The National Highway Traffic Safety Administration has opened an investigation into 1,270,970 Ford F-150 pickup trucks over a potential transmission defect. The probe covers 2015, 2016, and 2017 model years equipped with the 6R80 six-speed automatic transmission. The issue may cause unexpected downshifts, raising safety concerns for drivers.
Ford F-150: Transmission Issue & Sensor Signal Loss
According to investigation documents, the problem stems from signal loss in the Output Shaft Speed sensor. Degraded electrical connections in the transmission lead frame can interrupt signals to the Transmission Range Sensor.
When this occurs, the gearbox may shift unexpectedly. The transmission could downshift multiple gears, shift into neutral, or upshift without driver input, depending on operating conditions.
Ford F-150: Risk Of Wheel Lockup & Driving Instability
NHTSA states that unexpected downshifts at speeds between 35 and 64 MP/H may cause the transmission to shift into second gear. In certain cases, this abrupt change can temporarily lock the rear wheels.
More than 300 owner complaints have been documented. Over 40 percent of those reports mention at least one rear wheel lockup event linked to sudden downshifting.
Ford F-150: Additional Safety Concerns
Preliminary testing by the Vehicle Research Test Center highlights another risk. If the Transmission Range Sensor signal is lost while reversing uphill, the truck may shift into neutral unexpectedly.
This could cause the vehicle to roll forward without warning. Such behavior increases the risk of accidents, especially in tight parking areas or on inclined roads.
Difference From Previous Recalls
Ford has clarified that this investigation differs from earlier Output Shaft Speed sensor recalls affecting 2011 to 2014 models. The current issue involves different components and electrical behavior within the 6R80 transmission system.
NHTSA’s Office of Defects Investigation will determine whether a formal recall is necessary after further evaluation and testing.
Middle East Market Relevance
The Ford F-150 has a strong presence in parts of the Middle East, particularly among buyers who import US-spec models. Owners of 2015 to 2017 units in the UAE or Saudi Arabia should verify VIN status with authorized dealers.
Given the region’s high-speed highways and desert terrain use, sudden transmission downshifts could pose serious safety risks.
Prices In The Middle East
Used 2015 to 2017 Ford F-150 models in the UAE currently range between AED 85,000 and AED 140,000, depending on trim level, mileage, and engine configuration.
Popular variants such as EcoBoost V6 models command higher resale values. Owners of potentially affected trucks should monitor official updates regarding recall decisions.
Conclusion
The investigation into nearly 1.3 million Ford F-150 trucks highlights serious concerns involving the 6R80 automatic transmission. Signal loss in key sensors may cause sudden downshifts, rear wheel lockup, or unexpected shifts into neutral.
While no official recall has been issued yet, NHTSA continues to review complaints and conduct testing. Owners of affected model years should stay alert for updates and ensure their vehicles are inspected if symptoms arise.
