ON APRIL 3, 2006, FORD MOTOR COMPANY SUBMITTED A DEFECT INFORMATION REPORT TO NHTSA CONCERNING A DEFECT CONDITION THAT COULD RESULT IN INTERFERENCE BETWEEN THE ACCELERATOR PEDAL AND FLOOR CARPETING IN APPROXIMATELY 19,140 MODEL YEAR 2003 AND 2004 MUSTANG COBRA VEHICLES (FORD RECALL NO. 06S43/NHTSA RECALL 06V-108, COPY ATTACHED).FORD WILL RECALL THE VEHICLES TO INSTALL A SHIELD BENEATH THE ACCELERATOR PEDAL TO PREVENT THE PIVOT PIN ON THE REAR SURFACE OF THE PEDAL FROM COMING INTO CONTACT WITH THE FLOOR CARPETING DURING HEAVY THROTTLE APPLICATION.IN THOSE VEHICLES WHERE THE FLOOR CARPETING DOES NOT FIT FLUSH WITH THE SHEET METAL, THE UNIQUE REAR SURFACE PROFILE OF THE MUSTANG COBRA PEDAL MAY ALLOW THE PIVOT PIN OF THE PEDAL TO CATCH IN THE CUTOUT ON THE FLOOR CARPETING BEHIND THE PEDAL, INTERFERING WITH THE PEDAL'S ABILITY TO RETURN; THE RESULT OF WHICH COULD BE UNEXPECTED, CONTINUED THROTTLE APPLICATION.DURING THE ENGINEERING ANALYSIS STAGE OF THE INVESTIGATION, ODI ALSO EXAMINED THE POSSIBLITY OF THE SAME PHENOMENA OCCURING IN NON-COBRA MUSTANGS.HOWEVER, THE DIFFERENT DESIGN OF THE ACCELERATOR PEDALS ON THE NON-COBRA MUSTANGS RESULTS IN SIGNIFICANT DIFFERENCES IN THE POTENTIAL CONTACT BETWEEN THE ACCELERATOR PEDAL AND THE CARPETING, WITH THE BASE OF THE PEDAL PAD ACTING TO FORCE THE CARPET AWAY FROM THE PIVOT PIN.THIS ENGINEERING ANALYSIS HAS BEEN CLOSED.

From all the research I have done on my vehicle, it has the Takata airbag inflators that uses phase‑stabilized ammonium nitrate without a desiccant which should have been in the Nationwide Ford vehicle recall. I am the original owner of my 2003 Mustang Mach 1 and it has never had the airbags replaced and I have never received a recall notice. I had Ford run an OASIS report on my VIN and they tell me there is no recall for my car. I told them the reports don't show data past 15 years. After all these years I thought I was safe because my car never showed it had the Takata recall, so I didn't think mine had them. Now after watching a YouTube documentary and doing research, I am now afraid to drive my car. What can be done about this?

Because of Mustangs heavy doors the latch mechanism malfunctioned and the door came open on the highway. I realize the car is old but I have read up on other complaints on mustangs. The door was fine and within the couple of hours of seeing the problem I was driving 70 on the highway. And I heard the door ding go off and something told me to grab the door. It was all I could do to get back home. Which has now led to other issues like the door sagging and the window is now messed up.

The Belt Strap will get twists along the length. The Body Pillar clip refuses free movement. This is aggrevating for a Driver in the Seat. Driver in vain pushes Power Seat back to allow the Belt to clip into Latch at the Console. Reality. The car is 22-yrs old. Owner expects indifference by the local Ford shop. Both a neighbor & the Owner had a hard time about service. What does the Owner thinks a good solution? Late Model Restoration is this Model's best parts hope. A indy-body shop near the home of the car a repair alternative. Owner is [XXX] in a [XXX] & uses the Car as a Daily Driver. May be able to upload images of the car.

Date of incident....sometime over night 1/27/24. Vehicle FIRE I believe started in electrical components. Happened overnight while PARKED in front of home in parking lot Melted left side of dash (all odometer area) and center console where AC controls and radio are. Shattered front windshield which was black with soot, as well as the plastic frame around front area of convertible top. Fire has somehow extinguished itself. Whole interior car full of soot. I had actually used my key FOB to enter my car at which time I noticed what had happened & all the damage. I immediately disconnected my battery. The engine did not look damaged. The fire seemed to have stayed behind firewall. My insurance company TOTALED my car out due to the fact of it being an ELECTRICAL CAUSE TO FIRE & even if it could've been repaired, was told parts (dash, odometer area which was COMPLETELY melted) were obsolete. Regardless, the car now has posed a serious DANGER. I have photos & totaled decision by insurance company information, but have been unable to upload on your site. I believe you should REALLY SEE THE PICTURES. After incident, I searched to see if there had been any recalls. I found a couple incidents of this happening to others with their 2003 MUSTANGS & am wondering why this had never been investigated. If I had known about a problem of electrical fires, this car would NOT have been purchased in 2017. I don't understand why this problem wasn't researched. It could've been so much worse as I had a FULL TANK OF GAS.
