Under the Hood: Ford Points Fingers at Aftermarket Mods for Faulty Bronco Differentials

Ford's Trail Turn Assist feature on the Bronco SUV has recently faced scrutiny as two drivers reported broken axle welds after utilizing the feature. Seeking clarification, we reached out to Ford to investigate their perspective on the issue. According to the automaker, they deny the existence of any problem altogether.

Understanding Trail Turn Assist and its Operational Requirements

Trail Turn Assist is a valuable feature designed to reduce the turning circle in tight spots during off-road adventures. It achieves this by selectively braking the inside wheel while allowing the outer wheel to turn. However, Ford emphasizes the vital importance of using Trail Turn Assist strictly within the performance window they have established. This necessitates the utilization of factory-approved parts in factory-approved situations.

Ford's Response: No Reported Trail Turn Assist Issues, Provided It's Used as Intended

When approached for comment, a Ford spokesperson stated that there have been no reported claims of Trail Turn Assist malfunctions when the feature is used as directed in the Bronco's owner manual, specifically on loose surfaces during off-road scenarios. Additionally, the spokesperson highlighted that if a Ford part fails due to an aftermarket product, Ford does not cover the cost of repairs or any associated damages. Furthermore, Ford emphasized that both Broncos involved in the original story had modifications.

Examining the Modifications: Baja Kits, Suspension Upgrades, and Tire Size

In one case, the owner had installed a Baja kit equipped with coil overs and bypass dampers. While there may be uncertainty among forum participants regarding whether these modifications void the warranty coverage, Ford asserts their position with confidence. In the other case, the Bronco featured a Baja suspension kit, specifically a long-travel Prerunner version comprising upper and lower trailing arms, along with 37-inch tires. It appears that these particular modifications are considered incompatible.

Warranty Exclusions: The Link Between Modifications and Broncos' Axle Weld Failures

When questioned about the exclusion of warranty coverage for these Broncos, Ford provided a concise response. They stated, "The photos of both Broncos show modifications that include new trailing arms, control arms, shocks, and bigger tires." This statement clarifies the basis for Ford's decision. Consequently, it appears that the ongoing debate has been resolved. Ford emphasizes that if Bronco owners wish to maintain their factory warranty coverage, they are free to engage in off-roading activities. However, adding the aforementioned modifications and expecting Ford to cover potential failures of Trail Turn Assist or similar features is not supported.

Ford's response sheds light on the issue of broken axle welds attributed to the use of Trail Turn Assist. It underscores the significance of adhering to Ford's guidelines for performance and using only approved components. Bronco owners should take note of the impact that aftermarket modifications can have on warranty coverage, ensuring they align with Ford's approved specifications for off-road adventures.
