On certain natural gas vehicles, in the rare circumstance that a flame from a vehicle interior fire becomes locally directed at the natural gas tank located immediately behind the rear seat, the locally directed flame could damage the fiberglass wrap on the tank thereby reducing the hoop strength of the tank. If the hoop strength is significantly compromised, the tank could rupture and potentially result in personal injury. Correction: Dealer will install an insulator behind the seat back.
On some natural gas powered vehicles, a "T" fitting that connects fuel tanks three and four may develop a leak when the ignition switch is in the ON position. The leak can easily be heard and will stop when the ignition key is turned to the OFF position. There is a potential for fire and serious injury if there is a leak in the presence of an ignition source while the key is in the ON position. Correction: The dealer will replace the "T" fitting.
