Technology problems involving infotainment, navigation, and communication systems continue to affect vehicle reliability, as increasingly reported problems again lowered overall scores in J.D. Power's 2016 U.S. Vehicle Dependability Study.

The report ranks vehicle brands in an index of problems per 100 vehicles. This year, the industry average came in at 152 problems per 100, an increase over the 147 problems a year ago. There were 133 problems per 100 in the 2014 study.

The study again ranked Lexus as the most reliable brand with only 95 problems per 100. Other top scores went to Porsche (97), Buick (106), Toyota (113), and GMC (120). At the other end of the spectrum, Dodge had the lowest score of 208 problems followed by Ford (204), smart (199), Land Rover (198), and Jeep (181).

Among the technological glitches, Bluetooth phone pairing was a point of contention with 53% of respondents reporting that the vehicle didn't recognize their device. Voice recognition systems also didn't fare well, as 67% said the system didn't recognize or misinterpreted verbal commands.

The number of engine and transmission problems decreased from a year ago to 24 from 26 in 2015.
