The short answer

NHTSA received STRUCTURAL COMPOSITES’s report on May 9, 1995. Copied from NHTSA on Oct 24, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

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.

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.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
  • How many have been returned or fixed isn’t in the notice.
