Used 2014 Ford F-150 Downshift-to-1st-Gear Recall (26V378): VIN History Check Before Buying

Key facts

• Campaign: NHTSA 26V378 (full ID 26V378000); Ford safety recall 26S45.
• Component: Power train, automatic transmission control module (PCM).
• Vehicles: 44,963 Ford F-150 trucks, model year 2014 only, built June 19, 2013 through December 23, 2014. Estimated defect rate: 100% of the population.
• Defect: Intermittent loss of the Output Shaft Speed (OSS) sensor signal to the Powertrain Control Module, from causes including contamination, a power short to ground, connector corrosion, connector pin swaging, and incorrect OSS sensor outputs.

What is the 2014 Ford F-150 downshift-into-first-gear recall (26V378)?

Recall 26V378, also tracked as Ford safety recall 26S45, covers 44,963 model-year-2014 Ford F-150 trucks built between June 19, 2013 and December 23, 2014. The defect is an intermittent loss of the Output Shaft Speed (OSS) sensor signal to the Powertrain Control Module. When that signal drops out, the transmission can abruptly and unexpectedly downshift into first gear without warning.

Ford lists several causes for the intermittent signal loss in this population: contamination, a power short to ground, connector corrosion, connector pin swaging, and incorrect outputs from the OSS sensor itself. NHTSA's consequence statement is direct: "Unexpectedly downshifting into first gear may result in a loss of vehicle control." The risk depends on vehicle speed at the moment of failure. The remedy is a free PCM software update (a reflash) performed by a Ford or Lincoln dealer.

Why is Ford recalling the same trucks it already tried to fix?

These 44,963 trucks were previously covered by Ford recall 24S37 (NHTSA 24V-444), whose owner letters mailed around July 1, 2024. That earlier recall addressed the exact same downshift-to-first-gear defect with a PCM software update. Ford later determined that this subset of trucks did not actually receive the 24S37 software remedy correctly, even though the repair was recorded and marked as completed.

In other words, 26V378 is effectively a re-do of a botched or incomplete prior recall fix. This matters enormously for a used buyer. A service record or recall lookup that says the earlier recall was "completed" cannot be trusted at face value on these trucks, because the entire reason for the new recall is that "completed" fixes were not installed properly the first time. The only reliable confirmation is a Ford or Lincoln dealer verifying, by VIN, that the latest 26S45 reflash is physically installed.

What years of F-150 are affected, and how is this different from the 1.4 million recall?

Recall 26V378 applies only to the 2014 model year, built June 19, 2013 through December 23, 2014. It does not cover 2015, 2016, or 2017 trucks. Trim, cab, and engine configuration are not differentiators; the population is defined by VIN, build window, and prior-recall repair records.

A separate, much larger recall has appeared in headlines and should not be confused with this one. The table below distinguishes the three related campaigns.

The 1.4 million-unit story is NHTSA 26V237, an April 2026 recall of 2015-2017 F-150s with the 6R80 transmission, where a lead-frame issue can cause a downshift from sixth gear to second, not into first. It is a different model-year range and a different defect from this 2014 recall.

Is it safe to drive a 2014 F-150 with this recall, and is the fix free?

The trucks in recall 26V378 are not under a do-not-drive order and are not under a park-outside order. That said, the defect can cause an abrupt, unintended downshift into first gear without warning, which NHTSA states may result in loss of vehicle control and increased crash risk. Ford has not published an explicit "safe to drive" statement in the coverage reviewed, so treat the open recall as a real safety item to resolve promptly.

The remedy is a no-cost PCM software update (reflash) performed by a Ford or Lincoln dealer, and Ford is offering reimbursement for prior related repairs. Owners are notified by mail beginning July 6, 2026, with notifications completed by July 10, 2026.

How do I check a used F-150 by VIN before buying?

Start with the free authoritative tools. NHTSA's recall lookup at nhtsa.gov/recalls becomes VIN-searchable for campaign 26V378 on July 6, 2026 and shows whether the recall is open on a specific truck. The Ford Owner Support recalls page and the Ford recall line at 1-866-436-7332 (reference 26S45) can confirm, by VIN, whether the latest reflash is actually installed at a dealer. Because this recall exists precisely because a prior "completed" repair was done wrong, dealer verification of the physical reflash is the single most important step here, not a paper record.

For the rest of the truck's history, a Zilocar VIN check is a useful complement alongside those tools. It screens for recall presence and count (the same presence signal as NHTSA's free lookup) and surfaces what a recall lookup cannot: accident and damage records, airbag deployment, odometer rollback, theft records, salvage and junk auction records, ownership count, and the truck's past sales-listing history. On a recall whose origin is a problem that a prior owner may have struggled with, that listing history (asking prices, mileage, days-on-market) can hint at whether a unit was offloaded as a problem.

What a VIN check can and can't tell you here

A Zilocar VIN check can confirm that a recall is present on a 2014 F-150 and can build a detailed picture of the truck's past, but it cannot tell you whether this specific recall was actually remedied. That gap is unusually important for 26V378, because the defect exists due to a prior "completed" repair that was installed incorrectly. Remedy confirmation, investigation status, and firmware detail must come from a Ford dealer and NHTSA.

Use a VIN check for the history and recall-presence screen; then confirm the remedy by VIN with a Ford or Lincoln dealer or the Ford recall line, and at NHTSA once 26V378 is searchable.

Run a VIN check before you sign

Before buying any used 2014 F-150, a Zilocar VIN check screens for recall presence and surfaces accident and airbag-deployment records, salvage and junk-auction records, odometer rollback, theft records, ownership history, past sales-listing history, specs, NHTSA and IIHS ratings, and a market valuation. It does not confirm whether a recall was remedied, track NHTSA investigations, show firmware status, or classify the legal title brand, so pair it with a dealer's by-VIN reflash confirmation.
