Ford will recall 90,736 automobiles as engine consumption valves within the automobiles could break whereas driving, the Nationwide Freeway Visitors Security Administration (NHTSA) mentioned on Saturday. The recall impacts sure 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator automobiles geared up with both a 2.7L or 3.0L Nano EcoBoost engine, the NHTSA mentioned.
In line with paperwork posted by NHTSA and sourced from the automaker, “The engine consumption valves could break whereas driving, which can lead to engine failure and a lack of drive energy.” Following an investigation that began in January, 2022, Ford discovered 22 situations the place “the engine consumption valves fractured and fell into the combustion chamber of the engine inflicting catastrophic engine harm.”
The automaker’s evaluation continues: “Ford recognized that the potential root explanation for the failures was engine consumption valve failure because of valves that exceeded the designed specification for hardness, had been brittle, and extra more likely to fracture. Ford decided that this was because of the provider’s grinding processes and the sensitivity of the consumption valve materials to grinding processes that weren’t inside management specs. The consumption valve materials was modified for automobiles produced after October 31, 2021.”
Fixing the issue would require substitute of the whole engine. “Sellers will examine every car to find out its cumulative variety of engine cycles. For automobiles that don’t meet the engine cycle threshold, sellers will accumulate excessive revolutions per minute (rpm) engine cycles per a service process. Engines might be changed on automobiles that don’t cross the engine cycle accumulation,” Ford says.
