Porsche tops J.D. Power 2007 Initial Quality Study second year running

2007 IQS Ranking Highlights

Mercedes-Benz and Toyota models capture three segment awards each. Toyota models that receive awards are the 4Runner, Sequoia and Tacoma. Mercedes-Benz models that earn awards are the E-Class, SL-Class, and the S-Class. The S-Class ties with the Audi A8 (total) for having the fewest quality problems in the industry, with just 72 problems per 100 vehicles.

“Mercedes-Benz shows dramatic improvement, particularly with its newly-redesigned S-Class, which improves 63 PP100,” said Oddes. “Overall, Mercedes-Benz improves its nameplate rank by 20 positions—the greatest rank increase of any nameplate in the study. All Mercedes-Benz models in the study improved substantially, and the breadth and speed of these improvements demonstrates the Mercedes-Benz commitment to quality.”

For the second consecutive year, Porsche tops the overall nameplate rankings, averaging 91 PP100. Following in the rankings are Lexus, Lincoln, Honda and Mercedes-Benz, respectively. Honda, with the fewest problems per 100 among non-premium brands, improves in the ranking to fourth from sixth since the 2006 study and earns awards with the Civic and CR-V. Among non-premium brands, Kia posts the largest improvement in ranking, moving from 24th in 2006 to 12th in 2007 and earning an award for the Kia Rio/Rio5 for the second year in a row.

The most improved nameplates in the study are Land Rover (increasing in initial quality by 34 PP100), Saab (improving by 30 PP100) and Mercedes-Benz (increasing by 28 PP100).

Other nameplates receiving model awards in 2007 include Chevrolet (Express and Silverado Classic HD), Lexus (RX350/RX400h) Pontiac (Grand Prix) and Porsche (Boxster).

Assembly Plant Awards

For the first time since 1999, a North American assembly plant receives the Platinum Plant Quality Award for producing vehicles yielding the fewest defects. Ford Motor Company’s Wixom assembly plant in Michigan, which produced the Lincoln Town Car, averages just 35 PP100. Plant awards are based solely on defect counts.
