Honda is told to do more to fix customers' faulty airbags.

FOX's Chris Foster reports: 

Tests show that inflators in 313,000 older Hondas and Acuras have up to a 50-50 chance of rupturing and shooting shrapnel at the driver in a crash.

It's reported that only 13,000 of those cars have been fixed since June and the head of the National Highway Traffic Safety Administration says it's ultimately on the car company, not the airbag supplier Takata, to take care of this.

Mark Rosekind says Honda has been spoken to about hiring private investigators to track down owners or sending service trucks into neighborhoods to fix cars on the spot.
