Fun story, we ended up with a 2019 Expedition Limited for a crazy low price ($30,000). I knew the cam phasers were probably wearing out, but at that price I could eat $4000 in repairs and still be ahead.
1 week later the check engine light comes on. Cam codes and cat converter. I take to the dealer (who had a 3 month 3K mile warranty on it). Turns out it needs the cam phasers and the catalytic converter replaced. Total price is about 5K. They are currently sending it down to there Ford dealer to perform the work. So it looks like it’s all going to work out. Only downside is I’m paying on a vehicle I can’t actually use at the moment.
