Both air bag lights have stayed lighted four months apart. Replacement was a complete (using Ford Motor Co parts) unit on driver-side in May 2014. Now(Sept 9,2014) the passenger side unit needs replacement at a cost of $700 for each side. The state of Virginia inspection process requires replacement for the vehicle to pass. I'm told the air bag is in-operative when the light is on this a safety issue.

My 2005 Mercury Grand Marquis airbag light is on. Dealership claims the airbags will not deploy due to a malfunctioning seatbelt pretensioner. Repair/replacement will cost $1800 to do both passenger and driver. Car only has 29,250 miles on it. I have found where this seems to be an ongoing problem with this model. Also, saw where this issue has caused airbags not to deploy in a collision. Some have reported the problem reoccurring after repair. This is a bad design by Mercury and a huge safety concern that should have been issued a recall!

The seat belt warning air bag light came on and won't go off. It happen back in Aug 2011 at 40,598 miles now two years later at 53,631 same probelm again. I filed a complaint then and now once again, when are you people going to make Ford fix these cars right. If you look at all the complaints filed concerning the seat belt probelm it would seem to me that you are doing absoulety nothing except letting these car manufactures give us consumer a bunch of bs and charge us and arm and leg to fix some thing that shouldn't be failing that soon. I mean come on in 13,000 miles and it fails again. It will cost me another $450 to fix the same probelm and if I don't the air bag system will not work so where does that leave me"?"

I own a 2005 Mercury Grand Marquis. The air bag warning light illuminated once the engine was started and remained on. The vehicle was taken to the local Ford dealer service department for diagnosis and I was informed that the driver's side seatbelt pretensioner would need to be replaced at a cost of $501 in addition to the $103 charged for diagnosis. The vehicle has not yet been repaired. I will inform the manufacturer. I observe from other websites/reports what I believe may be a pattern of premature failure of Grand Marquis seatbelt pretensioners especially in the 2005 model year. The failure mileage was 127,084 and the current mileage was 127,201.

Approximately 2 months ago, my driver's side front seat belt failed to lock. I could not get it to lock properly and, as a result, I had to drive without a seat belt until the dealer was able to get delivery on a replacement unit.
