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.
2021 Ford F-150 transmission complaints
Page 9 of 12: complaints 221 to 250 of 329, newest first, as owners wrote them.
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
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.
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.
The contact owns a 2021 Ford F-150. The contact received notification of the federal safety agency Campaign Number: 23V896000 (Power Train); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.
I contacted a local Ford dealership: Hempstead Ford, 301 N Franklin St, Hempstead, NY 11550, (516) 363-1579 to perform multiple safety recalls issued by the federal safety agency. The service department refused to schedule me for service because I did not buy the vehicle from their dealership. I reported this to Ford Customer Relations and was told that they cannot force the dealership to service my vehicle. I believe this is illegal.
The automatic 10 speed transmission 10R80 covered by TSB24-2176 will violently downshift or upshift causing passengers and contents of the vehicle to be thrown around the vehicle. This happens at random events, sometimes while accelerating, sometimes while decelerating, and without warning, which leads to violent decelerating and lurching on the road, which is a safety concern in heavy traffic. The transmission has been serviced 3 times by Ford of Homewood, twice under warranty and once out of warranty (60K powertrain) but there is no fix or remedy to repair this issue. I own several other identical 10 speed equipped trucks that operate fine, perhaps a bit jerky with shifting, but this truck is a safety hazard that cannot be repaired.
Good day, I am experiencing a leak from the front differential pinion seal on my vehicle. This leak appears to be a common issue based on reports from other owners in various online forums and owner groups. The front differential transfers power from the transmission to the front wheels. A leak from the pinion seal can cause a loss of differential fluid, which could lead to premature wear and eventual failure of the front differential components. If the front differential fails while driving, it could cause a loss of control of the vehicle and increase the risk of a crash or collision. This poses a significant safety hazard to myself, my passengers, and other vehicles on the road. I am requesting that Ford Motor Company acknowledge this issue and take corrective action by issuing a recall or service bulletin to inspect and repair/replace the faulty front differential pinion seals on affected vehicles. Allowing this defect to persist is unacceptable from a quality and safety standpoint. A front differential failure caused by this leak could result in serious vehicle damage, injuries, or fatalities. Please investigate this matter thoroughly and require Ford to address this safety defect before it leads to additional vehicle failures and potential accidents. Thank you!
Unknown which component is failing. It started with a rumble while accelerating or coasting but goes away when I shift into neutral so I believe that is the transmission. Other issues that are occurring randomly, speedometer will change indication to slower speed than I am actually going or it will drop to 0 while I am driving. Alerts and faults that have shown at the same time the speedometer goes out are: Powertrain fault, ABS, Forward Collision Warning, Parking Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Blind Spot Warning, Lane Keeping Assistance, Cross Traffic Warning. Also a random metallic spinning noise coming from under the truck. It has been in the dealer garage 5 times now.
Transmission encountered rough, jerky gear changes, along with delayed acceleration responses referred to as “hesitation" Rapid unexpected deceleration or inability to accelerate complete loss of motive power

High-speed highway travel this morning. Switched lanes and pressed accelerator; engine cut out. Seemed to be in no gear for 6-9 seconds before lurching into power again. Incident was very dangerous and forced a rapid slowing in fast lane affecting traffic behind me. This has happened 4 times in the past 8 months.
The recalls have been fixed!! Please update your records!!
10R80 transmission suddenly started showing symptoms of failure at 81,000 miles. Issues were slipping, jerking, and random gear selections. Safety was compromised when trying to merge (gas pedal pushed but truck didn't downshift initially, then drops to very low gear or from a dead stop would start in 10th gear and barely move), also when from a stop truck felt like it went into neutral when shifting into second almost causing rear end accidents and finally it would random leave shift into extremely low gear (1-2) when doing 20 causing a sudden breaking affect. Due to the safety concerns I did get the transmission replaced and symptoms have not returned. No warning lights appeared, AAMCO did the inspection as well as warranty company saying the transmission should be replaced.

Issues with the 10 speed automatic transmission and the adaptive learning. Rough, harsh, clunky shifting at times. Which could cause excessive ware or even failure I feel. Also, at around 70 mph the truck has this rattle or shaking . Not sure what it is .
The contact's business partner owns a 2021 Ford F-150. The contact stated that while his business partner was driving at an undisclosed speed, the vehicle lost motive power. The vehicle was towed to the dealer, where it was diagnosed with a fractured driveshaft. The dealer replaced the driveshaft. The manufacturer was made aware of the failure but informed the contact that the VIN was not included in the federal safety agency Campaign Number: 21V986000 (Power Train, Structure). The failure mileage was 80,230.
While driving my truck, I attempted a merge onto interstate 80, and completely lost power. I was accelerating to merge, and when the transmission shifted the truck lost all power. This is a dangerous situation and should be addressed. I cannot believe that nothing is being done about the issue, and Ford knows about this, as my local dealership is months out on transmission repairs.. It would sure be great if the agency responsible for forcing a recall would work for us..
