What was reported

Source: manufacturer filing, 49 CFR Part 573
Problem Ford Motor Company (Ford) is recalling certain 2024-2026 Mustang vehicles. The engine compartment wiring harness ground connections may fracture and result in a loss of drive power, or a loss of function in the windshield washing system, headlights, air conditioning, or engine cooling fan. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 108, "Lamps, Reflective Devices, and Associated Equipment," and 104, "Windshield Wiping and Washing Systems." Risk A loss of driver power increases the risk of a crash. In addition, a loss of headlight function or windshield washing system function can reduce visibility, increasing the risk of a crash. Fix Dealers will replace the engine compartment wiring harness ground terminals, free of charge. Interim letters, notifying owners of the safety risk, were mailed September 5, 2026. Additional letters will be sent once the remedy is available, anticipated in March 2027. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26C40. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on August 28, 2026.

Reported to NHTSA Aug 25, 2026 by Ford Motor Company.

What that means, in plain English

Source: WhichTrim's reading of the filing above — not NHTSA's wording

Fractured ground connections can cause loss of drive power in traffic and loss of headlights, both of which directly enable a crash, placing this firmly in the high category despite no stop-drive order issued.

Written for us by a language model from the manufacturer's filed text, which is quoted in full above. Where the two differ, the filing is the record and this is only our summary of it.

The fix, from the dealer bulletin

Source: NHTSA remedy instructions and dealer notice
Stop-sale Not stated in the dealer documents
Remedy Available: including repair instructions have been provided to dealers

The remedy, in the manufacturer’s words: availability including repair instructions have been provided to dealers.

Read from NHTSA’s copy of the manufacturer’s dealer documents (manufacturer campaign 26C40). The procedure itself is in the bulletin; a franchised dealer has the current copy on the manufacturer’s portal, and that copy governs. Working a lot or a fleet? Recall Watch carries this line on every VIN it checks: remedy status, hours, stop-sale.

Which vehicles are covered

Vehicles built Sep 7, 2022 to Jun 9, 2026 — a VIN outside that window is not part of this campaign even if the year, make and model match.

Those are the model years inside WhichTrim's range, 2016 onward. The campaign may cover others outside it, and the only thing that settles whether one specific vehicle is included is its VIN.

Check one specific vehicle

A recall applies to a build range, so year, make and model cannot settle it. Type the VIN and the WhichTrim recall report checks this campaign’s build window and engine against it.

Common questions

Source: NHTSA, 49 CFR Part 573

Is 26C40 the same recall as 26V547000?

Yes. 26C40 is the number Ford Motor Company uses for this campaign in its own paperwork and in the letter it sends owners. 26V547000 is the number NHTSA files it under. One recall, two references — dealers and service departments generally quote the manufacturer's.

Does this recall repair cost anything?

No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.

How do I know whether my vehicle is included?

By VIN, not by model year. This campaign covers vehicles built Sep 7, 2022 to Jun 9, 2026. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.

What if the repair is not available yet?

It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. This campaign was filed without a repair available — Ford Motor Company says so in the text above, and expected one by March 2027.

What did the manufacturer say was wrong?

The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.

Who started this recall?

NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
