Drive one of these 7 Hondas or Acuras? Stop now. Seriously, stop.

The Takata airbag recall just became deadly serious.

The National Highway Traffic Safety Administration (NHTSA) released new laboratory testing results Thursday morning that show the Takata airbags in seven Honda and Acura brand vehicles have a 50% chance of rupture. (This stands in contrast to faulty Takata airbags in other models, which have a 1% chance of rupture.)

When the airbag inflators do rupture in the Honda and Acura vehicles in question, they can cause serious injury and even fatality.

Accordingly, the NHTSA is calling on owners of these models to stop driving them immediately until the airbags can be replaced as a part of the ongoing recall.

The models that fall under this increased warning include: 2001-2002 Honda Civic, 2001-2002 Honda Accord, 2002-2003 Acura TL, 2002 Honda CR-V, 2002 Honda Odyssey, 2003 Acura CL and 2003 Honda Pilot.

The 2002 Honda Civic EX Sedan is one of seven models at risk for airbag rupture.

“The air bag inflators in this particular group of vehicles pose a grave danger to drivers and passengers that must be fixed right away,” NHTSA Administrator Mark Rosekind said. "Drivers should visit SaferCar.gov or contact their local dealer to check whether their vehicle is affected. If it is, they should have the vehicle repaired immediately for free at an authorized dealer. We commend Honda for taking additional actions to get these vehicles repaired.”

Inflator ruptures are more likely in high-humidity areas of the country, particularly Florida, Texas and other parts of the Gulf Coast. When the inflators rupture, they can propel metal shrapnel into the faces and bodies of drivers and passengers.

If your Honda or Acura is a part of this recall and hasn't yet been fixed, get it to your dealer right away. Don't drive it. Call a tow truck.
