Valve Problem Prompts Recall of 2011 and 2012 Vehicles

The Vehicle Production Group is recalling 435 of its compressed natural gas-fueled MV-1 vehicles to install a secondary pressure relief device to prevent fuel leaks.

The Vehicle Production Group is recalling 435 of its CNG-fueled MV-1 vehicles to install a secondary PRD to prevent methane leaks.

“The pressure relief plug for the CNG storage tank may be incorrectly assembled,” the National Highway Traffic Safety Administration says in a summary of the issue (NHTSA campaign 12V468000). “If the plug is incorrectly assembled, it may inadvertently discharge the CNG. A CNG leak in the presence of an ignition source may ignite and result in a vehicle fire.”

Accordingly, NHTSA says, VPG will notify owners and dealers of the problem, “and dealers will install a secondary pressure relief device on each vehicle to prevent leaking, free of charge.”

VPG Has Moved to Detroit

VPG reported seven incidents of inadvertent natural gas venting – four at the AM General assembly plant in Mishawaka, Ind., and three at customer sites.

VPG cited a manufacturing problem with 1705X2 valves by GFI Control Systems in its notice to NHTSA. The devices were used with Type III CNG cylinders by Worthington-SCI, says Tom McGiver of GFI.

Separately, VPG spread the word last week that it has moved its headquarters from Miami – where it will maintain a sales office – to Michigan.

“We designed and engineered the MV-1 in Metro Detroit and we plan to stay here and support the local economy,” CEO John Walsh said in a release.

Walsh characterizes VPG as America’s number four OEM, following Chrysler, Ford and GM (F&F, June 13). Detroit, he says, is “where America’s fourth automaker belongs.”

VPG said it hopes to have 150 dealers in place by the end of 2012.
