2021 Ford F-150 Hybrid

My truck because of the transmission and it's "powertrain" faults; puts itself in low power mode. I can be driving fine, stop for a red light, to turn a corner or before pulling into oncoming traffic leaving a parking lot etc and without warning, no power. It won't go over 5-10 miles an hour. You have to let off the gas and give gas sometimes more than once to get the truck to finally pick up and go. I have almost been hit countless times because I suddenly couldn't get out of the way of oncoming traffic. The dealer has confirmd to me a few times that this is a transmission issue that is sending my powerboost into low power mode. I believe he said the tech that drove it said it was dangerous; but a known issue. Started a few years ago and doesn't happen all the time. Occurs sporadically and lately more and more frequently.

The contact owns a 2021 Ford F-150. The contact stated while driving 45 MPH, the vehicle stalled. While at a stoplight, the accelerator pedal was depressed, but the vehicle failed to move or respond as needed. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the local dealer, who informed the contact that the failure might be battery-related. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that there was no warranty coverage on the vehicle. The failure mileage was approximately 140,000.

Leaving a parking lot and after turning right, the truck failed to accelerate for over 800 feet. Over this distance, the accelerator was pressed all the way to the floor and the truck stayed stuck in 2nd gear, slowly increasing from 2,000 rpm to 2,500 rpm, and from 17mph to 21mph. After this time, the accelerator pedal was pumped, and the truck responded with normal acceleration. This is not the first time this truck has had the issue, but it is sporadic, and almost always when turning right from a rolling stop. This has a high potential of causing accidents when trying to turn on to a road with higher speed traffic and unable to accelerate as expected. There were no warning lamps or messages indicating an issue with the vehicle. The issue is not consistently reproducible for Ford to inspect it, but it does happen a few times a month.

Unintended acceleration event. Initial condition: Cruise control off. Steering wheel turned 270 degrees ccw, turning left, at a complete stop, released brake, rolling forward at less than 5mph in a confined parking garage. Continuing to turn wheel to left, my right palm accidently engaged the cruise control button on the steering wheel. Cruise control automatically set to 15mph and began to accelerate. I was able to engage the brake again in enough time to deactivate cruise control. This is not the first such incident I've had where the cruise control is accidentally engaged and begins accelerating the vehicle to 15mph. Anecdotally, they have all occurred during left turns. Seeing how it engaged today, I can now understand why I couldn't figure out why it was happening previously. Due to accessibility issues, I typically turn with a single hand while allowing my other to remain capable of grabbing to maintain control. How easily my palm brushed the cruise control unintentionally was shocking.

When making 90° turns such as an immediate right turn or a left turn across one lane, gas pedal becomes completly unresponsive halfway through the turn for approx 3 seconds. Occurs about 1% of the time but drastic when it occurs. Almost multiple accidents have occured with oncoming traffic almost t-boning me when making left turns or being rear ended on right turns: people don't anticipate a vehicle stalling and slowing down when entering traffic and people have swerved into other lanes or the shoulder to avoid a collision. When this occurs, it is like the vehicle goes brain dead, the gas pedal can be pushed to any threshold including floored with no change to speed; rpms dont even increase. Vehicle has been through Ford troubleshooting multiple times and at one point early on, had a Ford engineering/ specialist working remotely with the dealership. Findings from this specialist: two upcoming ota updates will be released that will resolve this concern. One of the updates was in regards to the trailer brake module and the other something else as equally ridiculous as not pertaining to my issue. OTA updates came and issue never went away. Years later, multiple appointments with techs saying unable to duplicate. Dealer now saying they have no record of working with a specialist even though I have the service records from them stating this and electronic communications from Ford regarding this. The issue is not resolved and still occurring. Vehicle now out of warranty so likely will never be repaired. Not faithful in thinking NHTSA will care, they didn't care when this vehicle had complete brake failure at 7k miles which was later found to be due to incomplete or bad programming, but maybe this will help others know they are not alone if experiencing this issue.
