BMW is expanding a recall of its most popular car models to fix an air bag problem.

BMW is recalling 1.6 million 3-Series cars from model years 2000 to 2006 across the world, including 574,000 in the United States.

On Wednesday the company announced that the recall is simply a precaution because other automakers using similar systems have reported problems.

Air bag inflators in systems made by Takata Corp. can rupture which could cause the bags to not work properly, and shards could fly out, causing injury.

BMW has said that it has no reports of problems in its vehicles. Dealers will replace the passenger-side front air bags. They say they are recalling all vehicles equipped with the potentially faulty air bag systems.
