Vehicles altered by pas, Inc. Have compressed natural gas fuel tanks that can develop stress corrosion, which crack the E-glass wrapping. This stress corrosion cracking can lead to tank ruptures.
GM is offering to exchange these vehicles with a comparably equipped 1994 gasoline 1/2 or 3/4 ton GM pickup. If the owner chooses not to exchange the natural gas vehicle, GM will repurchase the vehicle.
