I Have a 2015 SEL v6 (its a fleet vehicle). Got it on 1/1/16 and now has 11k miles on it. That squeaking when turning off is the accessory belt. I havent found out if its pulley, idler, or belt but thats where it is. Not a big deal I guess.
Ive had it die on me twice though driving 75mph on i95. First time dealer said it was a vapor valve stuck open and engine went into safe mode, but it appears that wasnt the case. It happened a second time and this time the dealer identified a throttle body malfunction. Turns out Ford is waiting, at the moment, for 2600 back ordered units for SUVs down across the US. My edge was down for 4 weeks waiting on the part. Thankfully I got it back last week and my company paid for a rental in the interim. Just be alert if you are driving and lose power. The dealer said the 2016s have the new throttle body and dont have the issue.
Best of luck with your issues.
