Low-pressure fuel pump failure. Closed sep 19, 2025, led to recall 25V-455.

NHTSA summary
On July 29, 2024, the Office of Defects Investigation (ODI) opened PE24019 to investigate complaints of low-pressure fuel pump failures in MY 2021 Ford Bronco vehicles. Some consumers reported that the failure occurred without warning while driving, resulting in a complete loss of motive power with no ability to restart the engine. Ford determined that several other vehicle models contain low-pressure fuel pumps substantially similar to the 2021 Ford Bronco, including the 2022-2023 Ford Bronco, 2018-2023 Ford F-150, 2022-2023 Ford Expedition, 2019-2023 Lincoln Navigator, 2020-2023 Ford F-250-F-550, 2024 Ford Super Duty Chassis Cab, 2024-2025 Ford Ranger, 2020-2023 Ford Explorer, 2020-2023 Lincoln Aviator, and 2021-2025 Ford Mustang. ODI's investigation found that the affected vehicles may lose fuel pressure and flow from the fuel delivery module (consisting of a low-pressure fuel pump, jet pump, reservoir, and other parts) due to a low-pressure pump failure. This can cause the engine to stall while driving. The root cause is reduced internal clearance in the fuel pump, increasing friction and sensitivity to vapor lock. Fuel blockage from contamination inside the jet pump also contributed to the failure. Ford stated that the contamination source was unknown. On July 7, 2025, Ford filed recall 25V-455 for certain 2021-2023 Ford F-550 SD/F-450 SD/F-350 SD/F-250 SD, 2021-2022 Lincoln Navigator, 2021-2022 Ford Mustang, 2021-2022 Ford F-150, 2021-2023 Ford Explorer, 2022 Ford Ex

Unexpected transmission downshift. Closed oct 22, 2019, led to recall 19V-075.

NHTSA summary
The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of transmissions unexpectedly downshifting to a lower gear without input from the driver on model year (MY) 2011-2013 Ford F-150, Expedition and Navigator vehicles. ODI has received 455 unique reports related to the alleged problem that were not covered under a previous recall for this issue (16V-248).Expedition and Navigator complaint rates are lower than F-150 complaints. Of those 455 reports, 34.7% claimed that the rear wheels locked up when the transmission downshifted. There were 4 accident claims with no injuries. There are many instances where drivers report leaving their lane or the road because of this issue.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 783 unique reports related to the alleged problem. There were 6 accident claims with 3 injuries. Ford also submitted 1206 warranty claims related to transmission downshifting failures. The failure can occur at any time, but typically at higher speed, and include symptoms such as sudden transmission downshifting, loss of speedometer, erratic shifting of transmission, and transmission stuck in one gear. The failures typically occur without warning and may result in the rear wheels momentarily locking up. The driver often had to fully stop the vehicle and restart it to get the vehicle to shift properly.On February 2nd, 2019 Ford notified ODI that it would conduct a safety recall

What owners wrote

“Sudden and severe downshifts occurred at roadway and highway speeds resulting in sudden speed decrease. Also revving and loss of power occurred. Problem codes P0706 & P0707 were logged which point directly to the Transmission Range Sensor (TRS), which is integrated into the molded lead frame. This sudden and uncontrolled loss of speed caused significant danger to vehicles, ocupants, and other vehicles.”

Filed Apr 22, 2026

“TSB 23-2143, citing cold-start cam phaser rattle as a manufacturing defect that impacts reliability and safety (loss of power, premature wear, noise).”

Filed Jul 11, 2025

“While attempting to accelerate, was not able to. Vehicle lost all power. Had to pull over and turn vehicle off and then back on. Happened twice in about 15 minutes. This is the 3rd time in 2 years this has occurred. Brought into repair facility and the issue is the throttle body.”

Filed May 5, 2022

“Loss of power, no throttle response while driving. Happens when the throttle is advanced at a faster pace like taking off from a traffic light. I get the "See Manual" message and the wrench symbol. Turning off and then turning back on the vehicle clears the fault. Known problem with the Throttle body.....Can you say Recall?”

Should you keep driving it?

This page can't tell you that. 1 of 35 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
