2021 Ford F-150 Hybrid

When gearshift lever is in "DRIVE," it would not shift into "REVERSE" or "PARK." There were no warning lights. Gearshift lever would always move from "PARK" to "DRIVE" or "PARK" to "REVERSE." I was in traffic, I was unable to move the gearshift from "DRIVE" to "REVERSE" when I needed to backup. The only way to get the gearshift lever to move was to TURN OFF the vehicle while it was in "DRIVE" and on a 2021 F150, the gearshift lever will automatically move into "PARK." Then I was able to restart the vehicle and move the gearshift lever into "REVERSE." From "REVERSE" the gearshift lever would move into the "DRIVE" position. This failure resulted in my inability to control my vehicle when required. The dealership replaced a GEAR SHIFT ASSEMBLY to resolve the problem.

1) Vehicle acceleration delays. From a stopped vehicle condition transitioning onto highway roadway the vehicle failed to accelerate for several seconds. Again from stopped or low speed idling condition following a turn there occurs a 1 to 10 second failure to accelerate. 2) Failure to accelerate puts into question the safety of anyone in any vehicle within proximity to the malfunctioning vehicle. 3) Our personal vehicle problems has not been observed by any dealer, we have not presented it for diagnosis at this time. We are actively monitoring and posting to the [XXX] group about our experience. A ford dealership employee has an advanced Ford factory representative working on understanding the problem. Otherwise, it seems, no one currently understands the issue as yet. 4) Our personal vehicle has NOT been inspected by the Manufacturer, police, insurance reps or others at this point in time. 5) There has never been a warning lamp or message in regard to this acceleration failure. The failure is not predictable in nature. We have never experience such failure at highway traffic speeds. It most often presents when accelerating from an idle or low speed driving condition, often following a turn.

The truck is a 10-speed and the 10 gears are displayed on the dash. While driving down the road, the gears start to disappear. Once it gets to the gear you are in, it will force a hard downshift. It will continue to force a downshift into first gear and the truck stops with hard engine breaking. The first time (6/26/2024), I was almost rear ended. If you put the truck into neutral, all gears reappear and you can start to drive again without any indication of transmission issues until the gears start to disappear. Ford dealership has attempted to fix multiple times, but continues to happen. If not expecting, is very sudden and can cause rear-end collision or loss of control. I have a detailed record of the incidents (date, speed, mileage, etc.) as well as multiple videos demonstrating the issue. Not able to upload videos.

Check engine light on . Ford says exhaust heat exchanger bypass valve. I see online multiple people are having the same issue . Seems to be a common issue with this vehicle . They are saying it’s not a part of the power train warranty although it’s attached to the power train . This is a safety issue. With the amount of posts about this issue I’m surprised it isn’t a recall already.

While operating the vehicle, I shifted into park, using the console shifter. With no warning, the vehicle malfunctioned. The console shifter indicator light started blinking next to the "P" and it would not let me shift back into gear. I turned off the vehicle and tried to restart it in the hopes that it would clear the error. The vehicle engine would not start, and told me to shift the vehicle into park. I was unable to shift the gear into park or any gear. A tow truck driver came and we were able to force the vehicle into neutral for towing, but the vehicle's parking brake engaged and would not disengage. Every time we turned off the parking brake, it immediately turned itself back on. Thus, we could not push the vehicle into a better position for the tow truck to get the vehicle and the tow truck operator had to drag the vehicle with its back tires not turning. At the Ford dealership, a service employee inspected the vehicle and said there was no physical damage to any component and that some kind of electronics error had caused the fault. He said it was a known issue with F150 transmissions and that a Ford service bulletin indicated a 6-hour "module" reprogramming process was necessary to make the truck operable. He said that it could recur. I spoke to Ford customer service. A representative there confirmed that this is a known issue with F150 transmissions but that no recall had been made. She also stated that Ford did not know why it happens and that, even after being "reprogrammed", it could happen again. Based on my experience and discussions with Ford, the F150 can suddenly become inoperable and (because of the parking brake) immovable. Thankfully, the transmission error occurred for me in a safe location near my home. It could have been very dangerous had the vehicle become immovable in an unsafe location or far from home or help. I am concerned it will happen again. The vehicle is currently at the Ford dealership in Grand Ledge, MI.
