Parking brake fires on its own, axle bolts fracture, engine stalls with no fix. Repeated issues? Your 2021-2025 F-150 may qualify for a California buyback.
Ford's 14th-generation F-150 (2021-2026, P702 platform) launched with promises of an all-new aluminum body, advanced SYNC 4 technology, and the most capable towing setup in the lineup. What came with it, for tens of thousands of owners, was a string of serious, safety-critical defects that have produced more than ten federal recall campaigns in just five model years. The two most alarming: an electric parking brake that activates on its own while you are driving, and rear axle hub bolts that fracture under load, potentially allowing the truck to roll away when parked or lose rear drive power without warning. The parking brake wiring problem (Recall 23V509, July 2023) affected 870,701 trucks, nearly every 2021-2023 F-150 with a single exhaust. NHTSA records show 299 documented unintended parking brake activations, 19 of them while the truck was moving. The rear axle hub bolt fracture spread across two recall campaigns (23V896 and 25V512) covering a combined ~216,000 trucks from model years 2021 through 2025. Both recalls remain open as of mid-2026. Beyond those two standout issues, 14th-gen F-150 owners have faced engine stalls from a defective low-pressure fuel pump (850,000-unit open recall, no remedy yet as of mid-2025), rearview cameras that freeze or go black while reversing, 10-speed transmissions that drop to Neutral mid-drive, and, for 2021 model year trucks with the 2.7L EcoBoost, intake valves that fracture and destroy the engine. If your 2021-2026 F-150 has been back to the dealer for any of these problems more than once, or has spent a significant stretch out of service, California's lemon law may require Ford to buy your truck back.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Sudden loss of engine power while driving; engine misfires or runs rough; check engine light illuminates; engine may stall; metallic debris in engine.
Parking brake activates suddenly while driving; rear wheels lock up; vehicle lurches to a stop; brake warning light may illuminate; loss of vehicle control.
Clicking or grinding from rear axle; vehicle rolls in Park without parking brake; sudden loss of rear drive power; stripped hub splines (may not present until failure is advanced).
Wiper blades move erratically or stop moving; wipers fail to park correctly; wiper arm detaches from vehicle; reduced or no visibility in rain.
Harsh or banging gear shifts; delayed engagement from stop; transmission slips or drops to Neutral unexpectedly while driving; check engine light; vehicle hesitates or lurches during acceleration.
Backup camera image freezes, turns black, shows a still frame, or does not appear when shifting into Reverse; SYNC 4 infotainment screen may reboot while backing; delayed camera activation.

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
Parking brake activates suddenly while driving; rear wheels lock up; vehicle lurches to a stop; brake warning light may illuminate; loss of vehicle control.
Safety recall with 870,701 units; 299 documented EPB activations while driving. High repeat-repair potential if harness chafe recurs; supports substantial-impairment and safety-risk prongs.
Inspect rear axle wiring harness; replace harness if protective tape is damaged; install tie strap and tape wrap to prevent recurrence.
Clicking or grinding from rear axle; vehicle rolls in Park without parking brake; sudden loss of rear drive power; stripped hub splines (may not present until failure is advanced).
Two recall campaigns (23V896 + 25V512) covering 2021-2025 MY; rollaway risk is a per-se safety impairment. Repeat recall on same component strengthens lemon-law argument.
Replace left and right rear axle shaft assemblies with revised design incorporating improved spline geometry and fasteners.
Wiper blades move erratically or stop moving; wipers fail to park correctly; wiper arm detaches from vehicle; reduced or no visibility in rain.
Safety recall (22V250 / Ford 22S26); wiper failure in rain is a per-se visibility and safety impairment. Affecting 2021 MY specifically; earlier 14th-gen buyers most exposed.
Replace both wiper arms; vehicles built after June 7, 2021 inspected and replaced if necessary.
Harsh or banging gear shifts; delayed engagement from stop; transmission slips or drops to Neutral unexpectedly while driving; check engine light; vehicle hesitates or lurches during acceleration.
