The recall issued the past week affects certain 2005-2006 models with painted roofs. The adhesive between the roof panel and magnesium frame may separate, GM spokesperson Alan Adler told The Detroit News.
The Corvette's hard top weighs between 2.27kg and 4.54kg. If there is a complete separation, the roof panel may detach from the vehicle and it could strike another vehicle.
"You do not want to hit a 10-pound object at 70 miles per hour," Adler said.
The National Highway Traffic Safety Administration has received 21 complaints from owners of the sports car. But no one has been injured or killed as a result of the glitch, Adler said.
Corvette owners affected by the recall can get a free inspection and repair, if needed, at their local dealership.
