2021 Ford F-150 Hybrid

The contact owns a 2021 Ford F-150. The contact stated that while driving 85 MPH, the vehicle stalled, the interior electronics shut off, a red truck symbol flashed in the bottom right corner of the instrument panel, and a buzzing sound occurred inside the vehicle. The driver pulled over to the shoulder after crossing eight lanes of traffic. The vehicle was restarted after one hour. The manufacturer was notified of the failure by phone. The failure mileage was approximately 88,000.

Experiencing total stop of acceleration in two occasions: 1) when putting the car in reverse and pressing the accelerator and 2) when making a left or right turn after a yield or stop. And when I say loss of acceleration, I don’t mean hesitation, reduced power, or sluggish acceleration. I mean absolutely ZERO acceleration. I’ll press the accelerator and nothing happens. The engine stays basically at idle, and the truck will not accelerate for roughly 5-10 seconds, regardless of how much accelerator I’m giving it. Then suddenly power comes back and the truck drives normally again. This happens with normal operating temps while driving most of the day. It got to a point where it happened once every day. Very scary stuff when you're pulling out into traffic - major safety concerns with oncoming traffic.

My 2021 Ford F-150 PowerBoost, VIN [XXX], is included in Ford recall 25S75 / NHTSA recall 25V455. The vehicle has stalled more than five times and is experiencing the same dangerous condition described in the recall. The Ford dealer told me I can bring the truck in, and they will diagnose the problem and repair it if they can. However, I must pay all costs upfront and then request reimbursement after Ford releases the official recall remedy. I should not be required to pay out of pocket for the diagnosis and repair of a known safety defect covered by an active recall. There is also no clear timeline for when a remedy will become available or when I would be reimbursed. I cannot reasonably be expected to pay now and potentially wait years to recover my money. This vehicle repeatedly stalls and creates a serious crash risk. I am requesting that NHTSA investigate Ford’s delay and require Ford to provide an immediate, no-cost diagnosis and repair or provide safe alternative transportation until the recall remedy is available.

I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly shifts hard/lags on gears 3-5 and sometime higher gears 7-9 at higher speeds. I’ve also noticed a buzzing/metallic rattling coming near the engine from inside. There is also times i can tell i have no power when trying to speed up and the other day i almost thought i was going to get T-Boned. This occurred while on my daily traffic commute to work, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that NHTSA investigate the 10R80 CDF clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed.

2021 Ford F-150 PowerBoost Hybrid, VIN [XXX]. At 112,000 miles — just 1,000 miles outside of warranty — the vehicle experienced catastrophic failure of the hybrid battery system. Ford's own technician diagnosed a short in the high voltage battery system that caused damage to the hybrid electric drive unit. Repair estimate is $19,000. Ford declined goodwill warranty coverage despite the vehicle being only 1,000 miles outside warranty and the failure occurring on a known problematic system. This is a $72,000 vehicle purchased new in 2021 that has suffered a catastrophic drivetrain failure at only 3 years old. The high voltage battery short and hybrid drive unit failure represent a potential safety hazard to drivers and other motorists.

Several times, the vehicle has failed to accelerate or respond to accellerator pedal input for several seconds. It seems to happen when switching from electric to hybrid modes, and when shifting between lower gears simultaneously. Once the switch to hybrid occurs the engine will rev high with some acceleration even if the accelerator pedal is no longer being pressed. This acceleration has happened when I had my foot over the brake pedal in anticipation of pulling over to stop since the truck would not accelerate. There are no warning lights or messages that appear on the vehicle. It is dangerous because it seems to happen when trying to accelerate from a lower speed. If it happens when trying to change lanes in stop and go traffic or while pulling into traffic other cars would have to brake hard to avoid hitting our vehicle that has experienced stalled acceleration. It is also dangerous because once the transition happens there is brief uncommanded acceleration.

Vehicle Information 2021 Ford F-150 PowerBoost VIN: [XXX] Complaint Description While driving approximately 70 mph on a highway, my 2021 Ford F-150 PowerBoost suddenly displayed a “Stop Safely Now” message and immediately lost propulsion. The engine shut down without warning while I was in active traffic. After the shutdown, the vehicle automatically shifted into park and would not allow me to shift into neutral. This left me unable to move the vehicle out of a live traffic lane. I was forced to shut the vehicle off while still in a dangerous roadway position. This incident created a serious safety hazard, as I was traveling at highway speed and could have been rear-ended due to the sudden loss of power and inability to move the vehicle. This issue appears to match Ford Technical Service Bulletin (TSB) 23-2317, which describes “Stop Safely Now” warnings, no-start conditions, and gateway module (GWM) software faults. This indicates a known defect that can cause sudden loss of propulsion. A claim has already been opened with Ford Motor Company under case number [XXX], and the vehicle is currently at a Ford dealership for diagnosis. At this time, the issue has not been resolved. This failure occurred without warning and presents a significant risk to driver safety and others on the road.

The contact owns a 2021 Ford F-150. The contact stated while driving 45 MPH, the vehicle stalled. While at a stoplight, the accelerator pedal was depressed, but the vehicle failed to move or respond as needed. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the local dealer, who informed the contact that the failure might be battery-related. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that there was no warranty coverage on the vehicle. The failure mileage was approximately 140,000.

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)
