Ford Mustang recall 26V547 (Ford 26C40) covers about 148,663 2024-2026 Mustangs built from September 7, 2022 to June 9, 2026. Ground eyelet terminals in the engine-compartment wiring harness can fracture, which can cut drive power or disable a headlamp, the windshield-washer pump, air conditioning or the cooling fan. The fix is a free dealer replacement of four ground terminals.

What causes the problem
A ground eyelet is the ring terminal that bolts an electrical ground to the vehicle. Ford says heat-shrink material added to the harness can interfere with the eyelet’s bolt-clearance area, bending the terminal and shortening its fatigue life under vibration. If it fractures, the circuit using that ground can fail.
- Loss of drive power
- Right or left headlamp failure
- Windshield-washer pump failure
- Air conditioning loss
- Engine cooling fan failure
Ford says some drivers may see a Check Engine light, an instrument-cluster message or hear a chime, depending on which ground fails. A warning light alone does not prove this defect, so have a dealer diagnose it.
Safety: if your Mustang loses drive power or headlights while driving, move out of traffic as safely as possible and stop. Arrange dealer service or roadside assistance, and follow any instructions in your recall notice.
Wipers vs washer pump: a separate recall
Recall 26V547 concerns the washer pump, not the wiper motor. A separate Ford campaign, NHTSA 26V418, covers a cold-weather wiper-motor issue on certain Mustangs. They involve different parts, populations and repairs.
How Ford will fix it
Dealers replace four engine-compartment wiring-harness ground terminals with revised standoff eyelet pigtails at no charge. The recall does not call for replacing the whole harness. The filing scheduled interim owner letters for August 31 to September 4, 2026, and remedy notification planned for March 31, 2027, so the final repair may not be available for every VIN yet. Schedules can change, so confirm with your dealer.
How to check your Mustang
- Find the 17-character VIN on the lower windshield, registration or insurance card.
- Search it in the NHTSA recall lookup. It shows unrepaired recalls and may not show completed ones.
- If 26V547 or 26C40 is open, ask a Ford dealer whether the remedy is available for your VIN.
- Keep the recall result and repair paperwork.
If you already paid to fix the same ground-terminal problem, keep the invoice and ask Ford or the dealer about reimbursement. Ford’s filing says it will use its general reimbursement plan, but eligibility depends on the repair, timing and documents.
