Steering

5 reports2 related recalls
“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?”

Service brakes

4 reports1 crash
“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”

Electrical system

4 reports1 fire
“ON OCTOBER 21, 2016, WHILE I WAS DRIVING ON I-30 IN DALLAS COUNTY, A FIRE OCCURRED IN THE DAIMAY-SUPPLIED DRIVER-SIDE VISOR LAMP ASSEMBLY OF MY 2009 FORD MERCURY GRAND MARQUIS. THE FORD FUSE SYSTEM FAILED, ALLOWING THE FIRE TO BURN, MELTING PORTIONS OF THE VISOR AND ROOF MATERIAL. THE MELTED MATERIAL FELL ON MY LEFT LEG AND THE DRIVER SEAT AND FLOOR OF THE VEHICLE, CAUSING 2ND AND 3RD DEGREE BURNS TO MY LEG. CHRYSLER NOTIFIED NHTSA OF A SIMILAR DEFECT IN THE DAIMAY ASSEMBLY ON JULY 1, 2014, WHICH RESULTED IN THE FIRST OF TWO CHRYSLER RECALLS ON JULY 10, 2014. FORD, HOWEVER, CHOSE TO NOT RECALL ITS VEHICLES WITH THE DAIMAY VISOR ASSEMBLY SYSTEM, DESPITE RECEIVING NOTICE OF SIMILAR COMPLAINTS, CLAIMS AND INCIDENTS BEFORE THE SUBJECT INCIDENT. THEREFORE, I RESPECTFULLY REQUEST THAT THIS DEFECT BE PROMPTLY INVESTIGATED AND THAT THE UNSAFE SYSTEM BE RECALLED SO THAT OTHER CONSUMERS ARE NOT INJURED.”

Fuel/propulsion system

2 reports
“I NOTICED SOMETHING HANGING DOWN FROM THE BOTTOM OF THE VEHICLE AND ON INSPECTION DETERMINED IT TO BE A FUEL TANK SUPPORT STRAP. I TOOK THE VEHICLE TO MY MECHANIC FOR FURTHER INSPECTION AND WHEN HE PUT THE VEHICLE ON A LIFT ONE OF THE TWO SUPPORT STRAPS HAD CORRODED COMPLETELY IN TWO AND THE OTHER STRAP WAS LY CORRODED NEARLY AS BAD. IF THE SECOND STRAP HAD ALSO BROKEN AND ALLOWED THE FUEL TANK TO DROP AND DRAG ON THE PAVEMENT THERE COULD HAVE BEEN A SEVERE FIRE. I HAD MY MECHANIC REPLACE BOTH STRAPS IMMEDIATELY TODAY 11-2-16.”
