When turning right there was a complete loss of power with no response from the throttle it was just stuck coasting at 20klm hr. For 20 seconds or so then throttle kicked in and normal operation again. This has happened twice now in the past week. Very dangerous especially when turning into traffic.

Despite having been told my truck was fixed at a dealer shop, my truck still displays an absence of forward propulsion when applying the gas pedal and trying to accelerate from slower speeds. This has happened when trying to make a left or right turn when there is oncoming traffic. Sometimes this happens while trying to accelerate on the on-ramp of a highway to get up to normal piste speed limits with traffic very fast behind me. The dealer I took it to said they fixed the issues. Luckily I can apply the Manual mode with a button, but this is distracting when trying to look for the button, and the issue comes back in Automatic mode.

Rear axle failed while driving. Had vehicle towed to Malloy Ford in Winchester, VA. They replaced the failed components, at no cost. When I asked about reimbursement for towing, they were not able to assist me in filing my claim for towing reimbursement. I contacted FORD Customer Service, who said they only way they may help me is if I return the vehicle to Ford Service (must be in their possession) and have Ford Service contact them directly and ask for "reimbursement assistance" by 16 Jan. However, stated there is absolutely no guarantee they will reimburse towing. Are you able to assist me? The towing cost was $185.40

The vehicle fails to acclerate. When pulling out into a street the vehicles accelerator became completely unresponsive. The vehicle was stuck in 2nd gear going about 8mph and the vehicle would not accelerate, I even push the pedal all the way to the floor for several seconds with no response. I had to come to a complete stop in the middle of the street for the truck become responsive to my inputs. I was nearly rear-ended due to this issue.

I was pulling out into traffic, I eased out to make the turn, when I pressed the accelerator in order to merge to traffic speed, the truck did nothing. It did not stall, the engine was running, but it would not go. The transmission did not act like it was in gear, it is an automatic. I could have been hit by other cars by having my truck sitting in the road. The problem has occurred twice, but I cannot force the issue. it occurs randomly. I am calling service center today 12/17/24 to have it looked at. Vehicle has had the transmission replaced by manufacturer at a factory authorized dealership. There were no warning lights or any indications that the truck was malfunctioning.

Vehicle regularly loses all throttle response for 5-10 seconds, usually around corners at low speed, but sometimes while driving straight. This lack of response is alarming when pulling into traffic. There is no light on the dash indicating traction control is activated.

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.

I just want to provide support for others that have this safety issue, as my 2021 F150 Powerboost also has this issue. When making a turn, usually a righthand turn, onto a busy road, the vehicle will fail to accelerate. The delay is not turbo lag, but more so a dead space or lag of any response from the power train. I have found that if I disable the advance trac and traction control, the issue is no longer present. Just wanted to reinforce the confidence at the start and how dangerous it is. You get this false sense of security that the truck is going to accelerate a certain way, then falls flat at a very risky time. FYI, I am running the latest PCM code and modules updates available from Ford, via FDRS. Here are other examples if it helps: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After a few hours of parking in a lot, or overnight from my garage I lose accelerator response when trying to accelerate. I will lightly use the throttle to pull out of a stop, turning right, and the truck will not accelerate for up to 12 seconds even with steady throttle input or pumping the throttle. If I press the accelerator to the floor it will shorten the delay time, but will surge at full throttle. Twice I have pulled into traffic, but truck will not accelerate and I am almost rear ended or cannot cross an intersection with traffic come at me. This is a serious safety issue. Dealer has not been able to replicate or repair. This has been happening for 6+ months.

After a right turn in a residential street, I pressed the accelerator to progress on the roadway. The truck did not accelerate, so I looked at the tachometer and observed it above 0 and below 1,000 rpm. The engine was running, but unresponsive despite pumping the accelerator. While rolling at 5 mph I shifted the transmission to neutral and continued pumping the accelerator. There was no response for the next 200'. Finally, the engine became responsive and ran normally. It runs normally now. I cannot reproduce this issue. I called the Ford dealer service on 8 November 24 at Noon and they said "watch for the issue". I expressed that in traffic, a suddenly undependable engine is a serious concern. The accelerator/engine was unresponsive for a continued period of time. The gas engine was in control. There was no check light/warning light. The Ford dealer inspected the telemetry of the vehicle remotely and no anamolies were observed. The dealer declined to inspect the vehicle since the issue is not reproducible.

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.

At 30k I noticed the transmission start shifting hard especially when down shifting. I called the dealer and expressed by concerns when doing my normal oil changes. The dealer said it was normal. Now at 42k the truck skips 2nd gear and when shifting between 3rd and 4th it hits hard. Also an independent mechanic shop said the engine is making a weird winding sound. Sounds like the barring in the turbos are going. Again I tell the dealer and they said it's normal for the 3.5 ecoboost to sound like that. Currently it's at the dealer getting the transmission worked on. I know I will be having engine issues, that sound is not normal. I want it on record that it started happening around 30k.

When attempting to accelerate the vehicle hesitates for several seconds as the automatic 10 speed transmission attempts to engage the proper gear. This is intermittent. It has happened numerous times and is particularly dangerous when attempting to merge onto a highway or turning in either direction at an intersection.
