Ford is recalling 552,188 examples of the 2014 F-150 to deal with a transmission defect that may result in random downshifts into first gear at any car pace. A sudden downshift to first gear at excessive pace can result in a lack of management and/or probably immobilizing the car. Ford says a misbehaving driveline sensor is the wrongdoer.
“Some automobiles might expertise an intermittent lack of the transmission Output Shaft Pace (OSS) sensor sign to the Powertrain Management Module (PCM), probably leading to a brief, unintended downshift into first gear,” Ford’s recall report mentioned. “Relying on the car pace on the time of an intermittent OSS failure, an abrupt transmission downshift to first gear might happen. A downshift to first gear with out warning might end in a lack of car management, rising the danger of a crash.”
Complicating the difficulty is the truth that Ford has recognized a number of causes for OSS sign points (contamination, energy brief to floor, connector corrosion, connector pin swaging, and incorrect outputs from the OSS sensor), so there is not any single approach to instantly treatment the issue. As a substitute, Ford is updating the shift logic to incorporate a “plausibility test” that can ensure that the pace being indicated by the OSS really is smart earlier than commanding an computerized shift into first gear. If this all rings a bell, earlier mannequin years of the F-150 have been topic to a recall for a similar problem.
Ford’s report didn’t point out that any vehicles suffered from irreparable driveline harm on account of the downshift, nevertheless it famous a number of cases the place the difficulty led to the rear wheels of the truck locking up or the driving force in any other case shedding management.
House owners ought to look ahead to a notification from Ford earlier than taking their F-150s in for service. House owners ought to start to obtain mailers from Ford a while in early July. Those that had associated repairs carried out beforehand exterior of guarantee are eligible for reimbursement.
