Federal regulators have stepped up their investigation into Toledo built Jeep Liberty air bags.
50 people have now reported they were hurt when the air bags inflated by surprise, without a crash.
The National Highway Traffic Safety Administration has been investigating 2002 and 2003 model years of the vehicle since September.
Nearly 387,000 Jeep Libertys built at the Toledo North Assembly Complex are under investigation.
Safety regulators say the air bag computer may fail due to an electrical voltage spike.
Chrysler says no incidents have been reported in vehicles made after March 13, 2003.
