Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.

NHTSA ID 11541736 · filed Aug 30, 2023

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 Ford: As I've had many Ford vehicles, personal and company, several of which I've driven over 200K miles, without ever having a seat belt or airbag component failure, how is this MY problem and not Ford's, especially after only 40K miles? I had asked Ford these two most important questions: 1- "What did I do to CAUSE THIS FAILURE?" and 2- "What could I HAVE DONE TO PREVENT IT?" They refused to answer and only told me that I need to take it to a dealer to have it repaired. I have not pursued it as I didn't have the thousands of dollars the dealer wanted to charge me. This is wrong as it is part of Ford's refusal to acknowledge the faulty components in their seat belt/airbag systems, which has been putting my life at risk ever since their components' failure and Ford needs to be held responsible!

WHEN PARKING A NEWLY ACQUIRED USED 2006 MERCURY GRAND MARQUIS AT IDLE SPEED IN A LOCAL SHOPPING CENTER, THE ENGINE ACCELERATED AND THE HARDER I PRESSED THE BRAKE THE FASTER THE ENGINE RAN. TO THE EXTENT THE TRACTION CONTROL ACTIVATED AND THE WHEELS SPUN IN PLACE. THE ONLY WAY I PREVENTED CRASHING INTO THREE PARKED WAS TO SHIFT THE TRANSMISSION INTO NEUTRAL WITH THE ENGINE RACING. WHAT APPARENTLY HAPPENED WAS MY FOOT WAS NOT CENTERED ON THE BRAKE PEDAL AND THE PEDAL TRAVELED TO THE POINT WHERE I WAS ALSO PRESSING ON THE ACCELERATOR. EVIDENTLY THE TRAVEL DISTANCE OF THE BRAKE PEDAL WAS SO LONG I PRESSED ON THE ACCELERATOR PEDAL AT THE SAME TIME. I TOOK THE CAR TO A MERCURY DEALER AND WAS TOLD THIS WAS A COMMON PROBLEM, BUT HE COULD NOT CORRECT IT BECAUSE THE BRAKE AND ACCELERATOR PEDALS WERE OPERATING AS DESIGNED. THE DEALERS TECHNICIAN REPORTED THAT MY COMPLAINT WAS THAT THE PEDALS SEEMED TO CLOSE TOGETHER. THIS MAY BE TRUE, BUT THE PROBLEM IN MY MIND IS THE TRAVEL DISTANCE OF THE BRAKE PEDAL. I WAS ALSO TOLD FORD HAS NOT AS YET ISSUED A SOLUTION TO THIS SAFETY PROBLEM. *TR
