Vehicles Affected: More than 3,000 GM full-size cargo vans from the 2011-14 model years that run on compressed natural gas, including Chevrolet Express vans manufactured between Sept. 10, 2010, and April 28, 2014, and GMC Savana CNG vans manufactured between May 23, 2011, and April 21, 2014
The Problem: The vans may leak natural gas from the CNG high-pressure regulator, which in the presence of an ignition source increases the risk of a fire or an explosion.
The Fix: GM will notify owners, and dealers will replace the high-pressure regulator for free. The automaker has not yet announced a notification schedule.
What Owners Should Do: Owners can call Chevrolet at 800-222-1020 or GMC at 800-462-8782 for more info. They can also call the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or go to www.safercar.gov.
