Porsche Boxster On Top – Consumer Reports’ 2010 Reliability Survey

The misconception prevails in the society about the sports cars that they are not reliable and can only be used sparingly for the fear of an expensive repair. This concept seems baseless, as the Porsche Boxter, a sports car has been rated the most reliable car in the whole world, says the Customer Report’s New 2010 survey.

Porsche Boxter has already been proven one of the best models from Porsche in terms of reliability, acceleration, predicted depreciation, and not to forget the accident avoidance in Boxter is almost flawless.

The Porsche’s 911, is considered as one of the worst model from Porsche, but yet it scores well. In most categories, both the 911 and Boxter scored almost the same. The major difference between the two laid in owner and fuels costs and of course the reliability is a bit lower.

In the survey, the only company that seemed prominent than others was the only German automakers, Porsche. The rest of the companies like Audi, Mercedes Benz and BMW came in the bottom ten. The high performance M3 ranked the worst BMW, with the 135i ranking the highest.

There were sports cars which failed to make any impact on the people include the M3, Mazda MX-5, Chevrolet Corvette Z06 and Miata Cadillac CTS-V. Besides Porsche, only one company that ranked on the top with its sports car, the Genesis Coupe was Hyundai.

Press Release

General Motors has improved considerably, though Honda and Toyota still dominate in the latest predicted-reliability Ratings of new cars, according to Consumer Reports 2010 Annual Auto Survey. Eighty-three percent of Chevrolets, General Motor’s major brand, now have average or better scores in predicted reliability, up from 50 percent last year. (See our car Reliability special section, for more details, lists, and ratings.)

While some GM nameplates had been among the least reliable brands in past years, they now rank above some major European competitors such as Audi, BMW, and Mercedes-Benz. Two factors are aiding GM’s reliability improvements. First, GM’s recent introductions, such as the Chevrolet Camaro and Equinox, Buick LaCrosse V6 (FWD), and Cadillac SRX, are proving reliable from the time they were launched. In addition, GM shed many models with subpar reliability when it shut down the Hummer, Pontiac, and Saturn brands. Even some older models, such as the Chevrolet Avalanche, Corvette, and Suburban have improved to average.

As a company, GM is still a ways from the top when it comes to reliability-the major Asian automakers, including Honda and Toyota, are still out in front. Among the three domestics, Ford continues to build the most reliable vehicles. Chrysler lags behind both GM and Ford. Still, GM made the most progress of the three domestic manufacturers in this survey. Across GM brands (Buick, Cadillac, Chevrolet, and GMC), 69 percent of models had average or better reliability. Cadillac improved the most, rising seven places from last year’s ranking. Chevrolet had its best showing in years; 83 percent of models had average or better scores in predicted reliability, up from 50 percent.

In the new survey, based on 1.3 million vehicles, 90 percent of Fords, including Lincoln models, have at least average reliability. As a brand, Ford now outranks Mazda and Nissan and ranks just below Lexus. Its quality renaissance has been led by the Fusion, a design that has been very reliable since its debut five years ago. Ford vehicles are tops for reliability in two categories: family cars (Fusion Hybrid) and large SUVs (Ford Flex EcoBoost).

Chrysler Corporation hasn’t shared in the success of the other Detroit manufacturers. The Chrysler, Dodge, and Jeep brands are saddled with dated models. Twelve of the 20 models that CR had sufficient data for rate below average in reliability. None of Chrysler Corporation’s models score above average. With Fiat’s acquisition of Chrysler, many of its products will either be replaced or redesigned in the near future.

Asia Still Dominates

Despite recent safety recalls, Toyota models, including those from Scion and Lexus, remained among the most reliable and earned top scores in five vehicle categories: small cars (Yaris), midsized SUVs (FJ Cruiser), luxury SUVs (Lexus LX), minivans (Sienna V6, FWD), and full-size pickups (Tundra V6). Only the all-wheel-drive Lexus GS and the new Lexus IS 250 convertible are below average. The redesigned 2010 Toyota Prius, hurt by antilock brake problems on early vehicles, scored only average. That is quite a drop from previous years.

