Similar to NHTSA id# 11290551, I too experienced sudden acceleration of my vehicle over the set speed on the cruise control systems in both medium (35-45mph) and highway (50-65mph) speeds. I'm the original owner of the vehicle, currently under 15K miles. Periodic visual inspections by owner, all vehicle maintenance performed by dealership as per owner's manual. While I never let the car take over the driver, it concerns me if this happens with my wife driving it as she may not have the same thinking that I do. Aside of that, the adaptive cruise control feature is inconsistent in detecting vehicles while switching lanes or in flat surfaced curves, regardless of the weather (happened multiple times during clear days and under moderate rain). This causes the vehicle to accelerate so it returns to the set speed. While the feature works ok most of the time, those inconsistencies can cause severe problems on highway speeds - which is the place they are most used at. Once again, while I feel I am always in control of my vehicle, I get concerned for my wife. She does not do highways or drives longer than a 10 miles radius to a few known locations by herself. By the few times I experienced the reported, I've considered if the vehicle with the claimed added safety features were worth the purchase and are truly ready for wide adoption.

The contact owns a 2019 Ford Fusion. While driving 35 mph with the cruise control engaged, the contact applied pressure to the brake pedal. Upon releasing the brake pedal, the vehicle accelerated on its own at a high rate of speed. The failure occurred twice and the speed reached exactly 71 mph. There were no warning indicators illuminated. The vehicle was towed to ken grody Ford carlsbad san diego (5555 paseo del norte, carlsbad, ca 92008, (760) 438-9171), but was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 350.

With cruise control set, pressing the + button and holding for a few seconds to increase the speed a few mile per hour will cause the vehicle to continue accelerating until the 'cancel' button or the 'off' button is pressed. Pressing the brake pedal will also stop the run away acceleration. During the run-away accelerating, pressing the + button or the - button will not stop the acceleration. Additionally, with cruise set, pressing the - button for a few seconds will cause a run-away deceleration. The vehicle is presently being looked at by the dealership where it was bought. In the mean time, I was given a 2019 Fusion hybrid as a loaner vehicle and that cruise control does the same thing: Run-away acceleration and deceleration when pressing the + or - button. The vehicle was checked many times and was cruising anywhere from 50 mph to 70 mph when the + and - button was pressed. I noticed that the run-away deceleration was quite pronounced compared to the acceleration.
