When accelerating from a low speed, accelerator does not respond.

- Pleasanton, CA, USA

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.

I've experienced the loss of power during hard acceleration. Right hand turns from a stop feel like the engine has stalled and rolling right hand turns are becoming increasingly more dangerous. Most recently as I was merging onto a highway. Pedal to the floor, the truck initi9ally accelerated for a couple seconds until it stalled to make the truck not only not accelerate but almost made it feel as if I was breaking. This is very dangerous.

Cruising highway speeds, when accelerator is pressed to gain speed, make a pass, ect the transmission downshifts into 3rd gear, engine losses all power for 4-8 seconds while accelerator is held down. I-??ve almost been in several accidents due to expecting a vehicle to accelerate and nothing happening and traffic

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.

Rear axle seal busted because the rear axle hub bolt broke. Dealer indicated this cause the axle boot to bust allowing water into the differential. Dealer stated parts for recall aren't available and/or are on national back order. Ford estimates a fix will be in place 1st quarter 2025. So I am out of a vehicle until this time. Ford refuses to cover a rental.

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.

I started to pass a vehicle, when I tried to accelerate the vehicle lost all forward momentum like it was in neutral, I pressed the gas to the floor and then engine did not raise the rpm-??s and no forward increase in momentum, I then let off the gas, and then reapplied full gas and it very slowly started to move forward again. This almost caused an accident as I was passing on a 2 lane road over a broken yellow line, it just fell flat on its face.
