General Motors Thursday lifted a do-not-sell order to dealers on its new Chevy Aveo. Last week, the automaker issued the order following five crashes that were reported from the field in January. The automaker investigated to see if the crashes could have been caused by a common mechanical problem. GM spokesman Jim Schell said neither a defect nor common cause was discovered. GM is being extra careful about quality these days as it tried to close the quality gap with industry leaders Toyota and Honda, and especially tries to close the perception gap that its quality lags its Asian rivals by miles instead of inches. The Aveo is a rebadged Daewoo, built in South Korea. The car, which comes in sedan and hatchback, began shipping to dealers in early January. Priced from about $10,000 to $13,500, the car is meant to cover the entry-level market filled recently only by deeply discounted Cavaliers and Pontiac Sunfires. -Jim Burt
