Problems with infotainment systems, from frozen touch screens to poorly performing voice-operated navigation systems, were frequent complaints. Jake Fisher, Consumer Reports' automotive testing director, said electronic problems may even be underreported, since some drivers find the systems so confusing they don't use them. German cars tended to have the best infotainment systems.
The 2014 Subaru Forester got the top score for predicted reliability, but the magazine noted that the 2014 Forester had only been on sale for a few weeks in the spring when owners were surveyed, so there wasn't much time for errors to crop up. The Subaru Legacy was the top-performing midsize car.
Electric cars and hybrids generally performed well, but the Ford C-Max Energi plug-in hybrid got the worst reliability scores. Ford and its luxury Lincoln brand were near the bottom of the rankings because of customer complaints about their glitch-prone touchscreen dashboard systems and lower-than-expected fuel economy numbers.
The key to reliability is a conservative approach to vehicle redesigns. The brands that do best, like Toyota and Honda, often use time-tested engines, transmissions and other parts from prior models in their newer cars, Fisher said. Automakers with new engines or other untested features in their new cars like Ford or Cadillac tend to do worse.
"When you redesign cars from the ground up, you're going to expect those issues," Fisher told The Associated Press.
Brands with many older models, like GMC and Volvo, also tend to do better.
