For quite some time now, every button displayed on the screen in our 2015 Prius C two must be pressed immediately below their representation on the screen. The buttons on the bottom of the audio screen are almost impossible to press. You have to use your finger nail to pause or play. Is this a know issue with a known fix because either I don't know how to google it or it's a problem unique to our car. How can this be fixed? There was a time when it worked as expected and I don't know what might have caused this to start happening.
