acceleration. I have a clear video of the steering wheel and gauge cluster that I cannot attach to this report, but will email upon request. In the video, the malfunction is at the 13 second mark. In this video, the speed control setting increased from 65mph immediately to 90mph and the vehicle started accelerating. Switching the speed control off, or tapping the brake ceased the acceleration, as expected. Vehicle was reported to National car rental and an attempt was made to report it to Ford. Because it was a rental, I am unaware of any corrective action or inspection that may have, or may take place.
