THIS COULD RESULT IN A TANK RUPTURE, EXPLOSION, AND EJECTION OF THE TANK FROM THE VEHICLE.
Honda recalled certain compressed natural gas (CNG) Civic vehicles to add insulation to the rear seat back. In the event of an interior fire, the CNG tank could become compromised due to uneven heating, preventing the pressure relief safety device from functioning as designed. If the tank heats and does not vent the contents, the tank could rupture and explode. Dealers will install the insulation to help protect the tank from uneven heating.
