— Ford’s Nano EcoBoost engine recall affects 102,500 vehicles equipped with 2.7L or 3.0L Nano EcoBoost engine intake valves that could fail while driving.
Three safety defect applications ( here , here , and here ) were filed with the National Highway Traffic Safety Administration to determine if the Nano EcoBoost engine was defective.
In 2023, NHTSA expanded its previous investigation into Nano EcoBoost engine failures caused by intake valves.
The Ford Nano EcoBoost engine recall includes the following vehicles in the U.S. and Canada:
2021-2022 Ford Bronco
2021-2022 Ford F-150
2021-2022 Ford Edge
2021-2022 Ford Explorer
2021-2022 Lincoln Nautilus
2021-2022 Lincoln Aviator
If the intake valves become damaged while driving, the Nano EcoBoost engine could fail completely.
Ford describes the specific Nano EcoBoost intake valve engine issue as follows:
“The engines of the affected vehicles may contain intake valves that are susceptible to cracking and breaking. The engine intake valves may have grinding burns and hardness that exceeds specifications in the third retaining groove position of the valve.”
Before losing power, the driver may see an engine warning light or notice that the engine runs rough.
Ford is aware of 811 warranty claims worldwide related to intake valve cracks as of Aug. 9, 2024. The automaker is also aware of at least 267 field reports and 233 customer complaints regarding intake valve cracks.
However, Ford has not received any reports of crashes or injuries related to intake valve damage on 2.7L and 3.0L Nano EcoBoost engines.
Ford Nano EcoBoost recall letters will be mailed on October 7, 2024, and dealers will conduct engine cycle tests and replace the engine if necessary.
This test will determine the “Cumulative Engine Cycles” of the engine.
“For vehicles that do not meet the engine cycle threshold, dealers will accumulate high rpm engine cycles per the service procedure. Vehicles that do not pass the engine cycle accumulation will have their engines replaced.” – Ford
