Special Technical Campaign. The National Highway Traffic Safety Administration (NHTSA) has urged vehicle manufacturers to conduct an investigation into air bags which may not deploy correctly. BMW is cooperating with this request. Takata is a supplier of air bags to several automotive manufacturers. They have informed NHTSA of a small number of cases of improperly deploying air bags in a few specific areas of the US. None of the reported cases involve any BMW vehicles. No determination has been made by BMW and Takata that a safety issue exists.This program involves the driver and front passenger air bag system. Specifically, the air bag system may have been manufactured with an inflator that was not produced to specification. After long-term exposure in high absolute humidity environments, in a crash in which air bag system deployment occurs, the air bag system housing may rupture. To assist Takata with their determination, BMW will be collecting air bags from a limited number of customer vehicles. Once the affected vehicle population has been determined, owners of affected vehicles will be notified by letter to visit their authorized BMW center to have their air bag(s) replaced. Additional information will be provided at that time. A press release from NHTSA on this topic is expected to be issued on Monday, June 23, 2014.
