Ford’s Engine Teardown Program Is Already Changing Its Warranty Data
Ford has been tearing down one engine per day at every manufacturing plant — and the warranty data is already moving in the right direction. The program, which the automaker expanded across all plants after its Valencia Assembly facility quietly proved the concept, marks a deliberate shift from reactive recall management toward diagnostic precision.
The timing matters. Ford has routinely issued more recalls than any other automaker in the United States for roughly six years running, a pattern that has frustrated owners and drawn scrutiny from regulators. The daily teardown initiative is Ford’s most concrete answer yet to the question of whether it’s actually fixing systemic problems — or just processing paperwork.
How the Daily Teardown Program Actually Works
The program is straightforward in concept but a meaningful operational change in practice. At each Ford engine plant, one engine is pulled directly from the assembly line every day and fully disassembled so engineers can examine components for wear patterns, tolerances, and early failure indicators — before any vehicle reaches a customer.
That replaces a previous 90-day teardown cadence, or ad hoc teardowns whenever plant managers flagged a concern. The Valencia Assembly plant in Spain, which builds the 2.3-liter EcoBoost four-cylinder among other engines, had already been running daily teardowns informally. Its quality metrics outpaced other facilities, and Ford took notice. The practice became standardized company-wide from there.
Ford is also using AI to determine which specific engine from the production run gets selected for teardown each day — rather than pulling units at random. The goal is to surface statistical outliers that might otherwise blend into normal production variance.

Which Engines Are Under the Microscope
Neil Wilson, manager of Ford’s Essex engine plant, confirmed the program’s scope in a conversation with Road & Track. The Essex facility is responsible for the 5.0-liter Coyote V8, the 6.8-liter V8, and the 7.3-liter V8 — engines that power the Mustang GT, F-150, Super Duty, and Transit applications. Those powerplants represent a wide range of duty cycles, from daily commuters to heavy tow rigs, which makes teardown data especially valuable for identifying stress points that don’t show up in standard bench testing.
The 2.3L EcoBoost four-cylinder is also a priority given its breadth of application — it’s fitted to the Bronco, Ranger, and Explorer — and a recent recall tied to that engine affects all three nameplates. EcoBoost variants in general carry more thermal and boost-related complexity than naturally aspirated engines, making them higher-risk candidates for the kind of incremental wear that teardowns can catch early.

What The Warranty Data Is Starting To Show
Wilson confirmed that warranty claims have declined since the daily teardown program rolled out, and recall rates have dropped alongside them. Ford COO Kumar Galhotra has separately pointed to a parallel change in engine testing philosophy: Ford now runs engines until they fail, rather than stopping tests at a predetermined simulated-mileage threshold. That shift means failure modes that previously only surfaced in the field are now being captured in the lab.
Together, the two changes — daily teardowns and failure-mode testing — represent a move toward understanding root causes rather than managing consequences. A recall addresses vehicles already in service; teardown data can prevent the failure from reaching production in the first place. For owners of current EcoBoost-equipped trucks and SUVs, the practical implication is that late-model Fords are being built under tighter scrutiny than their predecessors.
Ford still has ground to recover, as years of high recall volume don’t reverse overnight. But the teardown program is a measurable structural change, not a PR statement, and the warranty trends are pointing in the right direction. Owners tracking Ford’s reliability trajectory have a concrete data point to watch.

TopSpeed’s Take
Ford has spent the past few years as the industry’s punching bag for recalls, so a program built around finding problems before they leave the plant is exactly the kind of unglamorous, behind-the-scenes work that actually moves the needle. Tearing down a fresh engine every single day is the difference between a company managing its image and one rebuilding its engineering discipline from the inside out. Using AI to target the units most likely to reveal a problem rather than pulling random samples is an interesting approach, and a tool Ford probably didn’t have at its full disposal before. Hopefully, Ford is able to gain some momentum and soon shed the ‘most recalls in America’ crown.
