NHTSA Complaint #11683808 — 2020 FORD F-150

* What component or system failed or malfunctioned, and is it available for inspection upon request? Transmission/powertrain; currently available for inspection at time of submission * How was your safety or the safety of others put at risk? While stopped at stop sign/stop light, the vehicle would have long hesitation before advancing forward. I would initiate hazard lights to prevent driver behind me from crashing into the back of my vehicle. The vehicle would shift harshly and untimely as well as randomly downshift from 10th gear to 1st gear (x2 on 24Aug2025). I would have to pull vehicle off the road and when attempting to resume driving the vehicle would not move. The RPM’s would rev, however the vehicle would not move. I would turn off the vehicle and then restart it and the vehicle would move forward, resuming with harsh shifting. Loss of power, delayed and harsh shifting pose a safety hazard while the vehicle is in operation. * Has the problem been reproduced or confirmed by a dealer or independent service center? Yes; by independent service center * Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No * Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? First check engine light illuminated on August 16, 2025. (Please note the check engine light disappears once the vehicle is turned off and then restarted). I took the vehicle to AutoZone on 25Aug2025. The tech placed the code reader on the vehicle. 2 codes, P0734-00 and P07F7-00, ‘gear 4 incorrect ratio’ and ‘gear 10 incorrect ratio’ respectively were displayed. Vehicle taken to independent service center on 25Aug2025 who also placed code reader on vehicle. I am not in possession of that information at time of writing. Monthly ‘my vehicle report’ has been clear with no issues whatsoever noted until report dated 25Aug2025 (attached)
