Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“It has happened since 2012 sept, when I bought it at 4000km. I was about to start from a traffic light. I let go my brake and 'slightly' onto gas. Nothing at all happened. I push a bit harder and it crank into another gear as I felt like 'galloping'. I brought it to the body shop I knew (8 pm) and was told to go to dealers for transmittion check up. Did so, in 3 days - 'no code' no problem. …”

“Ptu failure - I have had my FLEX since 2012. I have never had an issue with anything in that vehicle. I am in the military, and I travel a lot. I have that oil changed and tires rotated religiously. Fluids are always topped off. I just turned over 120,000 miles on my 2011 FLEX, 85 percent of those miles were highway. My FLEX started hesitating, occasionally. An occasional jerk into gear. Then started making metal-grinding noises, then sputtering. This happened over a 3 month period. I find out my ptu is shot, of course I am over the mileage for the warranty - shocker. …”

“Transmission on FLEX often hesitates and thunks with a lurch. The lurch is so bad it now feels like we are being hit. It has happened in both forward and reverse. Tried to get it repaired twice at dealer - haven't been able to fix. Online forums with owners and service bulletins describe similar problem. Ford not acknowledging issue or helping.”

NHTSA complaint #10484463, filed 2012-11, 34,000 miles

“From a stop, transmission slipped, banged into 1st (or 2nd gear), did it again around 50 MPH, felt like the tranny slipped and then banged into gear. The banging into gear is a violent lurch. Took it to Ford told nothing wrong with vehicle (even though I had prior TSB's on same tranny issues in 01/2011 build cars). Started in 2012, was intermittent until recently and has happened several times over past month.”
