Chevrolet cars are seen at a GM dealership in Miami in this file photo

Chevrolet cars are seen at a GM dealership in Miami, Florida in this file photo from August 12, 2010. General Motors dealers are frustrated the automaker is not telling them more about the recall of 1.6 million cars after a string of deadly accidents, and many say a delay of several weeks before a fix is ready is bad for business.
