The defect
Upon exposure to impurities in the natural gas fuel in cold weather, an internal o-ring on these devices can blister during decompression after "fast-fill" refueling resulting in seal leakage.
The risk
Internal damage to the o-ring seal could cause a release of CNG. If CNG were released to the environment and an ignition source were present, a fire could occur.
The remedy
Dealers will replace recalled units with new devices that are not susceptible to o-ring damage from non-methane components of the gas supply when the devices are developed.
