2006: “I was driving my 2006 Mercury Mariner Hybrid down the road going approximately 35-40 MPH. The vehicle shut off and the dash read stop safely now. I could still steer and brake. It would not restart right away. I tried restarting in about a half an hour and it started. I then drove for approximately 100 yards and the vehicle shut off again and the same dash reading . …”
NHTSA complaint #11155944, filed 2018-12, 258,603 miles2010: “I have been on the phone with ford. An extremely mad and rude woman didn't or couldn't answer any questions I had. She kept telling me I got my recall be cause they checked my computer system but didn't replace the recalled steering module. The woman also didn't hang up so I was unable to do the survey at the end of the phone call. Some people are disgusting the way they treat others.”
NHTSA complaint #10984259, filed 2017-05, 84,000 miles2008: “The power torque sensor for the power steering was already recalled and had the system updated before I got the car in 2014. The cars steering wheel starts shaking a little then all of a suddle the steering wheel locks up and the power steering stops working, so you can't hardly turn it. I came inches from getting in a wreck. You can update the system but it will only work for about 1 or 2 years.”
