Touchscreen control systems are among the items consumers are finding irritating about their cars these days, causing dips in quality ratings for many models. They say the devil is in the details and that's certainly the case when it comes to new cars and trucks. Most achieve admirable levels of performance, get stellar fuel economy, earn top safety ratings, and come packed with more features for the money than ever, but still no car is perfect. Motorists and automotive reviewers alike seem to be particularly frustrated with some of the motoring world's latest high-tech features these days – particularly complex infotainment systems that require a steep learning curve, and once mastered can still be difficult and distracting to operate. Dissatisfaction with common items like Bluetooth hands-free phone interfaces and voice recognition systems is causing some models to receive lower marks in owner surveys conducted by both Consumer Reports and J.D. Power.
