Front Axle Vibration/Boom Noise Above 50 MPH
Some 2022 Ranger 4x4 vehicles exhibit a noticeable vibration and booming noise at highway speeds above 50 mph, originating from the front end. The vibration is felt through the steering wheel and floorboard and is caused by an imbalanced front axle assembly.
Ford issued a TSB to replace the front axle assembly with a balanced unit. The dealer will verify the vibration matches the TSB conditions and replace the front differential/axle assembly. This is typically covered under the powertrain warranty.
Est. Cost: $0 under warranty; $1,500 - $3,000 if out of warrantyRear Axle Shudder/Vibration from Stop
2019-2023 Rangers can exhibit a shudder or vibration when accelerating from a stop, particularly in the 15-25 mph range. The shudder is caused by excessive rear axle pinion angle and feels like driving over rumble strips.
Ford issued a TSB addressing the rear axle pinion angle. The repair involves installing an updated rear leaf spring spacer or adjusting the rear axle alignment. A rear differential fluid change with friction-modified lubricant may also help.
Est. Cost: $200 - $600Windshield Bonding Defect (Recall)
Certain 2022 Bronco and Ranger vehicles have windshields that were not properly bonded to the frame during manufacturing. In a crash, the windshield could detach, compromising airbag performance and increasing ejection risk.
Ford issued a recall to rebond or replace the windshield with the correct adhesive. Contact your dealer to check your VIN. The repair is performed free of charge.
Est. Cost: Covered under recallTransmission Selector Shaft Seal Leak
2022 Rangers built on or before July 31, 2022 with certain automatic transmissions may develop a transmission fluid leak from the selector shaft seal. Owners may notice reddish-brown fluid spots under the vehicle and low transmission fluid warnings.
Ford issued a TSB to replace the transmission selector shaft seal with an updated design. Check the transmission fluid level regularly and top off with the specified Mercon ULV fluid until the repair is completed.
Est. Cost: $150 - $400Loose Fuel Line (2.3L EcoBoost, Recall)
Some 2022 Rangers with the 2.3L EcoBoost engine may have a fuel line that was not properly tightened during manufacturing. The loose connection can result in a fuel leak, fuel odor, and an increased risk of engine compartment fire.
Ford issued a recall to inspect and tighten the fuel line fitting. Contact your dealer to check your VIN. If you smell fuel, do not drive the vehicle and have it towed to the dealer. The repair is free of charge.

An electrical short circuit can increase the risk of a fire.
Owners are advised not to plug in their block heater until the vehicle is remedied. Dealers will replace the block heater, free of charge. Interim letters, notifying owners of the safety risk, were mailed December 3, 2025. Additional letters will be sent once the final remedy is available, anticipated February 2026.

BACK OVER PREVENTION:SOFTWARE
Ford Motor Company (Ford) is recalling certain 2018-2022 Transit Connect, 2019-2020 MKZ, MKX, Edge, Continental, F-150, Nautilus, Fusion, 2019-2023 Ranger, Mustang, 2020-2021 EcoSport, Expedition, Navigator, 2020-2022 Escape, F-250 SD, Corsair, 2020-2023 Aviator, Transit, 2020-2024 Explorer, 2021-2024 Bronco Sport, and 2022-2024 Maverick vehicles. A software error may cause the rearview camera to display a blank image, or the image may remain on the display after the backing event has ended.
A rearview camera that displays a blank image can reduce the driver's view behind the vehicle. A rearview image that continues to be displayed after the vehicle is shifted out of reverse may distract the driver. Both of these situations can increase the risk of a crash.
Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed September 4, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S72.
EQUIPMENT:OTHER:LABELS
Ford Motor Company (Ford) is recalling certain 2022-2023 Bronco, 2023 Super Duty F-250, and 2019-2023 Ranger vehicles. The Tire and Loading Information (TREAD) label states the incorrect load carrying capacity, which can result in an overloaded vehicle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
An overloaded vehicle increases the risk of a crash.
Ford will mail a new TREAD label to install over the existing label, free of charge. Owners will also have the option to take their vehicle to a Ford or Lincoln dealer to have the new label installed, free of charge. Owner notification letters were mailed July 21, 2023.

FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: RADAR
Ford Motor Company (Ford) is recalling certain 2021 Ranger and Bronco vehicles. The cruise control radar module was misaligned during production.
A misaligned radar module may prevent the vehicle from maintaining a safe distance from other vehicles when adaptive cruise control is active. In addition, the automatic emergency braking (AEB) system may react slowly, or not react at all, during a pre-collision assist braking event. Any of these scenarios can increase the risk of a crash.
Dealers will adjust the angle of the cruise control radar module, free of charge. Owner notification letters were mailed January 21, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21S52.
SEAT BELTS:FRONT:WEBBING
Ford Motor Company (Ford) is recalling certain 2019-2021 Ford Ranger Super Cab vehicles. The front passenger outboard seat belt may not have been assembled properly, allowing the seat belt to be misrouted. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 208, "Occupant Crash Protection" and 209, "Seat Belt Assemblies."
A misrouted seat belt may not adequately restrain an occupant in a crash, increasing the risk of injury.
Ford will provide owners with instructions to perform a preliminary inspection of their front seat belts. Owners that detect an issue with the driver's seat belt, are unsure of the results, or do not want to perform an inspection, should not drive their vehicles and contact a Ford dealership.

SEATS:MID/REAR ASSEMBLY
Ford Motor Company (Ford) is recalling certain 2020-2021 Ranger Super Cab vehicles equipped with rear seats containing fixed head restraints. The fixed head restraints may interfere with proper installation of certain types of child seats. Additionally, the child seat may not attach properly to the lower-rear anchors. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage System."
An improperly attached child seat can increase the risk of injury in a crash.
Dealers will inspect the rear-lower child restraint anchorages for correct alignment and adjust as necessary. Separately, dealers will replace the non-removable head restraints with removable head restraints, free of charge. Interim owner notification letters were mailed on November 5, 2021.
