2016 Ford Expedition engine problems

“The failed components are called "cam phasers." It is a known problem with the Ford 3.5 Ecoboost Engine (that even Ford is aware of). The cam phasers can fail, causing the timing chain to fail at any moment. They rattle upon startup of a cold engine. The failure of the original engineering is causing owners of this vehicle, along with the F150 and others, to have to spend anywhere from $3,000 to $5,000 in order to replace these. The problem has been confirmed by the Ford dealer. In order to visually examine the cam phasers, it requires something like 10+ hours to open the engine. You do not receive a warning light to replace cam phasers. It is merely an audio diagnosis. Ford SHOULD BE RESPONSIBLE for replacing these free of charge and replacing them with the newer versions of cam phasers, which apparently don't fail. Driving around with rattling cam phasers can leave you stranded!”

“The vehicle stops accelerating randomly it’s been in the shop (Ford dealer) a few times and they are unable to pinpoint the issue. The warning lamps would come on after the vehicle fails to accelerate. It would lose power at any interval and coast until it’s fully stopped.”

“I experienced the same problem you are investigating in F-150’s: I was traveling on the highway at 75 miles per hour on cruise control - there was a really loud thunk and the Expedition unexpectedly downshifted to a lower gear, I hadn’t touched anything and there was no warning. It was really scary and has made me doubt the safety of this Expedition.”
