WESTLAKE VILLAGE, Calif. — A study by J.D. Power and Associates revealed that strong initial quality of 2009 model-year vehicles translated into historically high levels of vehicle dependability in 2012.

The 2012 U.S. Vehicle Dependability Study (VDS) measures problems experienced during the last 12 months by original owners of three-year-old (2009 model-year) vehicles. Overall dependability is determined by the level of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality.

"Despite facing immense challenges in 2009, automakers placed a keen focus on delivering outstanding levels of quality, which they understood would be essential to their long-term success," said David Sargent, vice president of global automotive at J.D. Power and Associates. "Three years later, owners of these models are enjoying unprecedented levels of vehicle dependability and manufacturers are experiencing market recovery. This is good news both for owners — who are holding onto their vehicles for longer than ever — and manufacturers, since perception of quality and dependability is a critical factor in vehicle purchase decisions."

Overall vehicle dependability averaged 132 PP100 in 2012, a 13 percent improvement and the lowest problem rate since the inception of the study in 1990, according to J.D. Power and Associates. The strong dependability of these models reflects their high levels of initial quality when measured three years ago. According to the company’s 2009 Initial Quality Study, overall initial quality of 2009 model-year vehicles was, at the time, the highest level of initial quality since the inaugural IQS in 1987.

Twenty-five of 32 brands have improved in dependability from 2011, while only six have declined and one has remained stable. Domestic nameplates have improved in 2012 at a slightly faster rate than imports, narrowing the dependability gap to 13 PP100 from 18 PP100 in 2011.

There are several brands that have performed very well in dependability during the past several years, but still face challenges with customer perceptions of their reliability, said Sargent. During the past four years, models from Buick, Cadillac, Ford, Hyundai and Lincoln have achieved consistently strong levels of dependability, but still have relatively high proportions of new-vehicle buyers expressing reliability concerns.

"Building vehicles with high levels of dependability is obviously a necessary element in reshaping consumer perceptions," Sargent said. "Negative quality perceptions are notoriously difficult to change, and it takes considerable time, but effectively communicating improvements in dependability may reduce concerns, and by extension, help new-vehicle sales."

Lexus ranked highest in vehicle dependability among all nameplates in 2012. The Lexus LS had the fewest problems in the industry, with just 72 PP100. Rounding out the five highest ranking nameplates were Porsche, Cadillac, Toyota and Scion, respectively. MINI and Scion posted the greatest year-over-year improvements from 2011 by 60 PP100 and 55 PP100, respectively.

Toyota Motor Corporation continued to perform well in long-term dependability and garnered eight segment awards, more than any other automaker in 2012, for the Lexus ES 350 (in a tie with the Lincoln MKZ); Lexus RX 350; Scion tC; Scion xB; Toyota Prius; Toyota Sienna; Toyota Tundra; and Toyota Yaris.

Ford Motor Company received three model awards for the Ford Explorer (in a tie with the Nissan Murano); Ford Fusion; and Lincoln MKZ (in a tie). General Motors (Buick Lucerne and Chevrolet Equinox) and Nissan Motor Co. (Nissan Frontier and Nissan Murano, in a tie with the Ford Explorer) each received two awards. The Hyundai Genesis received an award as well. Although there are no awards in their respective segments due to an insufficient number of award-eligible models, or insufficient market share of award-eligible models in the segment, the Ford Mustang, GMC Yukon and Porsche 911 also performed well.
