Car Reliability Rankings 2011 - Even with Chrysler's improvement, Detroit models still have reliability problems. Of the 97 domestic models and versions for which we have sufficient data, 62 (64 percent) rated average or better in our new-car reliability ratings.
General Motors has stumbled after edging up last year. The Buick and Cadillac brands, in particular, appear to have taken a step backward; Chevrolet held steady and GMC dropped one spot.
The new Buick Regal and Chevrolet Cruze did well in our road tests but were below par in reliability. The Buick LaCrosse, an all-wheel-drive version of the Buick Enclave, and the Cadillac SRX were all deemed reliable last year but dropped to below average and are no longer recommended. General Motors' bright spots include the above-average Chevrolet Avalanche and the Cadillac CTS, which has improved to average.
The gas/electric Chevrolet Volt, with much better than average predicted reliability, ranks as GM's most reliable car but with a caveat: The sample size was just a little more than our minimum threshold of 100 cars, and most respondents had owned theirs for only a few months.
Ford's drop can also be attributed to problems with new technologies: the new MyFord Touch infotainment system and the new automated-manual transmission used in the Fiesta and Focus. Lincoln finished above Ford, although the freshened MKX, a cousin of the Edge, suffered from the MyLincoln Touch system. On the bright side, the Ford Fusion Hybrid sedan remained outstanding, and other Fusion versions were above average.
