“5/9/2021 The SRS dashboard light came on with a bell warning. Bell quits after a short time but the light stays on solid. When turning ignition on, light and bell comes on, blinks 3 times, does this 6 times and then stays on solid. When driving hear bell for 5 times, this repeats later for a total of 5 times. After turning the ignition switch on/off I hear a sound from under the driver or passenger seat. The passenger side air bag light does light. I bought this car new.”
“AS I WAS DRIVING. 35MPH MY FRONT WHEEL ON THE DRIVER SIDE HAD SNAPPED OFF CAUSING MY VEHICLE TO CRASH INTO A PARKED VEHICLE. LONG STORY SHORT. I'M GOING THRU A FINANCIAL CRISIS.

TRANSPORTATION IS ESSENTIAL TO ME. PLEASE I NEED HELP. *TR”
“Around 12 years ago, when my 2006 Marquis, which I purchased brand new, had only approximately 40,000 miles on it, the seatbelt-airbag system warning appeared on the instrument panel and a warning bell sound went off with a 3 beep then 2 beeps/ring tone that would sound whenever the vehicle was started for the next two minutes of driving. It would then stop but the yellow warning icon stays on. On a trip, while driving, it will do this every hour or so or 60 miles of driving, and has done this ever since. (I'm retired and drive very little, my vehicle as of today (5-13-2022) has only 54,462 actual miles on it.) I did some research when it first occurred and learned that the 3 - 2 beeps is a "code 32, seat belt pre-tensioner failure warning and will need immediate service and replacement." So I then called Ford and explained it as above. They told me that it is not their problem and are not acknowledging any responsibility and it will be up to me to see a dealer, which I did. I was told that it would require replacement of both my seat front seat belts, and possibly more including airbag components to the tune of several thousand dollars! I asked them, as I did…”