Recall 22V188 (neutral drop) + multiple TSBs covering same generation. Persistent shift complaints across 2021-2023 MY suggest systemic condition; repeat repair attempts strengthen substantial-impairment argument.
PCM/TCM software update (recall remedy for neutral drop); valve body overhaul and adaptive learning drive cycle for harsh-shift variants.
Sudden loss of engine power while driving; engine misfires or runs rough; check engine light illuminates; engine may stall; metallic debris in engine.
Engine replacement is the most severe possible repair; even a single confirmed intake-valve failure requiring engine replacement almost certainly satisfies the substantial-impairment and repair-attempts thresholds under California lemon law.
Dealer performs engine cycle test; replace engine assembly if intake valve anomalies detected. No charge to owner.
Backup camera image freezes, turns black, shows a still frame, or does not appear when shifting into Reverse; SYNC 4 infotainment screen may reboot while backing; delayed camera activation.
NHTSA 25V315 covers 527,371 F-150 units (2021-2024 MY); rearview camera is a mandatory FMVSS safety device — its failure is a per-se safety defect. If OTA fix fails or issue recurs, supports repeat-repair claim.
Free APIM software update; delivered over-the-air or at dealership.
Engine stalls or loses power unexpectedly; poor engine performance; check engine light; difficulty restarting after stall; symptoms more likely in low-fuel or hot weather conditions.
Active open recall with no remedy yet (as of mid-2025); engine stall at highway speed is a catastrophic safety event. Owners awaiting remedy are particularly vulnerable; non-conformity is current and ongoing.
Remedy under development as of July 2025; interim owner notification issued. Final fix expected to involve fuel pump/module replacement.
Vibration or scraping noise from under vehicle; sudden loss of power; vehicle rolls freely when parked without parking brake; driveshaft may contact ground.
Two recall campaigns covering same driveshaft defect (21V986 + 22V623); 27 confirmed driveshaft fractures before first recall. Rollaway risk from driveshaft separation supports safety-defect claim.
Inspect and securely fasten underbody insulators; inspect driveshaft for damage and repair or replace as needed.
open
Follow-on to 23V896; wheel-end hub bolt may loosen or break; continued driving causes hub spline wear; stripped splines may lead to rollaway when parked or loss of motive power while moving.
open
GEN 4.6 low-pressure fuel pump manufactured outside internal clearance specification; increased internal friction combined with low fuel or high ambient temperature can cause pump failure and engine stall.
open
Software defect in APIM (SYNC 4 versions 1.7–1.9) causes rearview camera image to delay, freeze, or fail to display when vehicle is shifted into Reverse.
closed
Engine intake valves manufactured outside designed hardness specification; over-hardened (brittle) valves may fracture during normal operation, causing catastrophic internal engine damage and sudden loss of drive power.
open
Hub bolt may fracture due to fatigue, allowing micro-movement and spline wear between hub and axle shaft; corrosion accelerates fretting; stripped splines can no longer hold vehicle in Park or transmit drive force.
open
Rear axle wiring harness contacts the rear axle housing; repeated chafing wears through abrasion tape and wire insulation, exposing copper conductors that ground on the axle housing, causing unintended electric parking brake activation.
closed
Expands 21V986; additional vehicles with erroneously installed underbody insulators (XL/XLT 301A and below; Tremor 400A) also affected; same contact-and-fracture mechanism.
closed
Supplier used incorrect tooth height in wiper arm spline; the higher-torque wiper motor strips the spline, causing wiper arm to lose engagement with the motor and fail to sweep or park correctly.
closed
PCM software error causes the transmission to erroneously detect low transmission fluid pressure and shift to Neutral, resulting in sudden unexpected loss of drive propulsion.
closed
Underbody heat/noise insulation panels installed in error on 4x4 crew cab models; panels can loosen, sag, and contact the aluminum driveshaft, scoring and eventually fracturing it.
Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act gives you the right to a repurchase, replacement, or cash settlement when Ford cannot fix a defect within a reasonable number of repair attempts or within a reasonable time. For safety-related defects — like a parking brake that fires while you are driving or a truck that can roll away in Park — California law presumes two repair attempts may be sufficient to establish your rights. For other substantial defects, four repair attempts, or 30 or more cumulative days out of service during your warranty period, can trigger the same presumption. If your F-150 qualifies, you may be entitled to: a full repurchase of what you paid (minus a mileage offset calculated from when the problem first appeared), a comparable replacement vehicle, or a negotiated cash settlement. Ford pays your attorney fees if you win — meaning most California lemon law cases cost the owner nothing up front. The parking brake recall's continued-open status, the two-campaign rear axle hub bolt story, the fuel pump recall with no remedy available, and persistent transmission problems all represent the type of nonconformities California lemon law was designed to address. The above is general information and is not legal advice; your rights depend on your specific service history and dates.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
Ford dealers routinely close repair orders as 'unable to duplicate' (UTD) or 'no trouble found' (NTF) for intermittent safety problems like the electric parking brake activation or a transmission that drops to Neutral and re-engages before you reach the dealer. That does not end your rights — it just means you need to build a better paper trail. Here is how: 1. Document every event immediately. For the electric parking brake, record the exact date, time, speed, and what you felt. For a stall or Neutral drop, note the engine conditions (hot or cold, fuel level, road speed). Photograph any warning lights before clearing. 2. Request all stored and pending Diagnostic Trouble Codes in writing. The electric parking brake wiring fault (chafe causing a ground fault on the EPB circuit) and the transmission's false low-pressure event each leave electronic footprints in the module memory even after the codes clear themselves. 3. Ask the dealer to check these specific open recalls before closing the RO: Recall 23S35 / 23V509 (electric parking brake harness), Recall 23S65 / 23V896 and Recall 25S82 / 25V512 (rear axle hub bolt), Recall 25S75 / 25V455 (fuel pump), and Recall 25S49 / 25V315 (SYNC 4 rearview camera). If your VIN is listed and the remedy has not been applied, the dealer is legally required to perform the recall work. 4. For the fuel pump recall (25V455): as of mid-2025 there is no remedy yet. If you stall and the dealer sends you home with 'nothing to do today,' document that in writing. An open recall with no available remedy and a recurring stall symptom is a strong lemon fact pattern. 5. Save every repair order, even UTD ones. California counts them all.
The 14th-generation F-150 launched with more open safety recalls per model year than almost any F-150 in memory. The electric parking brake activating while you drive, a rear axle that can strand you or roll your truck in a parking lot, an engine that stalls with no fix available — these are not minor inconveniences. If your 2021–2025 F-150 has made repeated dealer trips for any of these issues, the service records you already have may be enough to open a California lemon law case. Pull together every repair order and get a free case review before your warranty window closes.
— The Margarian Law team
Has your 2021–2025 F-150 experienced a parking brake that engages on its own, a stall on the highway, a camera that goes dark when you need it most, or a transmission that drops to Neutral without warning? If you have made two or more dealer trips for any of these documented defects — or if an open recall has no remedy available and your truck keeps failing — your repair records may already support a buyback under California law. A free case review costs you nothing and tells you exactly where you stand.
Likely yes, if your truck has a single exhaust system. NHTSA recall 23V509 (Ford recall 23S35, issued July 2023) covers 870,701 F-150s from model years 2021 through 2023 equipped with a single exhaust. The defect: the rear axle wiring harness repeatedly contacts the rear axle housing; abrasion wears through the protective tape and wire insulation; exposed copper wires ground on the axle housing and cause the electric parking brake to activate without driver input. Ford's warranty data recorded 918 field reports and 299 documented unintended EPB activations — 19 while the truck was in motion — before the recall was issued. The recall remains open as of mid-2026; check your VIN at nhtsa.gov. The remedy involves inspecting and, if damaged, replacing the rear axle wiring harness and adding a protective strap and tape wrap to prevent recurrence.
