Defect investigations
Steering Column Shaft Obstruction
On July 7, 2014 the Office of Defects Investigation (ODI) opened a preliminary evaluation based on five complaints (VOQs) alleging incidents ofinterference between dislodged exhaust manifold heat shields and the lower steering shaft/knuckle, including one alleging the interference resulted in a crash on a highway entrance ramp. Since opening this investigation, ODI has received four additional owner complaints.One indicated that the shield was removed before binding could occur.The other three occurred at low speed and produced some momentary steering binding that was overcome by the driver when additional steering effort was applied.Once the shield was repaired or removed, the steering returned to normal.The single incident ODI identified as a possible crash (VOQ No. 10578715) related to this condition could not be verified and the description of the crash in the complaint was not supported by the police accident report.No additional crash allegations have been identified related to the alleged defect condition.Information provided by Ford in its September 10, 2014 response to ODI's information request letter identified 10 additional incidents resulting in a low rate of 1.6 incidents per 100,000 vehicles sold in vehicles ranging from 7 to 11 years in service.Six of these incidents were reported by a single source, a state police fleet that corrected the problems in March 2011 and has not reported any additional failures since.Ford also reported 5 warranty claims, but these incidents occurred at very low mileages and appeared to be caused by loose or missing heat shield attachment hardware rather than the corrosion condition that was the cause of the more recent incidents and the focus of this investigation.This investigation is closed. The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist. The Agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.The following VOQs are associated with this investigation:10643753, 10615584, 10611362, 10610451, 10578715, 10479681, 10471833, 10317493.

What 2006 Mercury Grand Marquis owners say
Most recent owner complaints, unedited.
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.

Driver and Passenger side seat belt pretensioners failed and have resulted in airbags being inoperable.
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!
