Ford is recalling 148,663 model-year 2024–2026 Mustang vehicles because engine-compartment wiring-harness ground connections may fracture. The federal campaign number is 26V547, and Ford identifies the action as 26C40.
A fractured connection can cause a loss of drive power or disable the headlights, windshield-washer system, air conditioning or engine-cooling fan. NHTSA says loss of power or reduced visibility can increase crash risk. The vehicles also fail federal requirements for lighting and windshield washing.
What the record says
Ford dealers will replace the engine-compartment wiring-harness ground terminals at no charge. Interim owner letters were expected to begin August 31, but the final remedy is not anticipated until March 2027. VINs became searchable in NHTSA’s system on August 28, so owners do not need to wait for a letter to check.
What dealers and customers should know
What this means for owners: enter the VIN in Ford’s or NHTSA’s recall lookup and save the campaign number. Confirm that Ford and your dealer have current contact information, then ask to be notified as soon as parts and appointments are available. NHTSA does not label this campaign Do Not Drive or Park Outside, so follow Ford’s VIN-specific instructions rather than assuming every Mustang must be parked.
If the vehicle loses power or exterior lighting while moving, turn on the hazard lights if they still work, steer to a safe location without making abrupt maneuvers and request roadside help. Do not attempt to repair or add ground connections yourself; the recall remedy is free.
What this means for shoppers: run the VIN before buying or accepting delivery of a 2024–2026 Mustang. Ask for written recall status and, once the remedy launches, documentation showing campaign 26C40 was completed. A vehicle’s normal operation during a test drive does not prove the ground terminals are outside the recall.
Why it matters
the long wait for the final repair makes early VIN checking especially important. The useful action today is to identify an affected car and get into the manufacturer’s notification process, not to guess from trim level or visible condition.
