Battery Junction Box Underhood Fire (2020-2021 MY)
Vehicle catches fire under the hood while parked and off, or while driving; smoke from engine compartment; fire starts near passenger-side rear of engine bay.
2018-2026 Ford Expedition fire recall, seatbelt lock-up, and transmission defects? California lemon law may entitle you to a buyback. Free case review.
The 2018-2026 Ford Expedition is one of the largest SUVs on the market, marketed for real capacity and Ford's flagship engineering. Instead, owners across the current generation have logged engine fires, seatbelts that lock without warning, transmissions that clunk and slip, and fuel pumps that stall the vehicle on the freeway. NHTSA has issued eight separate recall campaigns on the current Expedition generation, plus multiple Technical Service Bulletins covering defects that Ford acknowledges but has not yet fixed for every affected owner. If your 2018-2026 Expedition has been back to the dealer two or more times for any of these complaints, whether fire risk, transmission, seatbelts, or engine noise, and the problem persists or recurred, California's Song-Beverly Consumer Warranty Act may entitle you to a manufacturer buyback, replacement vehicle, or cash settlement.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Vehicle catches fire under the hood while parked and off, or while driving; smoke from engine compartment; fire starts near passenger-side rear of engine bay.
Seatbelt suddenly cinches tight and locks; cannot be extended or retracted after locking; airbag/SRS warning light may illuminate before or after the event.
Harsh or clunky shifts (especially 3-4 or 7-8 upshifts); delayed engagement from Park or Neutral into Drive; RPM flare before gear catches; check engine light with transmission-related codes; transmission slipping or hesitation.
Ticking, tapping, or rattling noise from top front of engine for 2-5 seconds on cold start (after sitting ≥6 hours); intermittent failure to auto-restart during stop-start operation; check engine light with DTC P164C.
Rapid oil leak from engine; oil on garage floor or driveway after parking; oil smoke from engine bay; sudden engine stall while driving.
Engine stalls while driving with no warning; vehicle loses power and must be pulled over; engine hesitation or rough running before full stall.

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
Vehicle catches fire under the hood while parked and off, or while driving; smoke from engine compartment; fire starts near passenger-side rear of engine bay.
Catastrophic safety defect — vehicle fire while parked or off. Ford issued 'park outside' consumer alert; multiple structures damaged. Vehicles requiring repeated BJB service visits or persistent fire risk are strong lemon candidates.
Inspect BJB; replace if damaged. Remove a ground wire from BJB. On standard-duty radiator fan motor models, install auxiliary electrical box with wire jumper.
Seatbelt suddenly cinches tight and locks; cannot be extended or retracted after locking; airbag/SRS warning light may illuminate before or after the event.
Recall history spans 24V099 → 25V197 → 26V344, showing Ford repeatedly failed to fully remedy the defect. Owners who experienced inadvertent belt lock-up on vehicles that had been through prior recall repairs have a compelling repeat-repair argument under California lemon law.
Inspect production date codes on both front seatbelt retractors; replace retractors within suspect build date range; install HVAC drain tube elbow if not present.
Harsh or clunky shifts (especially 3-4 or 7-8 upshifts); delayed engagement from Park or Neutral into Drive; RPM flare before gear catches; check engine light with transmission-related codes; transmission slipping or hesitation.
Multiple failed repair attempts (software flash → valve body overhaul → CDF drum replacement) on the same complaint support repeat-repair lemon claims. Out-of-warranty CDF drum repair costs $3,500-$6,000, making buy-back highly favorable for owners.
2018-2021: PCM/TCM reprogram, adaptive learning drive cycle, and/or overhaul of main control valve body per TSB 23-2152. 2022: Replace CDF clutch cylinder with updated part JL3Z-7H351-B per TSB 24-2176; requires full transmission removal.
Ticking, tapping, or rattling noise from top front of engine for 2-5 seconds on cold start (after sitting ≥6 hours); intermittent failure to auto-restart during stop-start operation; check engine light with DTC P164C.
