2016 Ford Flex Engine Problems

“The vehicle was in motion and was turning left from a stop at a stoplight. We were preparing to enter a highway on-ramp. The engine suddenly quit (no warning) and would not restart. Had this happened a few moments later (merging into heavy highway traffic), an accident would have been likely. We were not able to restart the engine and the vehicle had to be towed. It only has 31,000 miles. It gave no signs of impending problems, the engine failure was completely without warning. (there was plenty of fuel in the tank also).”

“Takata recall my engine light went on 2000 miles before my manufactures warranty expired. I have a Ford shop here, but they are rated so low and I hear nothing but bad stuff about them, so I called the next closest 95 miles away in spearfish, sd.

I have 36,879 miles on my 2016 and either have an exhaust leak from the headers or the manifold. …”

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). …”

“I am getting a Transmission Not In Park error that will also sometimes flash Door Ajar while driving. Door appears to be closed - not sure if it's latched, transmission is obviously NOT in park because the car is moving. I'm concerned that this shouldn't be driven and is a safety issue.”

“Ford hid the fact that some of its vehicles may suffer a sudden internal water pump failure that poses significant safety risks to drivers including sudden catastrophic engine failure. From 2007 through at least 2020, Ford has incorporated the Cyclone Engine—containing a faulty internal water pump—into thousands of vehicles. Internal Water Pumps should last for the useful life of the engines without the need for any service, maintenance, or repair. …”
