While driving with cruise control set at 65mph the vehicle will maintain set speed for a undetermined amount of time at which point the vehicle cruise will jump to a very high setting of 88mph....forcing me to shut the system down...this happens frequently and I can't determine what sets it off. Ford Dealer can't find anything wrong. Also the lane assist will constantly warn of not holding the wheel or lane in fractions forcing me to shake the steering wheel to let the system know I'm holding the wheel.

My Expedition has adaptive cruise control. I was driving on the interstate at around 65 mph with the adaptive cruise set. I was raining, so I set it to max range. It worked fine for the first few minutes of rain. As cars started to slow down, mine sped up and put me in an extremis situation where I had to forcibly apply the brakes. It was following the car in front of mine fine at around 55 mph, but then sped up despite the car getting closer as if there wasn't a car there. Only after I applied the brakes did I start getting an error that adaptive cruise and collision assist were not working due to a sensor being blocked. I've driven in rain many times and have never had this error. As far as I can tell the forward sensor failed due to moisture and instead of the adaptive cruise turning off, it actually caused the vehicle to accelerate since cruise was set to 65 mph. Sensor failed in a 5 minute rain storm. Software design does not fail safe, but rather the opposite.

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.
