I have a 2008 Buick Lacrosse cxl which I purchased 04/29/2008. At about 3,000 miles I noticed the passenger air bag light would come on intermittently showing the bag was off even though my wife was in the seat and buckled up. I took the unit into the local dealer and the service advisor told they couldn't check for a code unless the "off" light was showing when someone was in the seat. Later the indicator lamp started coming on and would stay on (showing the air bag was off) for miles. I returned to the dealer I purchased the car from and they checked all connectors and pins. It did not malfunction when they test drove the vehicle but the malfunction returned on the way home. This dealer has rechecked the vehicle two times to no avail, the light still comes on. I have found if I have my wife move the seat forward and/or backward the light will go of for a while, (the time varies with the road conditions e.g. rough, smooth, straight, curvy and so forth). I found another instance on line where a 2009 Lacrosse had the same problem as mine. A fix was not provided in their investigation of the vehicle. Buick doesn't list any technical bulletins pertaining to this malfunction. This is a very dis-concerning issue any time we drive and I suppose it is a safety issue also.
