GM said a modification to the shield will keep liquids from becoming trapped in the engine compartment where they could start a fire. The recall affects 2011-12 model year vehicles built from September 2010 to May 2012 at Lordstown, Ohio.
Separately, GM will inspect all welds in the rear compartment of the recalled vehicles to make sure they were properly applied. The company said there could be a problem in about 249 cars that may affect the fuel tank strap secondary brackets attachment to the floor and a sub-assembly to the rear floor pan.
GM said it is unaware of any crashes or injuries related to either problem. Only vehicles sold in the United States and Canada, and a few hundred exported to Israel, are affected.
The National Highway Traffic Safety Administration began investigating the issue following two engine compartment fires, GM said.
GM said the modification will take about 30 minutes and be performed at Chevrolet dealerships free of charge. Owners will begin receiving letters July 11.
