2026 Ford MustangFordFord is recalling nearly 149,000 Mustangs in the United States because a problem with the engine-compartment wiring harness can cause the cars to lose drive power and disable several important systems, including the headlights and windshield washers.The recall covers 148,663 model-year 2024 through 2026 Ford Mustangs, says t he National Highway Traffic Safety Administration. Ford's internal recall number is 26C40 - NHTSA lists the campaign as 26V547.The issue is that ground connections in the engine-compartment wiring harness that can fracture. If that happens, the Mustang may lose drive power. The same fault can also disable the headlights, windshield-washer system, air conditioning or engine cooling fan.AdvertisementAdvertisementThat combination gives the recall more seriousness than a nuisance electrical problem. A sudden loss of propulsion can increase the risk of a crash. Losing headlights or windshield washing capability can sharply reduce visibility, particularly at night or in lousy weather.The good news? Ford says it is not aware of any crashes or injuries associated with the condition.The recall includes new MustangsThe affected Mustangs were built between Sept. 7, 2022, and June 9, 2026, meaning the recall reaches across much of the current-generation Mustang's production run. The seventh-generation Mustang arrived for the 2024 model year and includes everything from the four-cylinder EcoBoost to V8-powered GT and Dark Horse models. The recall notice does not say every Mustang built during that span is affected, so owners will need to check their individual vehicle identification number.The repair itself is straightforward - Ford dealers will replace the engine-compartment wiring-harness ground terminals at no charge to owners.AdvertisementAdvertisementThe timing, however, isn't convenient.Ford began sending interim notification letters to owners on Aug. 31, warning them about the safety risk, but the company does not expect the final remedy to become available until around March 2027. A second round of letters is expected once replacement parts or the repair procedure are ready, says the company.AUSTIN, TEXAS - JUNE 24: Ford Mustang Mach-E vehicles are seen for sale on a dealership lot on June 24, 2025 in Austin, Texas.

In June, the automaker recalled more than 91,000 U.S. vehicles because daytime running lamps may fail to dim properly, potentially creating glare for other drivers as well as bad feelings, and people flashing their own high beams in retaliation, creating a hazard.AdvertisementAdvertisementMustang owners have also dealt with a separate 2026 recall involving windshield wiper and washer-system operation in cold temperatures.Owners can check for open recalls by entering their VIN at NHTSA's recall website or through Ford's recall lookup system.It's freeRecall repairs are performed free of charge.For Mustang owners, the important number here is 26C40. If it shows up against the car's VIN, the next step is to watch for Ford's notification and, once the remedy becomes available, schedule the repair with a dealer.Ride safe JMThis article was originally published on Forbes.com
