What 2009 Mercury Grand Marquis owners say
Brakes
An SUV crashed into an apple store in Hingham Mass. The driver told police his foot became stuck to the gas pedal. More likely his foot became hooked under the brake pedal as he tried to quickly shift his foot from the gas pedal up and to the left onto the brake pedal. This has happened to me several times after accelerating and then having to make a 'panic' stop. I had to quickly wiggle-foot from under to the top of the brake pedal. Brake pedals should be changed from a T shaped to a 7 shaped configuration. This would eliminate the hook. T configuration-the 'stem' is attached under the center of the brake pedal 7 configuration-the 'stem' is attached under the right edge of the brake pedal

About a month ago I contacted Beechmont Ford (600 Ohio Pike Cincinnati, Ohio 45245) in reference to Manufacturer Recall Number # 13S08 NHTSA Recall Number # 13V385000. I've wrote them three time and they have not responded. A week ago I chatted with Fords Hotline and they said they would do what they could. I've heard nothing back. Where do I go from here?
