In a letter notifying its dealers, the company said the dealers can not order 2010 Malibu hybrids because of a glut of 2009 models.
The four-cylinder model with a six-speed transmission debuted last summer and it was the first of its kind for the American auto industry.
In March 2008, then-CEO Rick Wagoner announced plans for the next-generation hybrid system in 2010 and said GM would make it available in a wide range of cars and trucks around the world.
