Air bags

“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.”

Seat belts

22 reports1 crash
“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…”

Structure

8 reports1 crash
“PAINT STARTED TO PEEL IN THE FRONT CENTER OF THE ROOF, A SMALL SPOT. I THOUGHT A STONE OR ROCK HIT IT. THEN AROUND THE SIDES OF THE BACK WINDSHIELD. THIS SPRING THE HOOD STARTED TO PEEL ALSO. FIRST IN ONE SPOT THEN IN MULTIPLE SPOTS. IT STARTS BY A BUBBLE, THEN IT POPS AND PEELS OFF IN CHIPS, WHICH STICK TO THE WINDSHIELD AT TIMES. THEN IT STARTS TO PEEL OFF IN BIG PIECES. AT ALL TIMES IT PEELS DOWN TO THE BARE METAL. IT DEFINITELY APPEARS THAT THE AFFECTED AREAS(PARTS) ARE NOT PRIMED. WHEN DRIVING YOU CAN SEE THE PAINT START TO LIFT OFF AND LET GO. THIS PROBLEM SEEMS IT WILL NOT STOP UNTIL THE WHOLE HOOD AND ROOF ARE BARE. SEAT BELT LIGHT DOES NOT GO OFF WHEN BUCKLED. YOU CAN ATTEMPT TO BUCKLE AND UNBUCKLE MULTIPLE TIMES IT WORKS AND DOES NOT WORK. SOME DAYS THERE IS NO PROBLEM AND OTHER DAYS IT IS AN ISSUE. *TR”