Passenger side rear axle retainer bolt sheared off. My vehicle was manufactured 20 days after the existing recall. Repair was done under warranty but obviously should be included as part of the recall.
When moving the shift lever from Drive to Reverse, and physically feeling the two detents from Drive, through Neutral, and into Reverse, intermittently the shift lever will still indicate Neural and the vehicle will stay in Neutral even after two physical detents have been felt (i.e. the truck should indicate and be in Reverse after two physical detents). The truck and shift lever will stay in Neutral even after I remove my hand from the shift lever. The truck will only engage reverse after physically pressing the shift lever further forward within the physical Reverse detent area. There were no warnings on the dash and no trouble codes present within the system. The vehicle is available for inspection, and a video is available, however it is intermittently operating in this manner. When performing a 3-point turn on a roadway, this has led me to believe that my vehicle was engaged in Reverse, but it was in fact not, but in Neutral. This has introduced significant delay in what would otherwise be a safe maneuver and has put me and my occupants safety at risk. The local Ford dealership has updated the shift software, but it has continued to operate this same way intermittently. I have demonstrated this to the dealership service advisor and shown a video to the shop foreman, however the dealership is unwilling to replace the shifter because there is no trouble code. The vehicle has not been inspected by anyone other than the local Ford dealership.
On 11-28-2023 I took my truck in for an oil change and new tires. When the wheels were removed the passenger side rear axle bolt fell out. It had been sheared off and I don't know how long I had driven it like that. The last time the wheels were off was when I had an oil change and tire rotation at the same dealership in July 2023, they did not alert me to a problem at that time. The dealer said it was unsafe to drive and I should leave it there to await parts and service. My truck is a 2021 F-150 Ecoboost with the Max Tow Package. It has 54,520 miles on it. The dealer service department has not looked at it to determine if it is an eligible warranty repair or not at this time but it is scheduled to be inspected today. There were no warning lamps or messages given related to this problem at any time. My own research online indicates that hundreds of other 2021 and later F150 owners with the Max Tow Package have had the same problem of axle bolts breaking. No accidents or injuries have been reported that I know of but there has been lots of inconvenience because owners are told the trucks are unsafe to drive. The dealers are saying that the axles must be changed.
The bolt the holds the rear axle/hub on the 9.75 HD rear-end sheared off. This is an ongoing issue with their rear-end.
The contact owns a 2021 Ford F-150. The contact stated while stopped the vehicle was at a stop light, the vehicle displayed a message reading "Service Advanced Auto Track," requiring the vehicle to be shifted into park and restarted. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The engine kill switch warning light was illuminated. The vehicle was taken to three individual dealers, who were all unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 31,000.
It was discovered during rotating my Tires that the center bolt for my Rear axle had snapped off. In talking with the dealership this has been an issue with other ford products.
VEH: 2021 F150 FX4 SUPERCREW, 3.5L, MAX TRAILER TOW PKG COMPONENT FAILURE: Rear Passenger Axle Retainer Bolt (on Rear Axle Half-Shaft and Hub Assembly) On 11/03/2023, while having oil change at Simmons Rockwell Ford I was advised that they had located a snapped Axle Retaining bolt on rear passenger axle. I was advised that the axle to hub splines were also found to be damaged & loose. I was informed by service manager that he DID NOT RECOMMEND DRIVING VEHICLE DUE TO SAFETY CONCERNS. There is currently a Ford Customer Satisfaction Program #[XXX] in effect for some 2021-2022 F150 equipped with 9.75"HD Axle- 3/4 Float Axle. This Program replaces defective associated parts at no cost to owner w/no mileage limit. Production dates for F150's manufactured at the Dearborn plant included in this program are limited to May 1, 2021 thru September 30, 2021. My F150 was manufactured in 12/2020 and is not included in this program. My 2021 F150 manufactured in December 2020 has the exact same faulty axle & components as the F150's covered by this program. A check of internet shows multitudes of this same problem w/axle bolts breaking including vehicles outside of the cutoff dates of 22B34 set by Ford for this defect/safety issue. It's apparent F150's with the 9.75" HD axles (included with the Max Trailer Tow Package option) manufactured prior to May1, 2021 are also defective. I was advised by Simmons Rockwell Ford that my truck was the second f150 in two consecutive days to have the exact same problem w axle bolt breaking. Both of these F150 were manufactured outside of the dates included in CSP [XXX]. I was informed by Simmons Rockwell Ford that there are no current recalls for this safety issue. They further stated my F150 is out of warranty & this safety issue defect is not covered by warranty or the current Current Satisfaction Program [XXX]. This is a safety issue & warrants a recall for all models w/this axle including those manufactured before 05/01/2021. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF
