Ford's’ PowerShift six-speed automatic proved to have a small fuel savings over traditional manual transmissions when introduced on the 2011 Fiestaand redesigned 2012 Focus. But they have brought reliability headaches since.
“We’ve seen a number of brands struggle with new transmission technology, ” said Jake Fisher, Consumer Reports’ director of automotive testing. “Whether it’s a complex system such as a dual-clutch gearbox, a continuously variable transmission, or one with eight or nine speeds. Many vehicles require repair and replacements because of rough shifting among the gears and slipping CVT belts.”
Not that all new-generation transmissions are troublesome. Audi and BMW have shown solid reliability from their respective eight-speed automatics for awhile, as well as Audi and VW with their shared dual-clutch technology. And the CVTs in Honda and Toyota hybrids have been strong performers.
Then there are manufacturers, such as Mazda, whose Skyactiv engines get great fuel economy while using a traditional, reliable six-speed automatic transmission.
“It really depends on the diligence of the manufacturer,” Fisher said.

Infotainment Troubles Continue

Meanwhile, the number of complaints associated with infotainment systems has increased. Common issues include unresponsive or crashing touch screens, or a reluctance to pair a phone. AcuraLink, Cadillac’s CUE, and Infiniti’s InTouch systems have been particularly problematic.
A close look suggests that cars with in-car electronics issues usually have other troubles, too, such as build-quality issues, squeaks, and other noises.
Some manufacturers are improving. Updates to Ford and Lincoln’s MyTouch systems have made them less troublesome year by year. Ford is replacing it with the Sync 3 system, so we’ll have to wait until next year to find out if that system turns out to be trouble-free.

I've worked at national magazines since the mid 1970s, and as an auto editor based at Consumer Reports' East Haddam CT auto-test facility since 1992. My first cars as a teenager were a 1950 DeSoto, followed by a 1949 Bentley Mark IV and a decrepit Jaguar XK120. I hope never to own a falling-apart classic car again. In my spare time, I collect 19th-century French clocks and do a little wood working
