One problem related to wiper has been reported for the 2016 Mazda MX5. The most recently reported issues are listed below.
Sun visors on first generation nd mx-5 subject to catastrophic failure, leading to dangerous driving conditions. I was at highway speed when the driver's side visor failed on my car. The visor would no longer stay in position. It just hung at the bottommost position. As a tall driver I first scrunched down in the seat in order to see properly out the windshield. Eventually I held the sagging visor up with my left hand and steered/shifted with my right hand. Not ideal and definitely not perfectly safe. Online forums indicate this is a widespread problem with first generation nds. Though the sun visors in my 2016 nd have been used sparingly, both driver and passenger side visors have failed in the same place: at the hinge near the dome light. The replacement part is nearly $300, not including installation. The part was quickly redesigned by Mazda but owners of early vins are out of luck.
