“Initially started in 2014 car seemingly locked up on me when exiting work place driveway and making right turn. Took car to airport marina Ford they keptt it for approx 2 -3 days unable to duplicate. Trouble has now reappeared in may and again today. Not sure what to do because of previous dealership case with them not being able to duplicate. I actually refused to take car back asking the the manager drive it around nothing found.”
NHTSA complaint #11000939, filed 2017-06, 71,671 miles“While leaving a parking lot and accelerating to barely 10 MPH, the left front brakes seemed to lock up and the car stuttered. After stopping and accelerating again, the problem did not reoccur at that time. The second time, I was leaving my driveway, again going no more that 10 MPH and the same thing happened, this time I noticed my traction control light flashing. I put the car into reverse, backed up a bit thinking I'd run over something, and accelerated again. Nope, didn't run over anything, just traction control seizing up. …”
NHTSA complaint #10651327, filed 2014-10, 48,000 miles“Our Ford FLEX came to a stop, (engine did not shut off) from approx. 10 MPH, without the driver, my wife, applying the brakes, in a mall parking lot. She shut it off and started it again. It drove fine. Since we have had brake issues with the FLEX before, we immediatly took the FLEX to the dealer. The dealer said they could find nothing wrong, even driving it 20 miles around town to replicate any problem. They also said they contacted Ford for any suggestions. We picked the car up two days later and my wife & daughter drove the car 350 miles to visit relatives. …”
NHTSA complaint #10409879, filed 2011-06, 25,577 miles“While entering a 4 lane divided highway from the driveway of a drugstore the electronic stability control (ESC) indicator light on the dash of my 2009 Ford FLEX began flashing and I could hear the buzzing of the antilock brake system (ABS). The vehicle was traveling less than 15 miles an hour at the time so there was no risk of the vehicle going out of control. The application of the brakes by the ESC/ABS prevented the vehicle from accelerating which I believe created a safety hazard while trying to pull out into traffic on the highway. …”
NHTSA complaint #10263718, filed 2009-03, 400 miles“Wife started car in school parking lot. Turned left and headed short distance the lot exit. While turning right onto the main road and starting to accelerate, heard 'load noises' that seemed to be under the car. Car started to slow down even though she was giving it gas. She pulled over and shut the car off. Didn't notice any dash lights (ABS or tcs). Restarted car and everything was fine. Car has 128,000 miles.”
