U.S. auto safety investigators have expanded a investigation into Ford Motor Co. engine failures to include nearly 709,000 vehicles.

The National Highway Traffic Safety Administration also said in documents posted Monday on its website that it upgraded the investigation to an engineering analysis, a step closer to a recall.

The investigation now covers Ford's F-150 pickup truck, as well as Explorer, Bronco and Edge SUVs and Lincoln Nautilus and Aviator SUVs. All are from the 2021 and 2022 model years and are equipped with 2.7-liter or 3.0-liter V6 turbocharged engines.

Wow, interested to see how this plays out. This also explains why the first ST, 2021 that we didn't keep, we purchased used already had the engine replaced with only 1,700 miles.

I saw an article in the Associated Press about this, today

The automaker told officials that the defective valves were manufactured from a specific alloy called Silchrome Lite. The alloy can become excessively hard and brittle of they experience an “over-temperature condition” during the machining process. If an intake valve actually fractures, it is usually necessary to replace the whole engine due to the resulting damage.

Furthermore, Ford says that defective intake valves commonly fail early on in the engine’s life. In other words, most engine failures that will occur from this defect have already happened.

Just a after thought on that brittle part. Living in Hot Texas at Fort Cavazos could be a factor? Hope not however for many owners.

It was the kind of heat generated during the manufacturing process.

The engine on my 21 was replaced at 10k.. But was most likely a phaser issue.
