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 recontacted thousands of them to explain what was wrong.
Sixty percent who had infotainment systems said they were difficult to learn. And one-third complained that a feature didn't work properly.
More older drivers found the systems to be complicated to use at first. On the other hand, younger drivers reported the most problems. That may 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.
