Finally, some good news for General Motors. After a month that started off with a horrid sales report, another big restructuring, a slumping stock price and a retreat in the truck business, the company posted good results in J.D. Power’s Initial Quality Study. Buick, Pontiac, Chevrolet and Cadillac all finished in the top 16 and above the industry average of 118 problems per 100 vehicles. Best of all, its new hot-selling family sedan, the Chevy Malibu, was the best in class for quality, beating even the Toyota Camry and Honda Accord. Those two big sellers didn’t even finish in the top three. The Mitsubishi Galant and Ford Fusion took second and third, respectively. GM needs more car buyers to read that news.
