First introduced for the 2021 model year, the sixth-generation Ford Bronco revived the iconic off-roader, bringing with it modern technology and improved 4X4 capability. Available in two- and four-door configurations, multiple trim levels, and several powertrain options, the new Ford Bronco is highly customizable, too. Now while this latest generation has been extremely popular, there are a few common issues on the Ford Bronco 6th Generation you should be aware of. Below is an overview of the most commonly reported concerns, along with maintenance tips on how to fix or even prevent them.
Engine Concerns
Some owners of the 2.7L V6 Bronco have experienced sudden engine power loss, knocking sounds, or complete engine failure, sometimes traced back to valve or valvetrain failures. Additionally, some 2.3L owners report mild turbo lag or abrupt throttle responses at low speeds. Software updates and ensuring the intercooler/hoses are leak-free can help.
Possible Causes & Fixes
- Valvetrain Failure (2.7L V6): Manufacturing inconsistencies or high engine stress can lead to early valve problems. Follow the recommended oil change intervals with high-quality synthetic oil. If you hear knocking or see a check-engine light, shut off the engine and get immediate service.
- Turbo & Intercooler Issues (2.3L I4): Minor boost leaks or sensor malfunctions can cause lag or power dips. Check intake hoses and intercooler connections for cracks or loose clamps.
- Carbon Build-Up: Direct-injection engines like these can accumulate carbon on intake valves over high mileage. Valve cleanings and using high-quality fuel can reduce deposits.
Transmission & Driveline Issues
A number of Bronco owners with the automatic transmission report rough shifting, especially when driving at lower speeds or during stop-and-go traffic. In many cases, a transmission control module (TCM) reflash or software update smooths out shifts.
For those with the manual transmission, the 7-speed can see quicker clutch wear if used heavily off-road or if the driver rides the clutch during slow crawling. Additionally, owners of early model Bronco vehicles with the manual report grinding and scraping noises at low temps.
Possible Causes & Fixes
- Transmission Control Software: Software calibrations can sometimes fix the abrupt shifts, especially on earlier model year SUVs.
- Clutch Wear (Manual): Repeated low-speed crawling or riding the clutch can accelerate wear. Consider an upgraded clutch kit for heavy off-road or towing applications.
- Transmission Grinding (Manual): If you experience a grinding noise during cold driving, you should expect it to go away after a few miles as the transmission warms up.
Suspension & Steering Concerns
Drivers who push the Bronco hard on difficult trails (especially with larger tires or lift kits) have reported bent tie rods or front-end clunks. Upgrading to aftermarket heavy-duty tie rods or steering stabilizers can mitigate these risks. Additionally, steering wheel vibrations or a “pull” at highway speeds may point to misalignment or unbalanced tires. Regular alignments, tire rotations, and checks on ball joints/bushings help maintain a smooth ride.
Possible Causes & Fixes
- Heavy Off-Roading Stress: The Bronco’s tie rods and steering components can bend or break under severe conditions, especially with oversized tires. Owners can upgrade to heavier-duty tie rods or steering stabilizers if they frequently tackle extreme trails.
- Wheel & Tire Issues: Misalignment or unbalanced wheels can cause highway vibrations. You should rotate and balance tires regularly and check that the alignment is within spec, especially if you’ve installed lift kits or larger wheels.
Body & Interior Rattles
Since the Bronco has removable doors, roof panels, and fender flares, minor rattles or squeaks can develop over time as clips loosen. Periodic tightening of hinges and adding foam tape or felt on high-contact points can reduce noise. The open-air nature of the Bronco can also allow extra dust or water to get inside. Keeping seals clean and lubricated helps reduce this intrusion.
Possible Fixes
- Loose or Worn Clips: Tighten hinges and latches, and add foam tape or felt pads where panels meet. Clean and lubricate seals to maintain a snug fit.
- Roof and Door Seals: Clean and treat rubber seals regularly. In extreme conditions, consider additional aftermarket weatherproofing solutions.
Maintenance Tips for the 6th-Gen Ford Bronco
One of the best ways to mitigate or even avoid some of these common issues on the Ford Bronco 6th Generation is by following the Ford Bronco maintenance schedule. By regularly maintaining your vehicle at the recommended intervals, you can prevent many problems early on. Here are just a few best practices we recommend to Bronco owners:
- Fluid Checks & Changes: Follow the recommended intervals for engine oil, transmission fluid, and coolant—especially if you tow or drive off-road.
- Inspect After Off-Road Use: Check the undercarriage, suspension, and steering components every tome you go off-road.
- Keep Software Current: Stay on top of over-the-air updates for engine, transmission, and infotainment improvements.
- Care for Seals & Tops: Clean and lubricate soft top hardware and door/window seals to reduce noise and leaks, especially if you remove them often.
- Aftermarket Add-Ons: If you install extra lights, winches, or other accessories, ensure they’re wired correctly to avoid battery drain or electrical gremlins.
