Vehicle has completely unresponsive gas pedal for 3-5 seconds. Gas pedal is completely dead. This occurs randomly but mostly in a stop and start accelerating situation. Once the 3-5 seconds passes gas pedal responds normally. No codes generated during incident.

Vehicle suddenly overheated affecting ability to drive in traffic. Discovered coolant leak. The very issue determined by the dealership is the exact issue of a current recall. They say it’s not associated with my vin despite being the exact issue for the exact make and model. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

Exhaust Heat Exchanger failure with Powerboost engine at 55k miles. This seems to fail on nearly all Ford F-150 Hybrid Powerboost engines. Ford does NOT cover this repair under the Emissions, Hybrid, or Ford Extended Service plan. This is a known failure they are not covering and is documented in NHTSA SSM 52050.

Dealership replaced ecu and some switches to power bank and wiring harness behind headlight. Vehicle was returned 1 week later Drove it 2 days later for 10 miles same thing happened, Ford towed it to another dealership where they cleared codes, and they said they can't replicate, Vehicle was returned after a week. 2 days later I drove yo work and again iy happened stopped in middle of road blocking traffic. Was towed by Ford to dealership where they found over 20 codes, said they can't fix. Ford and selling dealer towed to selling dealer, where they cleared codes and said they can't replicate.

I signed title and sent it to selling dealer, they told me that fordwill not let them buy it back. Do I don't have my money or a truck now

This is the 4th time since purchasing the truck that this event has happened with time having the most severe results. When shifting from reverse to park the shifter goes into park and jumps back into reverse. First event (after exiting the truck) the truck rolled into a shipping dock breaking a taillight and buckling the rear bumper. Next two I had one foot on running board and one foot in the truck ant was able to hit the brake stopping the truck. This fourth event one foot was on the running board and one on the ground. As truck went back the door flattened me to the ground and the front tires rolled over both of my legs. The truck rolled up an inclined parking lot, across a busy road and down a bank. I was driven by ambulance to the hospital and then transferred and airlifted to trauma center at Ruby Memorial Hospital. After the second event the local Ford dealer said they could not duplicate the event. The brakes do not hold even though they are depressed and set when the shifter is shifted.

This problem has been ongoing, happening nonstop up to multiple times daily since Feb of 2022 and has spent now 70 days at the dealership in search of the issue. Luckily, the vehicle has not caused an incident yet, but I am afraid to drive it if I get it back from the dealer again as the issue has just gotten worse. The vehicle randomly while driving goes into a "limp mode" in which 1 of 2 things happens. 1) If unable to pull over immediately, the vehicle has very erratic throttle control and 2) the vehicle sometimes gives a warning about the "adavancetrack" system and will sometimes shift itself into neutral out of nowhere forcing you to coast to a stop no matter where or what type of street you are on. In researching this problem to help my dealer at first and now to try and protect myself while in a battle with ford, it seems to be a common problem discussed on many forums on the internet and facebook and seems quite common among the F-150 powerboost. Ford is refusing me a buyback at this time and ignoring the safety implications that my vehicle is having

My vehicle has the 3.5L powerboost motor and it has been leaking coolant from the egr cooler since I bought the truck in 01/2022. This has caused my vehicle to overheat and has left me stranded on busy highways.