It is serious. Ford issued two separate recall campaigns for the same rear axle hub bolt defect. Recall 23V896 (Ford 23S65, December 2023) covered 112,965 trucks from model years 2021 through 2023 with the Trailer Tow Max Duty package and a 9.75-inch heavy-duty 3/4-float rear axle. The hub bolt can fracture due to fatigue; the fractured bolt allows micro-movement between the hub splines and the axle shaft splines; corrosion accelerates the wear; and eventually the splines strip completely. A truck with stripped splines can roll in Park without the parking brake applied, or lose rear-wheel drive power while moving. Recall 25V512 (Ford 25S82, August 2025) then expanded coverage to approximately 103,000 additional trucks from model years 2023 through 2025. Both recalls remain open. The remedy — replacing both rear axle shaft assemblies with a revised design — is available under 25V512.
Yes. NHTSA recall 25V455 (Ford recall 25S75, July 2025) covers approximately 850,000 vehicles — including 2021 and 2022 F-150s built between July 1, 2021 and July 31, 2022 — for a low-pressure fuel pump defect. The pump was manufactured outside the designed internal clearance specification; reduced internal clearances increase friction, and the pump can fail under low-fuel or high-ambient-temperature conditions, cutting fuel supply and stalling the engine while the truck is moving. Ford projects that approximately 10 percent of recalled vehicles will experience this failure. As of July 2025, no remedy had been released; Ford issued interim owner notifications and promised a second notice when a fix is available. If your truck has stalled and the dealer says there is nothing they can do yet because no remedy exists, document that response in writing. An active recall with no remedy and a recurring stall is a strong lemon law fact pattern in California.
Yes. NHTSA recall 25V315 (Ford recall 25S49, May 2025) covers 527,371 F-150 units from model years 2021 through 2024 equipped with the SYNC 4 infotainment system running APIM software versions 1.7 through 1.9. A software defect in the Accessory Protocol Interface Module (APIM) can cause the rearview camera image to delay, freeze on a still frame, or fail to display at all when the truck is in Reverse. Because federal safety standards (FMVSS 111) require a functioning rearview camera, NHTSA treats this as a safety recall. The remedy is a free APIM software update, available over the air or at your dealer. If your dealer performed the OTA update and the camera still freezes, or if the issue returns, that second visit is an additional repair attempt for the same defect — relevant to a potential lemon law claim.
It may, depending on your specific repair history. California's Song-Beverly Consumer Warranty Act presumes a vehicle is a lemon if the manufacturer has made two or more repair attempts for a safety-related defect, or four or more attempts for any substantial defect, or if the vehicle has been out of service for 30 or more cumulative days during the warranty period. For the 14th-gen F-150, there are multiple pathways. The electric parking brake recall (23V509) is a safety defect — two repair attempts for the same chafing symptom could trigger the presumption. If you are waiting on the fuel pump recall (25V455) with no remedy available and the truck keeps stalling, time spent waiting and trips made for that defect count. The rear axle hub bolt defect spanning two recall campaigns is another strong angle if your truck was brought in under both 23V896 and 25V512. The analysis depends on your actual repair orders, mileage at first complaint, and dates of service visits. A California lemon law attorney can review your records at no charge; Ford pays the attorney's fee if you prevail.
Yes, it is dangerous. An electric parking brake that activates while the truck is moving can cause sudden rear-wheel lockup, loss of directional control, and a crash. NHTSA recall 23V509 documents exactly this hazard across 870,701 trucks. Nineteen owners in Ford's own warranty database reported unintended activation while driving before the recall was issued. If this happened to you: first, bring your truck to the dealer immediately and ask them to apply Recall 23S35. The remedy is inspecting the rear axle wiring harness and replacing it if damaged, plus adding protective hardware to prevent re-chafing. Second, document the event in detail — date, speed, road conditions, what you felt, and any warning lights. If the parking brake activates again after the recall repair, that is a second repair attempt for the same safety defect, which under California lemon law may be enough to trigger your right to a buyback or replacement.
