DETROIT--Issues with long-term automotive quality significantly affect consumer choice with most buyers choosing to switch brands on their next purchase if they experience even one major problem with their current car or pickup truck, according to an annual survey.

More than half of economy-vehicle buyers--who reported one issue with their vehicle when surveyed by J.D. Power and Associates in the past--bought a different brand on their next car-buying trip. Luxury drivers were more loyal, with 53% sticking with their brand with one issue. Two issues, however, and 53% switched. Issues included everything from mechanical and battery problems to wind noise, interior trim and electronics.

The willingness to abandon a brand underscores the challenges most of the world's auto makers face in the U.S. market as more consumers now expect their vehicles to remain reliable for a longer period of time. J.D Power, a unit of McGraw-Hill Cos. (MHP), compiled the data for the first time by surveying the buying habits of 8,000 people.

In this year's annual vehicle-dependability survey, Toyota Motor Corp.'s (TM, 7203.TO) Lexus brand retained the No. 1 spot while General Motors Co.'s (GM) Cadillac took a tumble from the top three finishers where it was replaced by Ford Motor Co.'s (F) Lincoln brand.

The survey, which measures problems experienced by original owners of 2010 model-year vehicles over a 12-month period, found Lexus leading the pack with the least amount of troubles, according to J.D. Power. Volkswagen AG's (VOW.XE) Porsche was second, followed by Lincoln and Toyota, which tied for third, and then Daimler AG's (DAI.XE) Mercedes-Benz. About 37,000 owners were surveyed. The results were released Wednesday.

Overall, vehicles are now more dependable than ever, with the lowest problem count since the surveyed was initiated in 1989. This is also the first time in four years there were fewer reported problems for all-new or redesigned models compared with older "carryover" vehicles that received no upgrades.

"There is a perception that all-new models, or models that undergo a major redesign, are more problematic than carryover models," said David Sargent, vice president of global automotive at J.D. Power and Associates. "Data suggests that this is not the case. The rapid improvement in fundamental vehicle dependability each year is more than offsetting any initial glitches that all-new or redesigned models may have."

Cadillac took a sizeable hit in the vehicle-dependability survey, falling from its third place finish a year ago to 14th place, also putting it below the industry average. The results are sure to be a disappointment for Cadillac, which is attempting to establish itself as a competitor to the current luxury-car players in the U.S. Cadillac is also pushing this year to make Cadillac more of a global brand.

Many of the problems with Cadillac were rooted in the 2010 SRX model.

"It wasn't the greatest launch," Mr. Sargent said. "We are not talking about the vehicle breaking down on the side of the road but there were some minor problems with a piece of trim falling off the vehicle which detracted from the enjoyment of the product. That has now been fixed."

Among the Detroit Three, however, Chrysler Group LLC, a unit of Fiat SpA (F.MI, FIATY), still found the majority of its brands languishing at the bottom again. Jeep, Dodge and Chrysler were both ranked among the seven worst. Mr. Sargent pointed out that the survey doesn't yet include the vehicle portfolio redesign initiated by Chrysler Chief Executive Sergio Marchionne after he took over the auto maker following its bankruptcy in 2009.

The redesigned versions will appear in next year's survey. Chrysler's one bright spot was the Ram pickup-truck brand, which jumped to the ninth spot overall. Last year, it was fourth from the bottom.

In a rundown of the rankings: Lexus had 71 problems per 100 vehicles, followed by Porsche, with 94; Lincoln and Toyota, tied with 112, and Mercedes-Benz, with 115. The industry average was 126 problems.

On the opposite end, Tata Motors Ltd.'s (TTM, 500570.BY) Land Rover finished last with 221 problems per 100 vehicles, followed by Dodge with 190, Mitsubishi Motors Corp.'s (7211.TO)Mitsubishi and Jeep tied with 178 and Volkswagen with 174.
