I was attempting to leave a parking spot when while maneuvering the vehicle it suddenly and unexpectedly accelerated to a high speed into a tree. There is a police report and security video as the incident took place in a hospital parking lot. The truck is totaled and settled but insurance company not interested in liability. My wife and I were injured. I have no idea or explanation for the sudden acceleration. Nobody is investigating if there was a vehicle malfunction or not. I just want it documented somewhere in case it is happening a lot. The crash was violent and occurred from a near complete stop on a clear day with no distractions.

In 2024 Ford introduced a turn detection in the F-150 (and other Ford vehicles). This feature extends the adaptive cruise control which recognizes speed limit signs and dynamically adjusts the speed control to comply with speed limits. This added Turn Detection, detects curves that have the Yellow highway curve warning signs with the small orange suggested speed limit sign below and automatically slows the vehicle down to at or below the suggested corner speed. The vehicle slowly goes through the curve and then rapidly accelerates out of the curve back the set cruise speed. This causes a huge safety issue especially on highways with higher speed limits where the suggested corner speed is substantially below the general flow of traffic. First Example of safety issue: When driving on a highway with a higher speed limit (especially 60mph or higher) with cruise control set for example to 65mph (speed traffic is naturally flowing at), entering a corner with a suggested speed sign of 55mph causes the vehicle to brake unexpectedly bringing the vehicle from 65mph+ to 52mph rapidly. This unexpected braking cause vehicles following to be caught off guard and in multiple cases almost rear end my truck. Second Example of safety issue: When driving through canyon highways in Colorado where almost every corner has a suggested corner speed, the truck is constantly braking hard into corners and rapidly accelerating out of corners. With the corners so close together in these canyon highways it creates a situation where the truck becomes difficult to steer and keep on the road because of the numerous and rapid speed changes which is very dangerous in a canyon environment. This issue has been problematic since I purchased the truck new, this behavior is acknowledged by Ford when I took it into the dealership to get it addressed and they have indicated that the functionality is working correctly and there is nothing they can do to correct it even though it's a safety issue.

Multiple times the acceleration has stuck and would not release when hitting the brakes. I have to stick my foot under the accelerator and lift the petal to get acceleration to stop. Without physically lifting the petal it would appear this continues indefinitely.
