If you’re having trouble working your car radio or can’t get your Bluetooth to function, you’re not alone. A recent Consumer Reports survey of its subscribers found that many drivers of newer model cars reported the high-tech controls were giving them a lot of trouble.

In the survey, covering more than a million vehicles, owners of Cadillacs, Fords, Hondas, and Lincolns had the most complaints with electronics. So Consumer Reports re-contacted thousands of them to explain what was wrong.

Sixty percent who had infotainment systems said they were difficult to learn, while one-third complained that a feature didn’t work properly.

Older drivers found the systems to be complicated to use at first. But younger drivers reported the most problems. That could be because they use the systems more.

Consumer Reports says its survey shows some electronic dashboard controls have been relatively trouble-free. They include the systems from Audi, BMW, Chrysler, and Lexus.
