I noted that not sure why Ford dealer did not detect that nor the extremely dirty air filter nor the bad head gasket. They are on my radar if this not resolved.
Most Ford techs couldn't detect an oil leak if they were standing in a puddle of oil. Occasionally, you'll find one that really knows his stuff, but they're a rare breed.
Just got call from warranty company. They denied it because it was prior existing. Sounds like Obamacare
The ACA (aka Obamacare) actually
prevents insurance companies from denying coverage due to a preexisting condition. The impending repeal, however, may result in insurance companies being able to deny coverage for preexisting conditions once again.
I chose the 2009 Expedition because it was not an 08 or earlier. It is my understanding (from a lot research) that the engine and tranny that year addressed a lot of the issues you mentioned. And that the 2009 required a lot fewer repairs than earlier models.
To a degree, that's true but there are inherent problems in the design of the engine such as the plastic timing chain guides previously mentioned. Also, regardless of how good an engine design is, it can only take so much abuse.
My parents have a Mazda 3 that they purchased at the same time as our Mazda 6. It has the same engine and tranny as our Mazda 6. We have changed the oil every 5-6K, had the tranny flushed/filled as well and kept up on basic maintenance. Our 6 now has 185K on it and we have no reason to believe it's headed for the grave any time soon. Their Mazda 3 has 115K on the clock and sounds like it could explode at any moment. They change the oil every 12-18 months so by the time it's changed it looks like tar. Moreover, they
never check the oil so they could be running on 2 quarts for 8 months for all they know. They had a bad valve cover leak that was drowning Cylinder 1 and they failed to repair it for 3 years(!). After the repair they're still running that same spark plug that was drowning in oil for 3 years (really, it was nearly to the top of the spark plug well every time I checked it for them). It still has the original tranny fluid
and air filter. The care is 7 years old with 115K and it's still running the same air filter that it came with from the factory. The fact that the engine is running at all is a true testament to its quality, but there's no way it's going to last as long as ours with the abuse/neglect it has suffered.
