WASHINGTON — General Motors is recalling 3,196 2011-'14 Chevrolet Express and GMC Savana compressed natural gas vehicles because they may leak natural gas, according to the National Highway Traffic Safety Administration.
"The affected vehicles may leak natural gas from the CNG high-pressure regulator," NHTSA said in its summary of the problem. "A natural gas leak in the presence of an ignition source increases the risk of a fire or explosion."
If a leak is suspected, the customer should not start the engine or drive the vehicle.
"The customer should immediately have the vehicle towed, inspected and repaired," GM told federal safety regulators.
GM said it is not aware of any fires, crashes or injuries linked to the recall.
The affected Express CNG vans were built from September 10, 2010 to April 28, 2014. The affected GMC Savana CNG vans were built from May 23, 2011 to April 21, 2014.
GM said its analysis "revealed a high incidence of leaking regulators associated with a replacement of the solenoid" under a May 15, 2013 recall.
By the end of May 2014, GM had identified 30 cases of regulator leaks.
Dealers will replace the high-pressure regulator. A date has not been set for the recall, but GM spokesman Alan Adler told Edmunds on Thursday that "parts are on order and customers will be notified by letter when they are available."
He added that there are an additional 13 recalled vehicles in Canada.
Edmunds says: If you own one of these vehicles and notice a problem, don't drive it and contact your dealer immediately.
