Here are the biggest winners and losers from Consumer Report's annual auto survey

Consumer Reports released its annual auto reliability report and as expected some automakers fared better than others.

Lexus, Toyota, and Audi heads up the list as the most reliable brands while Fiat Chrysler's Fiat, Jeep and Ram brands came in as the least reliable based on survey results.

According to Consumer Reports, new transmission and infotainment technology account for many of the troubles faced by the brands that struggled in the survey.

"We've seen a number of brands struggle with new transmission technology," Consumer Reports' director of automotive testing Jake Fisher said in a statement.

"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."

Much of FCA's poor results in the survey can be attributed to the company's unreliable 9-speed automatic transmission, Consumer Reports' auto editor Mark Rechtin told Business Insider.

The reliability survey uses the responses from Consumer Reports' 8 million magazine and website subscribers. The publication then compiles responses on cars three years or newer to help predict the reliability of new cars. In total, the survey takes into account information from more than 740,00 cars.

Consumer Reports then ranks the predicted reliability from this years result to last year's outcome.

Of the 28 brands featured in the list, a handful made bigger moves up or down the rankings than others.
