General Motors has told dealers in the U.S. and Canada to stop selling 2013 and 2014 Chevrolet Cruzes because of a potential defect in the air bag.
"Certain vehicles may be equipped with a suspect driver's air bag inflator module that may have been assembled with an incorrect part," GM spokesmen Jim Cain said in a statement.
The order affects all Cruze vehicles until it can determined which one have the bad part.
The stop sale order is the latest setback for GM which has already recalled more vehicles than in any other year in its history. GM has been under intense scrutiny since February for a defective ignition switch in older model Chevrolet Cobalt, Pontiac 6, Saturn Ion and Saturn Sky cars.
So far, GM's sales have continued to climb, but the suspension of sales will impact sales of Cruze -- the best-selling Chevy car -- in the last week of June.
GM declined to identify the supplier of the air bags.
"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," Cain said.
