2025 Ford F-150 Hybrid

Vehicle demonstrates an intermittent lag during acceleration, particularly during throttle position changes. Typical throttle response is appx 0.5s as measured by stopwatch. When the issue is replicated the delay can exceed 1 second. This is most concerning during situations where moderate to brisk acceleration is needed at a specific time such as turning across traffic at an intersection or merging with traffic flow with a large speed disparity from one lane to the other. Vehicle has been taken to multiple Ford dealerships multiple times. The ECU and TCU have been reprogrammed and the situation does not change. Dealership has noted an issue one time but otherwise claims that they have not been able to show the issue to be out of allowable parameters by Ford. Numerous forum posts online discuss the same symptoms and comment similar findings by Ford dealership techs. What they can readily replicate is understood but considered "normal". This behavior has created 2 different situations that nearly culminated in severe accidents with myself driving the vehicle, one time with my child in the seat exposed to oncoming traffic when the accelerator lag caused a severe situation. The first severe situation was crossing traffic outside of my child's school with oncoming traffic having to slam on brakes in order to avoid the collision. The second situation happened while merging lanes on a highway going from ~45mph up to ~60mph and almost caused the neighboring lane to rear end the vehicle. The dealerships have noted the delay exists but to be considered "within allowable limits" when it happens. No warning lamps come on as a regular pattern. This pattern first appeared when the vehicle was less than 500 miles on the odometer. The first dealership ignored the information.