Engine noise complaint that requires complete VCT replacement on a vehicle under 3 years old qualifies as a substantial impairment. If dealer initially declined repair ('normal characteristic') before TSB was issued, that delay counts toward lemon repair attempts.
Replace all 4 VCT units (intake and exhaust cam phasers) per TSB 23-2143. Reprogram PCM. Reuse high-pressure fuel tube if not previously replaced.
Rapid oil leak from engine; oil on garage floor or driveway after parking; oil smoke from engine bay; sudden engine stall while driving.
Fire risk recall on a near-new vehicle. Owners who experienced oil-related stall or fire damage on a recently purchased Expedition have strong lemon and products-liability grounds.
Dealer inspects engine for misaligned cup plug; installs properly seated plug free of charge.
Engine stalls while driving with no warning; vehicle loses power and must be pulled over; engine hesitation or rough running before full stall.
Stall-while-driving recall with no remedy available is a strong basis for lemon claim: Ford has acknowledged the defect but cannot repair it yet, meaning the vehicle remains substantially impaired and owner cannot be required to wait indefinitely.
Remedy under development as of mid-2026; owners to be notified when available.

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 (commonly called the lemon law) requires a manufacturer or its authorized dealer to repair a covered defect within a reasonable number of attempts. If the manufacturer or dealer is unable to do so, you may be entitled to a full vehicle buyback (purchase price, taxes, fees, and finance charges, less a usage allowance) or a comparable replacement vehicle. Civil penalties up to two times your actual damages may apply when a manufacturer's failure to comply is willful.
Your Expedition is likely covered if: (1) the defect appeared within the manufacturer's new-vehicle warranty period; (2) Ford or its dealer made two or more attempts to repair a safety defect, or four or more attempts to repair any other defect; or (3) the vehicle was out of service for repairs for 30 or more cumulative days. Used Expedition purchases may also qualify if a manufacturer warranty was still active at the time of purchase. This overview is general information — it is not legal advice and does not guarantee any specific outcome. Whether your situation qualifies depends on the facts of your case.
“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.
A dealer writing 'unable to duplicate' or 'no fault found' on a repair order does not end your rights — in fact it can strengthen them under California lemon law. Here is what to do when a dealer cannot replicate your complaint:
Document before you go. Write down the exact conditions: outside temperature, how long the vehicle sat overnight, highway vs. city, load in the vehicle, AC setting. Engine fires and seatbelt lock-ups can occur with no advance warning; bring any photos, dashcam footage, or witness statements you have.
Ask for the recall check in writing. Before any other diagnosis, request that the service advisor pull your VIN against all open recalls. For an Expedition, that means 22V346/25V628 (fire), 26V344 (seatbelt), 24V851/25V198 (cup plug), and 25V455 (fuel pump). Ask them to note in the repair order whether each recall remedy has been completed on your VIN.
For intermittent transmission faults: request a PCM/TCM fault-code scan before any reset; ask the dealer to note any stored codes even if the check engine light is off. TSBs 23-2152 and 24-2176 require specific adaptive learning procedures and hardware inspection — ask whether the technician followed the TSB procedure.
For cam phaser rattle: the noise occurs during the first 2-5 seconds of a cold start after the vehicle has sat at least 6 hours. Bring the vehicle in as early as possible without warming it up, and ask the service writer to ride along on the start attempt. TSB 23-2143 governs this repair.
Keep every repair order. Each visit — even a 'no fault found' visit — is a documented repair attempt under the Song-Beverly Act. Two or more attempts on the same issue, or a vehicle out of service for 30 or more cumulative days, are the primary thresholds for a California lemon law claim.
The 2018-2026 Expedition has a recall record that is broader and more serious than most full-size SUVs in its class. The BJB fire defect is especially noteworthy: Ford acknowledged at least 25 fires including damage to nearby structures, issued a 'park outside' alert, and still needed a second recall campaign two years later to capture the 2020 model year. The seatbelt pretensioner defect required three successive recall campaigns before Ford issued a remedy that was intended to be complete. And the 2022 fuel pump recall carries the unusual distinction of having no remedy available as of mid-2026 — Ford has confirmed the defect but cannot yet fix it, which means 32,470 owners are driving a vehicle with an acknowledged safety defect and no repair date.
