“In affected vehicles, the engine compartment wiring harness ground eyelet terminals may experience fatigue fracture. Depending on which ground eyelet fractures, this condition may result in a loss of motive power, loss of right and/or left headlamps, loss of windshield washer fluid pump function, loss of air conditioning, and/or an inoperable engine cooling fan,” Ford said in the mandatory safety defect recall filing made public by the National Highway Traffic Safety Administration (NHTSA) this morning.

The revised service standoff eyelet pigtails have redesigned stepped-neck terminal geometry. This modified geometry eliminates clamp-up interference and out-of-plane bending stress under vehicle vibration.
