Major safety concern. The vehicle gets stuck in first gear while the engine is running and the brake is released. It used to only do it when the vehicle had the engine auto-shut off featured turned on but now it does it permanently. I stopped driving the vehicle because there is a high risk of causing an accident.

This has happened multiple times now. Always happens at high speeds (greater than 45 mph). I will be driving on a highway when I unexpectedly lose the ability to accelerate. First noticed in correlation with the collision detection feature showing on the display as NOT FUNCTIONING. That does not happen anymore, but I still lose the ability to accelerate periodically. Once I can safely remove myself from the flow of traffic and stop/restart my car the issue is resolved. Makes me believe this is electrical/computer origin. The vehicle was taken to the dealership twice where they claim -??cannot duplicate-?? but are willing to replace any item that I will pay for out of pocket. The dealership does not want to honor my extended warranty. The vehicle was purchased new in 2019. Within one year they had to replace half my engine (which they decided to do without warning when I dropped off for an oil change). The vehicle was stolen in 2023 (recovered by me in under 24 hours). Multiple cosmetic issues were repaired by a Ford authorized service team. This issue presented about 1.5 months ago 4+ months after the vehicle was repaired.

Continually receiving "see manual" message while driving, will intermittently appear and disappear. At times, the plug-in battery will completely stop working while still charged (more frequent in colder weather). It always resets/removes the "see manual" warning upon next vehicle start. Engine shutters and pings when turning the car off and is rather intense and seems potentially damaging. When driving at low speeds and when changing speeds, engine will not shift correctly when accelerator is pressed, and then will suddenly engage and lurch forward. And when slowing down braking system is not consistent, often have to depress brake harder than normal. Hybrid battery will also stop working when "see manual" message is on. At times the check engine light will come on, code P0B24, checked by Ford Dealer (Norm Reeves, Cerritos, CA) on 12/21/23, 'Hybrid Battery A voltage unstable'. Known recall but they have no fix. Dealer says corporate office has to authorize any sort of loaner car or arrange for rental car, however website says "contact your local dealership directly" when I enter my info for the recall. Called Ford corporate on 1/15/24, their answer is "we have no fix for this" regarding both fixing the car and providing us with a working vehicle. They would not take down any of our contact information or give us any other outlet to contact.

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.
