Porsche Named Most Dependable in Study

German Sports Car Brand Earns Top Spot in J.D. Power and Associates Review

(AP)  Porsche shot to the top of a closely watched study of long-term vehicle dependability, overtaking U.S. and Japanese rivals, J.D. Power and Associates said Thursday.

The German sports car brand took the No. 1 spot in the annual study, which gave it ninth place last year. Lincoln came in second, while Buick and Lexus tied for third. Mercury and Toyota rounded out the top five.

The annual study measures problems experienced by the original owners of vehicles after three years. In last year's study, Buick and Jaguar tied for fewest problems, but both brands lost ground to rivals this year.

Toyota, whose reputation has come under scrutiny in the face of massive recalls, fell two spots from its third-place standing last year. While average vehicle quality across the industry improved from last year's survey, Toyota's quality score fell slightly.

However, the Japanese nameplate still swept four segment awards, more than any other brand. Japanese rival Honda took three segment awards, while Ford Motor Co.'s Lincoln brand took two awards.

Fixed Toyota Complaints Hit Triple Digits

The industry average was 155 problems per 100 vehicles, J.D. Power said, or less than two problems per vehicle. That's a decline from 167 problems per 100 vehicles last year.

"The improvements in long-term dependability and component replacement rates are good news for both consumers and manufacturers," said David Sargent, vice president of global vehicle research for J.D. Power, in a statement.

J.D. Power's 2010 dependability study surveyed more than 52,000 original owners of 2007 model-year vehicles between October and December 2009. The results are watched closely by automakers and are often used in advertising. Owners' opinion of a car after three years can be a major influence on their opinion to buy that brand again.

The firm also releases an initial quality study, which measures problems in the first 90 days of ownership. That study usually comes out in June.
