Some tanks used to convert vehicles to run on compressed natural gas may be prone to low-level leaks, one of Oklahoma's leading conversion companies said Friday.

Gov. Mary Fallin's CNG-fueled Cadillac Escalade is one of the vehicles subject to the safety notice issued by manufacturer Hexagon Lincoln.

Okarche-based OEM Systems began notifying customers, including Oklahoma officials, of the safety notice on Friday afternoon.

President Lisha Oshman said there have not been any incidents involving the Hexagon Lincoln tanks, which the company has used in most of its conversions.

Which vehicles

are affected?

Only a small number of tanks are subject to the safety notice, officials said.

Oshman said Hexagon Lincoln has recommended parking vehicles with suspect tanks outdoors so any leaked CNG can dissipate into the air.

Tanks subject to the safety notice will be replaced at the manufacturer's expense.

Fallin, a vocal CNG advocate, said she appreciates the efforts by OEM Systems and sister company Carter Chevrolet to fix the problem.

“This is a minor inconvenience,” spokesman Alex Weintz said. “She is happy to have made the switch to CNG. The transition is helping save taxpayer dollars on fuel costs while supporting an Oklahoma-produced fuel source.”
