Example complaints

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

“When I drive my vehicle & apply the brake, the brake pedal vibrates & the rpms increase and the vehicle stalls out. When my heat is on high whether vents or the floor, and apply the brake while driving, the brake pedal vibrates and the rpms increase and the vehicle stalls out.”

NHTSA complaint #11054115, filed 2017-12, 79,650 miles

“I was driving at low speed, around 10 to 15 MPH, getting ready to make a turn and the car died. It was overcast and the lights were on. The whole dash went black and I had no power steering or brakes. I pulled into a parking lot without someone hitting me. After stopping, I put the car in park and was able to restart and drive home. Today, the day after the car died, I called my dealer. He stated they cannot repair it if the issue can't be duplicated. The car has 103,00 miles and this is the first time it has ever happened. …”

“As indicated by a number of FLEX owners, my FLEX simply died in the middle of the freeway going 70 MPH. No warning - lights on dash went on, lost all power including power steering. After muscling the car to the shoulder, putting in park and sitting for a few minutes, it started back up. Took to dealer who said they could find nothing wrong. Extremely dangerous. I was almost rear ended. How many different people need to be affected by this problem before Ford and NHTSA take action.”

NHTSA complaint #10721761, filed 2015-05, 90,000 miles

“Got in my car and when I started the vehicle the air bag light along with the traction control indicator light came on, took it to a dealer to see what the issue was and was told it is the restraint control module and to replace it will cost 900.00. This is obviously a faulty part and should be covered as it directly controls the sir bags and the seat belts. So because I do not have 900.00 laying around I g=have to hope I am not in a collision until I can come up with the ridiculous amount of money to replace a plug in module that costs less than 100.00 to manufacture.”

NHTSA complaint #10631013, filed 2014-09, 56,000 miles

“Accelerating on interstate ramp, vehicle stalled and shut off. It would not stay running. It sputters and dies after cranking. We had aaa tow it off the roadside after 90 minutes waiting.”
