Two problems related to wiper have been reported for the 2016 Mazda CX9. The most recently reported issues are listed below.
Multiple times while during inclement weather, pouring rain/sleet, the driver's side windshield wiper blade flew off of the car - causing a safety issue with visibility. We had to pull over to the side of the highway and switch to the passenger side's wiper blade, so that we could get to a safer place to be out of the way of traffic. It was night time during one incident and daytime during the other. The issue seems to be the way the wiper blade attaches to the arm.
Sunroof exploded while driving approx 40 mph. Were in a valley on vacation in colorado, no trees or anything overhead when this happened. We had just closed the windows and turned on the air conditioner as it was getting hot. About 2 minutes later we heard a loud explosion. Only when we pulled over did we discover it was the sunroof.
