Thanks to smaller engines, vehicle dependability falls for first time in 16 years

As automakers have made engines smaller and smaller to improve fuel economy, problems in those vehicles have gotten bigger and bigger. That's the synopsis of a J.D. Power vehicle-dependability study, which found that dependability dropped for the first time in 16 years, largely because the proliferation of four-cylinder engines is causing the vehicles to be less reliable. Specifically, the number of problems per 100 vehicles (or what J.D. Power calls PP100) during the past 12 months for 2011 model-year vehicles rose six percent from the year-earlier figures for 2010 model-year cars. Singling out four-cylinder vehicles revealed about a 10-percent increase in problems during the past year. This issues largely related to engine hesitation, rough transmission shifting and lack of power, signaling the inability of vehicle makers to iron out some of the problems in their smaller engines as they strove for better fuel economy. Six- and five-cylinder engines proved far more reliable. Among car brands, BMW's Mini sub-brand came out as least reliable, with 185 problems per 100 vehicles during the past year. Toyota's Lexus badge was easily the most reliable, with just 68 problems per 100 vehicles. Coming in second place was Mercedes-Benz. The overall average was 133. Check out J.D.

Power Reports: Increased Engine and Transmission Problems Contribute to Decline in Vehicle Dependability for The First Time in More Than 15 Years General Motors Company Receives Eight Segment Awards, While Toyota Motor Corporation Garners Seven and Honda Motor Company Earns Six WESTLAKE VILLAGE, Calif.: o Owners of 3-year-old vehicles (2011 model year) report more problems than did owners of 3-year-old vehicles last year, according to the J.D. Power 2014 U.S. Vehicle Dependability StudySM (VDS) released today. The study, now in its 25th year, examines problems experienced during the past 12 months by original owners of 2011 model-year vehicles. Overall dependability is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality. The study finds that overall vehicle dependability averages 133 PP100, a 6 percent increase in problems from 126 PP100 in 2013. This marks the first time since the 1998 study that the average number of problems has increased. "Until this year, we have seen a continual improvement in vehicle dependability," said David Sargent, vice president of global automotive at J.D.

Question of the Day: What's the greatest British car ever?

The British automotive industry has produced everything from high-production econo-commuters to staggeringly luxurious oligarch-wagons, along the way winning plenty of races and building plenty of beautiful machines. The original Mini led directly to the past half-century of transverse-engine, front-wheel-drive cars built everywhere, the MGB put the sporty little convertible into everyone's reach, and the Morris Oxford became the most beloved motor vehicle in India. So many to choose from, but we want you to pick one. What will it be? Related Video:

Mini boss contradicts reports on production Superleggera, says Minor unlikely

Mini has added to our green-beer-induced hangover with some disappointing news. The Mini Superleggera Vision Concept is not quite as confirmed as we had been led to believe. And making matters worse, the same high-ranking source that put the kibosh on confirmation of the stylish two-seater said he "doesn't see" a mini Mini. Mini boss Peter Schwarzenbauer contradicted yesterday's report in an interview with Automotive News, although he certainly doesn't oppose the idea of the Superleggera Vision. "I cannot confirm that it has been approved yet," Schwarzenbauer told AN, adding that it'd be a "great addition to the Mini range" and that he's "still pushing" for it to arrive in dealerships. That's good news for fans of yesterday's report. Schwarzenbauer is less of a fan of a small, entry-level mini Mini, based on the Rocketman Concept. "I don't see a smaller car than the current one," the exec said. It's long been rumored that Mini was readying a smaller, budget model that was more in line with the original Austin and Morris Minis, rather than the premium sub-compact model that BMW has been selling for the past 13 years. The company has even, allegedly, been in cahoots with Toyota to develop the new compact model. We reported as recently as January that the Anglo-Teutonic outfit and its Japanese partners would develop an entirely new platform for the Minor, although that certainly doesn't seem to be the case now. How do you feel about this? Does Mini need to get back to its roots with the affordable, Rocketman-based Minor, or should it keep on doing what it's doing? What about the Superleggera Vision Concept? Should Mini add it as a successor to the short-lived Roadster? Have your say in Comments. Related Video:
