Burning of terminal on brake light switch wiring. Brake lights left on.
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.
Flooded salvage title not listed.
Brake pedal switch harness connector deformed resulting in inoperative brake lights. Wires no longer fit within plastic connector.
