General Motors has initialed a safety recall of 3,196 model year 2011-2014 Chevrolet Express and GMC Savana Vans converted to dedicated compressed natural gas operation by Impco Automotive.
“Some of these vehicles may have a CNG high pressure regulator that leaks natural gas,” GM told dealers last month. “This could cause an explosion or a fire if an ignition source is present.
“To correct this condition, dealers are to replace the regulator.”
GM and Impco began looking into the matter in March after learning from a fleet customer that a leaking regulator had been replaced on a CNG van in January.
