The airbag warning light comes on intermittently. According to my online research this seems to be very common on the 2008 Lacrosse.
Red airbag warning light appears intermittently. Dealer identified a problem with the sensor in the passenger seat and replaced the part. The same problem has since reappeared. The light will turn off when the passenger slides the seat back and forth or unfastens and refastens the seat belt. This problem can occur at any time and does not require the vehicle to be in motion nor the presence of a passenger. The problem is more likely to occur in warmer weather.
The airbag indicator warning light comes on intermittently while driving my 2008 Buick Lacrosse. This car has only 23,000 miles on it. The failure happens every time I drive my car with or without someone in the front passenger seat. This exposes the driver and passenger to danger as no airbag protection is afforded to them when the light is on. I brought the car to the dealer for diagnosis, they said a part may be needed that costs about $1,000 to replace. This needs to be recalled because it is a safety issue that many Buicks have, and the replacement costs should be covered by general motors, not the customer. Apparently, I am not the only one to experience this issue. Here is a link to the carcomplaints. Com website where many others have shared their experiences with this problem. . Read more...

The passenger air bag warning light will come on when I'm driving and no one is even sitting in the passenger seat. Anything sitting on the seat weighs much less than the 80 lbs specified in the manual. Sometimes the light will come on when I have a passenger sitting there, indicating that the air bags are off - when they should be on!!! there is no event that consistently triggers the light coming on. I might be turning or slowing down or just driving down a straight road. Sometimes, the light will stay on for a couple of minutes, and sometimes it will stay on for more than ten minutes. I've taken my car to the dealer five times in the four years I've owned the car, and the first four times, the dealer fixed it at no charge. This time, the dealer says it "has gone all the way down to the passenger detection module and it will cost you $1250 to fix it. " a passenger detection modules sounds rather important to me, and very much a safety issue, but the service manager said that if there's no recall, it's customer pay. With the number of complaints made on this site for this identical issue, I'd say it's highly likely that there are many more cars with the same problem, but their owners just don't know about this site. Is it necessary for a certain number of complaints before an investigation is made? I guess my husband will just have to trust his luck - he's the one generally sitting in the passenger seat!!.