For transmission owners on 2018-2022 models, the escalating repair ladder — software flash, then valve body overhaul, then CDF drum replacement — is exactly the repeat-repair pattern lemon law was designed to address. If you have been back to the dealer two or more times for any single complaint on this vehicle, a case review costs you nothing.

Yes. NHTSA recalls 22V346 and 25V628 cover 2020 and 2021 model year Expeditions for a short circuit in the battery junction box that can cause an underhood fire while the vehicle is parked and turned off. Ford confirmed at least 25 fires, including damage to nearby structures, and issued a public consumer alert advising owners to park only outside and away from buildings until the repair is completed. If you own a 2020 or 2021 Expedition, check your VIN at the NHTSA recalls site or call your dealer to confirm whether the remedy has been performed on your specific vehicle.
If your front seatbelt suddenly cinches tight and then cannot extend or retract, your vehicle may have experienced an inadvertent pretensioner deployment — a defect that NHTSA confirmed in recall 26V344 affecting 2018-2022 Expeditions. The root cause is moisture entering through an HVAC drain seal that corrodes the pretensioner squib pin, triggering it without a crash. Ford has issued three successive recall campaigns for this same issue (24V099, 25V197, and now 26V344 covering 342,283 combined Expedition and Navigator units). If your seatbelt locked on a vehicle that had already been through an earlier recall repair, that is a compelling repeat-repair situation under California's lemon law.
Yes, 10R80 transmission harsh shifting and delayed engagement are confirmed defects on 2018-2022 Expeditions. Ford has issued Technical Service Bulletins 23-2152 (valve body overhaul for 2018-2021 models) and 24-2176 (CDF clutch cylinder replacement for 2022 models). The 2022-specific repair requires full transmission removal and costs $3,500-$6,000 when performed out of warranty. If your dealer has performed software flashes or valve body work and the harsh shifting persists, or if you have had two or more repair attempts for the same complaint, you may have grounds for a lemon law claim.
A ticking, tapping, or rattling sound from the top front of the engine lasting 2-5 seconds after the vehicle has sat overnight is a known symptom of worn variable camshaft timing (VCT) units — also called cam phasers — on 2018-2020 Expeditions with the 3.5L EcoBoost engine built on or before November 30, 2019. Ford addressed this in Technical Service Bulletin 23-2143, which calls for replacing all four VCT units and reprogramming the engine computer. Ford also ran Customer Satisfaction Program 21N03 to proactively cover this repair for some owners. If your dealer told you the noise was 'normal' before the TSB was issued but has since acknowledged the problem, the earlier visit still counts as a repair attempt under California's Song-Beverly Act.
Yes. NHTSA recall 25V455 (Ford campaign 25S75) covers 32,470 model year 2022 Expeditions for a low-pressure fuel pump defect that can cause the engine to stall while driving with no warning, creating a crash risk. As of mid-2026, Ford has confirmed the defect but has not yet released a repair remedy. Owners received an interim notification letter but no fix date has been announced. A vehicle with an acknowledged safety defect and no available repair remains substantially impaired under California law — meaning you cannot be required to wait indefinitely. If you experienced an unexpected stall and your 2022 Expedition is in this recall, consult a lemon law attorney.
You may qualify if your Expedition was purchased or leased in California and experienced a defect covered by the manufacturer's warranty that Ford or its dealer could not fix in a reasonable number of attempts. Common qualifying thresholds include: two or more repair attempts on a safety-related defect, four or more attempts on any other defect, or 30 or more cumulative days out of service. A buyback under Song-Beverly typically includes the full purchase price, taxes, finance charges, and registration fees, minus a usage allowance for miles driven before the first repair attempt. Attorney fees are paid by the manufacturer in qualifying cases — not by you. This is general information only; whether your situation qualifies depends on the specific facts.
