The passenger airbag light started coming on and going off intermittently. After several weeks of this, it was on every time the car is driven. Testing by an ASE certified mechanic revealed that the permanent light results in no front seat airbags. The failed part is the seat presence sensor. The part is - and hasn't been for quite a while - manufactured by GM. Aftermarket parts are costly and the installation cost is in the hundreds of dollars. Research indicates that this is a well-known and long reported issue. Why not a recall years ago? Other than brakes and steering, could there be any more unsafe components than those affecting airbags? The only remedy other than continuously replacing the faulty part, is a bypass module. If it functions correctly, the airbag will deploy regardless of passenger weight. This puts any child or underweight rider in danger. And, of course, considering the expense, many owners will do nothing with possibly grave consequences. I think you "dropped the ball" big time on this one!

Airbag warning light by model year
What owners say
The air bag light on the dashboard is on all the time.It is available for inspection at any time. I do not know if the bag will go off at any time or does it mean that it won't go off on impact. I am nervous about having someone for a passenger. I have informed the dealership of the problem and they did confirmed the problem, it has not been inspected by the manufacturer or others. The light came on the day after I bought the car from the dealership and it has been on every cents.
Abou 50,xxx miles the service airbag light in the dash began to illuminate intermittently. It would occur once a month or so. The dealer wanted $1200 to replace the ab control module. For the next 46,xxx miles it has been that way until a few days ago. Now the airbag light is on continually, meaning the airbags are inoperative. Seems like a safety issue to me!
My 2009 lacrosse will intermittently display the air bag indicator. I noticed this while driving the car around town and there is no passenger in the front seat. It will either stay on for a couple of days and then disappear or will just be on for short periods of time. When I took it to the dealer they stated it was a sensor module and would be approximately $1300 to replace. As of this date, I have not had it repaired. The vehicle only has approximately 24,000 miles. I checked to see if there might be any recalls for this issue and there were none. But in checking online, this appears to be an issue with many buicks especially the 2008. To me this appears to be a safety issue that should be addressed.
Seatbelt light came on dash on; no airbag light also on for passenger side. First time it happened someone exited passenger seat while car was in park. Intermittent chime whether seat belt was in use or not; whether someone was in passenger seat or not. That has since ceased to happen. Dealer states dash light on also means no airbag for driver side. Fix is over $1500. Have read many other similar complaints all over america with other buick vehicles and years. How is this not a recall/safety issue?

Air bag indicator light on passenger side is off 50% of time when carrying a passenger electric automatic door locks fail to operate on driver's side and on occasions when they work you have to manually unlock the doors
The air bag light comes on intermittently. I took it in for service, and was told it would be $1300 to replace the passenger presence module. I've seen other complaints online regarding this same item. I've also had issues with the automatic locks. It initially started with the passenger front door, and has now progressed to all the doors. The price I was given to repair this was $1600. Again, I've seen numerous online complaints concerning this item. This is my 3rd buick, and I do not intend to buy another one. It seems once the warranty expires, several costly repairs are incurred.
I am a used car dealer and sell a lot of buick lacrosses and have seen at least 7 bad pass. Seat switches in the seat very expensive to fix and should be recalled by gm,this will turn the air bag light on
