Recalls for the 2003 Buick LeSabre: 1
Certain passenger, Mini vans, and sport utility vehicles have an air bag inflator on the driver's side that could fracture at a weld during a deployment. Pieces of the inflator could strike and injure vehicle occupants and the air bag cushion would not inflate fully, reducing the capability of the bag to protect the driver.
