Driving down road at 45MPH, vehicle lost power, motor quite running. Due to being on 4 lane divided road, and cars all around, I quickly hit my hazard lights, put it in neutral and coasted best I could and was able to turn on a side road to safety. This was very dangerous. Dash lights were on, no warning lights, messages before, during or after event. Tried restarting vehicle and it cranked away. Figured out had to repush the push start button to keep it from cranking away longer. Towed to local Ford dealer. They determined cause to be Fuel Pump Driver Module failed, (explains engine stop since there was no fuel supply, and needed replacement. In addition I had another issue, they found water pump was leaking out weep hole. I then discovered they built the water pump into the engine block, behind the timing chain. It takes 13 hours to replace, and if you don't replace, the water goes into the engine oil. Very bad design, knowing it would need to be replaced. Cost over $2500 and 1 week to change a water pump! Ridiculous. I know a class action lawsuit has been filed-while not a safety issue directly, I think many people will not change it (due to expense), and then the engine blows up while driving creating a safety hazard.

Approximately 2 months ago car would not start. Towed to dealer on Friday. Dealer evaluated it on Monday but car resumed starting. Retrieved car. This morning problem returned. Having already done a lot of research on this apparently common issue it seems most of the time it is the fuel pump control module located behind the plastic trim on the passenger side B pillar. A replacement part was acquired from a Ford Parts Dealer and installed into the car. Car starts and runs fine now.

Car taken to Ford dealer who told us there was a tsb# 14-0091 for this issue.

I was traveling 70 mph on a toll way in busy morning traffic. Without any warning the vehicle lost engine power. Pressing the gas gave no acceleration and no power to move the car. Thankfully I was in the left lane and had enough momentum to get to the left shoulder. At this point a wrench light came on saying check manual. The car was under no power of its own in 70 mph traffic. Very dangerous! sat on the left should of the speeding toll road until a tow truck arrived and took it to the nearest dealership. They ran diagnostics and were very surprised and perplexed why a 2014 engine seized up. Issued a rental car for an indefinite time and said the engine will be taken completely a part as they try to figure out what went wrong. They said they will work with Ford on a solution whether to rebuild the engine or put a new one in. This is a 2014 engine! I think they know there is a big problem with the car. I certainly have lost confidence in it. It failed me at 70mph in traffic.
