NHTSA investigating possible Jeep air bag problem

WASHINGTON (AP) - Federal regulators are investigating reports that the air bags on some Jeep Liberty sport utility vehicles are suddenly going off without a crash happening.

The National Highway Traffic Safety Administration says on its website that in four of seven confirmed cases, the front driver-side air bag went off, while in three, both the driver- and passenger-side air bags deployed.

The investigation involves an estimated 387,356 vehicles made during the 2002 and 2003 model years. Five of the seven reports involved injuries.

Some owners said they saw the air bag light come on, or intermittently come on, before the air bags went off.
