Lexus Has Been Named the #1 Brand in Reliability

The new transmissions are helping automakers meet the rising fuel cost standards, but they're also require more trips to the repair shop. Transmission problems are hindering Honda, Nissan,  and all the other brands so says the  Consumer Reports' Annual Reliability Survey.  Drivers are reporting rougher shifting, clutch failure and even transmissions that had to be replaced twice in the first year of car ownership.

Lexus and Toyota, which rely on older transmissions in many of  their models, were the best performing brands in the survey.  Lexus/ Toyota has topped the survey since 2011.  Audi, Mazda and Subaru rounded out the top five.  The worst performers were Infiniti, Cadillac, Ram, Jeep and Fiat among the 28 brands.

The survey, released October 20, 2015 predicted the reliability of 2016 cars and trucks based on a survey its subscribers take each year.  This year's survey was based on responses from owners of  over  700,000 vehicles.  Consumer Reports'  Annual Survey is closely watched by the auto industry, since many potential buyers follow the Yonkers, New York-based company's recommendations.

Wall Street watches closely, also.  Tesla Motors' shares fell nearly 10 % after Consumer Reports said it would no longer recommend its Model S Sedan.  The Model S got high scores in the magazine's driving tests, but owners reported multiple mechanical problems.

Transmissions with more gears help engines run more efficiently.  A car with an eight-speed transmission gets about 8% better fuel economy than one with a four-speed according to the US Environmental Protection Agency.  Dual-clutch transmissions use separate clutches for odd and even gears, allowing faster shifting.  And continuously variable transmissions do away with fixed gears altogether, relying instead on a system of pulleys to produce an infinite variety of engine to wheel-speed combinations.

But new technology can cause problems.  Honda Motor Co. took a risk and put two new transmissions - an eight-speed dual clutch and a nine-speed - in its 2015 Acura TLX Sedan.  Consumer Reports said they had multiple problems, and the Acura brand slipped seven spots to 18th in this year's survey.  The Honda  Brand remains in the top ten, but it fell below Kia for the first time due to transmission problems, as well as glitches with the system.

Jeep, too, remained at the bottom of the survey because of problems with the nine-speed transmission in its new Cherokee SUV, which is made by the same company that supplies Acura.  And  continuously variable transmissions caused problems for Nissan and its luxury sibling, Infiniti.

Automakers often let buyers choose their engine and  transmission combinations, so buyers can avoid problems by opting for the older, more tested transmission, says Jake Fisher, Consumer Reports' Director of Auto Testing.  Brands that have consistently high reliability scores will also tend to have better transmissions.
Toyota has had few problems with the continuously variable transmission it introduced on the 2014 Corolla, for example.
"It often comes down to the manufacturer," Fisher said.  "If  Lexus starts unrolling eight-speed automatics, they're going to be fine."

Ford was the survey's biggest gainer this year.  Fisher said Ford ironed out problems with transmissions and infotainment problems that surface several years ago when the automaker introduced its new vehicles.  Volkswagen and Hyundai also improved as their models aged.

General Motors Co. had a mixed record.  Its Buick Brand is among the most reliable, but Cadillac fell seven spots to 25th because of problems with its dash-board infotainment system.

Tesla wasn't officially ranked because it only has one product, the Model S. But Fisher said responses from 1,400 Tesla owners indicted that Tesla has below-average reliability.  Owners reported sunroof  leaks and problems with the electric motor and the dashboard screen, among other issues.

How reliable is all this new technology, really? We'll just have to wait and see!
