What caused the engine failure on the Ford Bronco?

Ford Bronco Engine Failure
The engine failure on the Ford Bronco has been primarily attributed to issues with the second-generation 2.7-liter EcoBoost V6 engine, which is installed only in the Ford Bronco and F-150. The problem has affected the SUV more than the pickup truck and has been linked to the valves dropping into their respective cylinders, causing serious internal damage and loss of compression.
According to reports, the valves used in the 2.7-liter V-6 were supplied by an outside vendor to Ford’s Lima plant, and a defect caused them to become brittle from the heat of combustion over time. It has been suggested that a bad batch of valves made in April was the root cause of the issue.
The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into the 2021 model year Ford Bronco SUVs powered by the 2.7-liter EcoBoost V6 due to the potential for catastrophic engine failure related to a faulty valve within the engine [[5]].
In addition to the valve issue, there have been claims that Broncos equipped with the 2.7-liter V6 also suffer from a bad oil pan design that may let the oil pickup tube suck in air, potentially contributing to the engine problems.
Ford is still investigating the issue, and affected customers will be covered under the vehicle’s warranty.
