Hummer spokesman Nick Richards says a device on the hood called a hood louver (LOO-ver) can come loose and possibly detach while driving. The device helped to cool the engine on older Hummer models but is decorative on the H3.
Richards says the repair involves applying an adhesive to refasten the louver to the hood. He says there have been two complaints of the problem in the U.S. and three in Japan.
GM is in the process of shutting down Hummer after an attempt to sell the brand to a Chinese buyer fell through earlier this year.
