General Motors Corp. announced on Tuesday that it is recalling more than 300,000 trucks and sport utility vehicles because of problems with the turn signal on some vehicles.

GM said that the recall involves the 2003-2004 model years of the Chevrolet TrailBlazer, the GMC Envoy, the Isuzu Ascender and the Oldsmobile Bravada. It also includes the 2004 Buick Rainier. Most of the vehicles were sold in the United States.

The company said the problem raised safety concerns that a driver might not be able to signal his or her intention to turn, change lanes or warn others that the vehicle was impaired along the side of the road.

However, the largest automaker said that there have been no crashes or injuries related to the defect.
