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.
Tl* the contact owned a 2006 Mercury Grand Marquis. While driving at an unknown speed with the cruise control activated, the vehicle suddenly accelerated. The rear brakes locked when the failure occurred. The contact was unable to stop the vehicle and crashed into a tree. The air bags failed to deploy. The front seat passenger was injured and received medical attention. The vehicle was destroyed. A police report was filed. The VIN was not available. The failure mileage was 38,000.
In feb, 2014, I originally had a minor crash when another driver was cited for reckless driving. His insurance paid for my damage. No airbags were deployed on either me, the driver, or my mother, the passenger. We were belted in. Recently, on September 7th, 2015, the airbag warning light and chimes came on when I started the vehicle. The light continues to come on, the chime rings in 3 sets of 5 periodically. The dealer that fixed the original damage, alan jay, ran a $55 diagnostic and stated the passenger seat belt pretensioner was open, and that this could have only occurred in an accident. I asked why the system did not respond the 1 1/2 years earlier when the accident occurred? …
Air bag light comes on and blinks code 3 3 then dings an alarm 5 dings x 5 times every 30 minutes, light stays on. I understand code 33 or 34 are seat belt pretentioners that are known to fail on mid 2000's Ford vehicles. Mine is 2006 Grand Marquis. This appears to be a defect in materials causing a saftey concern for myself and passengers. The air bag system is disabled until repaired and the repair is very expensive. The vehicle has not been in an accident and it has been diagnosed as a driver side pretentioner high resistance failure. The mechanic suggested they replace both driver and passenger side since the passenger side will most likely also fail soon according to his experiance. This should be recalled to have pretensioners replaced since it is a known defect and safety hazard caused by Ford parts.
On September 9, 2015 I purchased a used 2006 Mercury Grand Marquis ls. I was informed that the airbag light was on. I subsequently found that there had been some minor damage to the lower front of the vehicle, not resulting in airbag deployment. In researching the problem and to determine if there had been an airbag recall by the NHTSA, I found that there had been 57 registered complaints on the repair pal website and that a complaint had also been filed with the NHTSA.for this problem and that the problem was a result of defective seat-belt assemblies. There should be a safety recall issued for this problem as it effects the proper functionality of the restraint system in the event of a collision.

Start engine, air bag light on dash illuminates, beep alarm sounds for a series of five beeps followed by 1 second of silence, and repeats for five repetitions of the same. Light remains on and after 30 minutes of driving on road operation, the alarm repeats for 5 repetitions as before. This continues as long as the engine is operated without turning off. When shut off and restarted, the alarm starts all over for the series of 5 beeps in 5 repetitions. My dealer says this is not a safety issue and wants over $800.00 for a new computer module. I have no way to document complaint or dealer response.

Air bag light started blinking, same sequence repeated five times after wards it stayed on. After a minute or so a warning beep sounded. The beeps were in a sequence of 5 beeps which repeated five times then repeated again every half hour while driving.. Mechanic replaced the whole drivers side seat belt assembly - $800.00.
