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.

Ford Motor Company has issued a safety recall, identified by letter NEF-107DG and recall number 24V-957, due to the potential failure of the CP4 fuel pump in certain vehicle models. The recall affects the following makes, models, and model years: FORD/F-250 SD (2020-2022), FORD/F-350 SD (2020-2022), FORD/F-450 SD (2020-2022), FORD/F-550 SD (2020-2022), FORD/F-600 SD (2020-2022), FORD/F-650 (2021-2022), and FORD/F-750 (2021-2022). This action addresses concerns that the CP4 pump may fail prematurely, potentially leading to engine stalling and increasing the risk of a crash. Notably, my 2021 Ford F-150 XLT with a 3.0L diesel engine is equipped with the same CP4 fuel pump as the models listed above. As such, it should logically be included in this recall to ensure consistent safety measures and address the risks associated with this known defect.

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.

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

OBDii reader which connect to vehicle ECM reads perfectly independently, however when connected to a state emissions inspection machine, machine indicates no vehicle information available and results in failures due to ECM not responsive. Ford says it is a known issue but will not replace ecm unless recall is issued.

Bought truck brand new. The axle bolt sheered off at 76k miles which is a common problem which ford has issued a service bulletin for repair. Ford claims my truck is not drivable due to the manufacture defect of the bolt either being cross threaded or overtightened from the factory. Ford is insisting I pay for the mistake even though it's a manufacture defect with a service bulletin for a repair. Ford is refusing to pay for the fix due to miles. Axles, axle shafts and axle bolts should not have to be replaced before the differential fluid does in the axle at 100k miles. They are claiming the extreme premature wear is my fault. The truck is bone stock. Ford case #CAS-43720120-D7H6Y6. Worst part is Ford dealership telling me claim was denied to only find out Ford approved the claim partially. The Ford dealership was trying to double dip on profits. Dealership is wade Ford.called up akins Ford in winder and they told me they would cover it.

I Have owned my 2021 F150 less than 2 weeks. I purchased the car with 200 mile on it. I was pulling out of a parking lot tonight and heard a clunk. 50 feet later the engine quit and there was a strong fuel smell and something was scraping on the pavement. We got out of the car and there was a big puddle of fuel under the vehicle. Upon further inspection, the front fuel tank bracket was unhooked from the right side and the front of the fuel tank was resting on the pavement. The fuel tube connection at the front of the gas tank was sheared off. We had the truck towed to Anderson Ford in Rockford, IL.
