My wife and I own a 2015 Ford Edge with approximately 65k miles. It is a daily driver for my wife. The vehicle started making a bad rattling noise a couple days ago. We already had an appt. For an oil change at the local Ford dealership so I told her not to drive it and to have them check it out when she took it in. Upon arrival to the Ford dealership, the technician popped the hood, listened for a moment and replied, "I'm 99. 9% sure I know that noise". He further explained they would need to get a bore scope and look at the flex plate as these vehicles have had and are having issues with the flex plates cracking/breaking. They kept the vehicle most of the day and called back later that evening stating that's what it was and they needed to pull the transmission to determine how much damage was done. The next day the dealership called back stating it has to has a new engine due to flex plate failure, again. The cost of the repairs are estimated to be $5600 as it is out of warranty. The Ford dealership also stated this will be the 3rd flex plate that this vehicle will have had: repaired in 2017, repaired in 2018 and now 2020. So this will be the 4th flex plate this vehicle has seen in 5 years counting the original one. My wife originally heard the noise when she started it at work to go pick up our toddler from day care. It is very loud at idle, sort of sounds like a diesel engine. I'm very thankful (and according to the Ford dealership) this did not happen on the highway as she could have lost all power to the vehicle causing an accident.
