General Motors says it is halting delivery of all 2013-14 Chevrolet Cruze sedans in North America because of a potential problem with the airbags.

The U.S. automaker tells CityNews in a statement that it has directed all “Chevrolet dealers in the United States and Canada to stop delivery of new and used 2013-2014 Chevrolet Cruze vehicles until further notice.”

GM says some airbags on the driver’s side may have been assembled with an incorrect part.

“We are working diligently with the supplier of the defective part to identify specific vehicles affected and expect to resume deliveries by the end of this week once those vehicles are identified,” the company said.

GM says so far it has identified 33,000 vehicles that may have the glitch.
