DETROIT -- A study by J.D. Power and Associates finds that sales of mid-sized SUVs are slowing as a pullback in incentives does little to offset rising gas prices, according to Reuters. Out of the 26 segments tracked in the study, mid-sized SUVs had the second highest days-to-turn rate in May, with vehicles sitting on dealership lots an average of 73 days or twice as long as vehicles in the basic compact car segment. The study also points out fewer owners returning to the segment when they purchase or lease their next vehicle, with 24.5 percent of mid-sized SUV owners trading vehicles in the same segment in May, down from 29.2 percent in January. U.S. automakers such as General Motors and Ford Motor Co. have been hurt by declines in the segment, which have been forecast for quite some time due to rising fuel costs.
