There is far to much to list.

2 Power Train problem

Failure Date: 05/26/2023

The power transfer unit otherwise referred to as a transfer case exploded from the inside with under 50k miles on the Flex resulting in the transmission cracking and breaking as well. Aaa inspected and replaced both transmission and transfer case. They say they see a lot of them for these models and is a common issue. We kept old transfer case as proof. Car is not used for towing as it has no hitch and as stated before had under 50000 miles when it destroyed itself with myself and kids in the car driving 45 mph.

3 Power Train problem

Failure Date: 01/15/2019

Ecoboost 3. 5l vehicle experienced total loss of power and white smoke from tailpipes while driving 65mph on expressway but still ran. Drove straight to an independent service center where they diagnosed low boost pressure dtc and failure of both turbochargers. Towed vehicle to Ford service center where they dug deeper and are now telling me there was a coolant system leak which washed out the engine oil and caused the engine to overheat and the turbos to fail(lock up). There have been numerous documented issues with coolant system leaks and oil supply to turbos causing failures/fire/overheating in ecoboost engines. . . Dealer is now telling me the entire engine needs to be replaced including the turbochargers in the ballpark of $13,000.
