Owners of certain 2021-2025 Ford Bronco SUVs should be aware of a newly announced safety defect affecting the vehicle’s powertrain. Identified under NHTSA Campaign Number 26V-236, this issue impacts approximately 4,922 vehicles and centers around a potentially serious problem with the connection between the transmission and transfer case.
What’s the Problem?
The recall stems from a misalignment that can occur during previous service repairs involving the transmission or transfer case. If these components are not properly aligned when reassembled, it can lead to premature wear of critical internal splines, specifically the transmission output shaft splines and transfer case input splines.
Over time, this wear can reduce the ability of these parts to properly transfer power from the engine to the wheels.
Why This Matters
If the spline wear becomes severe, drivers may experience:
- Loss of motive power while driving
- Failure of the vehicle to properly engage “Park”
- Vehicle rollaway if the parking brake is not applied
These conditions significantly increase the risk of a crash, particularly if the issue occurs unexpectedly while driving or when the vehicle is parked on an incline.
Warning Signs to Watch For
Ford notes that affected drivers may notice early warning symptoms before a failure occurs, including:
- Grinding noises
- Clunking sounds
- Unusual vibrations
If you’re experiencing any of these issues—especially after recent drivetrain service—it’s worth getting your vehicle checked immediately.
How Ford Discovered the Issue
Ford first flagged the problem in November 2025 after reviewing warranty claims on 2022–2023 Bronco models reporting noise, vibration, and drive engagement failures. By December, the issue was escalated internally, and a deeper investigation revealed similar cases across 2021-2025 models.
Engineers ultimately determined that improper alignment during past repairs was the root cause. Testing confirmed that even slight misalignment could reproduce the same wear patterns seen in failed components.
To address this, Ford updated its service procedures on February 26, 2026 to ensure proper alignment during repairs going forward.
How Many Vehicles Are Affected?
While nearly 5,000 vehicles in the U.S. had undergone relevant repairs prior to the updated procedures, only a small number of confirmed cases have been reported so far 26 vehicles globally as of March 2026.
What’s the Fix?
Dealers will:
- Inspect the transmission-to-transfer case joint
- Replace the transmission and/or transfer case if necessary
Recall Timeline
- April 27, 2026: Interim notification letters sent to owners
- July 2026 (anticipated): Final remedy available and follow-up letters sent
Ford has assigned this recall the internal number 26S26.
What Should You Do?
If you own a 2021–2025 Bronco:
- Watch your mail for official recall notifications
- Pay attention to any unusual drivetrain noises or behavior
- Always use your parking brake when parked (especially on inclines)
- Contact your local Ford dealer if you have concerns
Final Thoughts
This recall highlights how even routine service work can introduce issues if not performed precisely—especially in complex drivetrain systems. While the number of confirmed cases is relatively small, the potential safety risks make this an important issue for Bronco owners to take seriously.
