Federal Safety Agency Expands Probe Into Popular Ford Pickup Trucks
A federal investigation has been expanded to encompass nearly 1.3 million of America's most popular pickup trucks, focusing on a transmission defect that drivers report can trigger sudden and alarming gear changes. The National Highway Traffic Safety Administration (NHTSA) has broadened a probe initiated last year to include Ford F-150 models from the 2015, 2016, and 2017 model years.
Drivers Report Unexpected Downshifts and Wheel Locking
Numerous drivers have informed regulators that their trucks can unexpectedly downshift "without warning or driver input" while traveling at speed. In several documented cases, motorists reported the rear wheels briefly locking up, a dangerous scenario that can lead to loss of vehicle control, particularly on highways or slippery road surfaces. The NHTSA's update on January 30 noted that, among the hundreds of reported incidents, no injuries or fatalities have been recorded thus far.
Ford has communicated to regulators that this current transmission issue is distinct from a previous downshifting problem that prompted the recall of model years 2011 through 2014. For the newer trucks under investigation, the automaker indicates the likely cause is the degradation of an electrical connection to the transmission range sensor. This deterioration can cause the truck's onboard computer to receive incorrect signals regarding the appropriate gear for the vehicle.
Potential for Serious Safety Incidents
The worst-case scenario involves a downshift to second gear while the vehicle is traveling at high speed, which could result in the rear wheels locking up. Federal investigators have identified another potential hazard: if a signal loss to the sensor occurs while the affected vehicle is reversing up an incline, "the vehicle may shift into neutral causing the vehicle to change directions and roll forward."
This investigation represents the latest safety concern to emerge surrounding America's bestselling truck line. In a separate action last September, Ford recalled 115,539 F-150 trucks due to a defect that could cause components to detach within the steering system. The company warned this problem "may result in a loss of steering, which could increase the risk of a crash," affecting model year 2020 through 2021 F-250, F-350, and F-450 trucks.
Ford's Broader Recall Challenges
Ford is confronting persistent issues with vehicle recalls, having earned the dubious distinction of issuing the most recalls in three of the past four years. In 2025, the automotive giant broke the record for the number of recalls in a single year—achieving this milestone by the halfway point. Ford issued a total of 152 recalls that year, nearly double the previous record held by General Motors.
The company faced a range of problems including:
- Accessory battery defects
- Door handle malfunctions
- Various technical glitches
- Loose electrical connections
- Door jamming issues
Most of the recalled vehicles were manufactured prior to 2023, before Ford launched a significant initiative to address its manufacturing quality concerns. The company has previously stated that approximately half of its recalls are resolved through over-the-air software updates that do not require owners to visit a dealership.
Market Performance Amid Safety Scrutiny
Despite the negative publicity surrounding these safety investigations and recalls, Ford's F-Series trucks maintained their position as America's bestselling vehicle overall. According to industry publication Car and Driver, the F-Series moved 801,525 units, demonstrating continued strong consumer demand even as federal scrutiny intensifies over transmission and other safety defects in these popular pickup trucks.