Honda and Acura are among the top four brands along with Porsche and Scion, with their models topping five vehicle categories-upscale cars (Acura TL, FWD), luxury cars (Acura RL), small SUVs (CR-V), upscale compact SUVs (Acura RDX) and compact pickups (Ridgeline). Problems with rear brake pads help drop the four-cylinder Accord and Acura TSX to average.

Hyundai and Kia continued to do well, with only one model, the Kia Sedona minivan, rated below average. All six new models for 2010 (Hyundai Genesis Coupe, Sonata, and Tucson; Kia Forte, Sorento, and Soul) had average or better reliability-an impressive first-year showing.

Nissan’s mainstream models scored well. The Altima and Maxima sedans; the Murano and Pathfinder SUVs all rated average or better in predicted reliability. The Titan had shown improvement in the last year or two, but both 2WD and 4WD versions have once again dropped to below average reliability. The small Nissan Cube had a below average score in its first appearance in Consumer Reports survey. The Infiniti models were all average or better.

Subaru had a good record overall, with a top rating going to the four-cylinder Legacy sedan and the non-turbo version of the Forester SUV. The WRX was the only model that rated below average.

Europe’s Bumpy Road

While European reliability had been improving, momentum seems to have stalled. All Porsche and Volvo models are rated average or better. But Audi, BMW, and Mercedes-Benz are among the worst automakers overall in terms of reliability.

BMW had a bad year, with five of its 11 models scoring below average. While the BMW M3 topped the sporty cars category, the 1-, 3-, and 5-Series models with the 3.0-liter turbocharged (N54) engine had high problem rates related to the fuel system, among other gripes.

Six of Mercedes-Benz’s 13 models were below average, and the GLK SUV was far below average. However, the redesigned E350 sedan was above average-a promising start. The new E-Class coupe, a wholly different car from the E-Class sedan, languished in the bottom ranks.

Nearly three-quarters of the Audi models Consumer Reports analyzed were below average. The A6 3.0T with the new supercharged 3.0-liter V6 was tied with the Jaguar XF for the worst new car prediction score. Volkswagen did better, with its Golf, formerly the Rabbit, doing very well and the various Jetta models scoring average or better.

The Porsche Boxster has the best predicted reliability score in Consumer Reports survey.

Consumer Reports Auto Reliability Survey Details

The findings are based on responses on 1.3 million vehicles owned or leased by subscribers to Consumer Reports or ConsumerReports.org. The survey was conducted in the spring of 2010 by Consumer Reports’ National Survey Research Center and covered model years 2001 to 2010. Consumer Reports’ expert team of statisticians and automotive engineers used the survey data to predict reliability of new 2011 models.

Predicted reliability is Consumer Reports’ forecast of how well models currently on sale are likely to hold up. To calculate predicted-reliability ratings, CR averages the overall reliability scores (used car verdicts) for the most recent three model years, provided that the model remained unchanged in that period and also didn’t substantially change for 2011. If a model was new or redesigned in the past couple of years, one or two years’ data may be used, or if that’s all that’s available.

On rare occasions Consumer Reports make predictions for a newly redesigned model, but only if previous versions had outstanding reliability.

Consumer Reports Annual Auto Survey Reliability Ratings are unrelated to Consumer Reports vehicle road-test results, but are a key factor in determining whether or not Consumer Reports recommends a car. CR only recommends models that have performed well in tests conducted at its 327-acre Auto Test Center in Connecticut, and that have average or better predicted reliability based on its annual survey. In addition, vehicles must perform at least adequately in government or insurance industry crash and rollover tests, if tested, and have electronic stability control (ESC) readily available in a mainstream high-volume trim line in order to be Recom
