Consider it an example of the law of unintended consequences: When automakers started relying more heavily on high-tech four-cylinder engines and advanced transmissions a few years back, they certainly did achieve their goal of increasing fuel efficiency. On the other hand, that achievement seems to have come with some costs in the J.D. Power 2014 Vehicle Dependability Study (VDS). According to the recently released results, the industry's overall dependability rating worsened by about 6 percent when looking at Power's preferred VDS metric, "problems per 100 vehicles" (PP100).
The increase was from 126 PP100 to 133 PP100, with almost all of that difference attributable to powertrain concerns. Here, however, we run into one of the issues that make looking at customer-reported surveys like this a bit subjective. For example, David Sargent, vice president of Global Automotive for J.D. Power, called out three specific factors in the dependability decline: "engine hesitation, rough transmission shifts and lack of power."
Now, how well those customer complaints reflect a vehicle's dependability is open to argument, but regardless, new-vehicle shoppers can take solace in remembering that the 2014 VDS is based on the first three years of a vehicle's lifecycle; that is, all entries under discussion here are from the 2011 model year.
Getting down to specifics, that 133 PP100 industry average was exceeded by 16 of the 31 auto brands ranked in the 2014 VDS, with Lexus leading the way—by far—for the third consecutive year. The highest-rated non-lux brand was Honda, which finished sixth overall, while the automaker with most individual segment winners was General Motors, with eight. (And notably, that included the launch-edition of the Chevy Volt.)
The full list of top-three finishers from each car category follows; segments honoring fewer than three winners show just those with above-average dependability scores:
- Sub-Compact Car—Honda Fit, Kia Rio, Nissan Versa
- Compact Car—Chevy Volt, Toyota Corolla, Honda Civic
- Compact Premium Car—Lexus ES, Lexus IS, Lincoln MKZ
- Compact Sporty Car—MINI Cooper
- Midsize Car—Toyota Camry, Buck LaCrosse, Honda Accord
- Midsize Sporty Car—Chevy Camaro
- Midsize Premium Car—Lexus GS, Mercedes-Benz E-Class, Lincoln MKS
- Large Premium Car—Cadillac DTS and Lexus LS (tie)
- Large Car—Buick Lucerne, Toyota Avalon, Ford Taurus
