Example complaints

Vehicle speed control: “Was stopped at a red light, car had been driving fine, but when the light turned green and I proceeded my car suddenly had reduced power and would not drive more than 40-45 MPH. No lights or anything came on the dash the first time. The second time however a yellow/orange wrench light appeared. I got home and parked for the remainder of the day but then the following day the problem still proceeded and I then let it sit all weekend. The following monday I turned it on to take to the repair shop and the car drove fine that entire day. …”

Steering: “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.”
