Ford 7.3L Godzilla V8 Faces NHTSA Investigation Over Failures
The engine Super Duty and E-Series buyers picked specifically because it wasn’t going to strand them is now the subject of a federal safety investigation. NHTSA’s Office of Defects Investigation opened a formal probe on October 26, 2026, into camshaft and lifter failures in 2021-2022 Ford E-350 vans, F59 chassis trucks, and F-750s built with the 7.3-liter Godzilla V8.
What The Petition Actually Alleges
The petition that triggered ODI’s investigation isn’t posted publicly, but the complaints feeding it paint a consistent picture. One fleet owner in North Carolina reported that five of the 11 Ford vehicles in his fleet running the 7.3-liter V8 suffered engine failures, with the earliest at just 45,745 miles and the latest at 103,177 miles. That’s a failure rate most fleet operators would call unacceptable for an engine Ford marketed on durability.
The petition also claims Ford knew about the low oil pressure issue and responded with a software patch that raised idle speed, but allegedly never told owners the patch existed or why it mattered. For now, ODI is working to determine whether a defect actually exists before it moves any further. If it finds one, the next phase involves figuring out how widespread the problem is and what’s causing it, and only after that would a recall become possible.
Why A Cam Or Lifter Failure Is Such Bad News
A camshaft or lifter failure chews up metal inside the engine, and once lobes and rollers wear down that badly, the only real fix is a full engine replacement. For a Super Duty or E-Series owner who bought the 7.3L specifically to avoid diesel emissions headaches and expensive turbo or injector work, trading one catastrophic failure mode for another is the opposite of the pitch Ford made when it launched Godzilla for the 2020 model year.
The Godzilla lineup made its name on specs that back up the reputation: 430 horsepower and 475 lb-ft in Super Duty pickups, with van and chassis variants tuned lower for their duty cycles. Ford even built a 615-horsepower Megazilla crate version off the same architecture, which only raises the stakes if the base engine has a systemic weak point.
What Owners Should Do Right Now
There’s no fix and no confirmed recall yet, so there isn’t a dealer action to take today. What matters is that owners who’ve already paid for a cam, lifter, or engine replacement on an affected model send their repair paperwork to NHTSA. That documentation is part of how ODI measures how widespread a problem really is, and it’s often the difference between a quiet investigation closing with no action and one that escalates into a full recall.
One detail worth watching: Ford has changed the fuel pump part number on these engines at least six times since launch, which hints that later production runs may have already addressed whatever’s driving the oil pressure problem. That doesn’t help anyone with an early 7.3L already on borrowed time, but it’s a reason this may end up being a narrower fix than the vehicle count suggests.
