After driving in the snow for the 1st time with my new Malibu, the snow buildup behind the tires froze overnight. The next morning when driving to work, the chunk broke off taking some of the platic body panel with it. As matter of fact this has happened on both sides of the car. Has anyone else had this problem? Is it a Chevy defect worthy of recall? I would think that the panels should not break off within the first 10,000 miles......Anyone?
