INFOTAINMENT SCREEN CRACKS: Common and known issue - when the vehicle is exposed to extreme heat or extreme cold, the expanding and contracting of the screen causes a spider-web cracking. The crack is internal between the screen and the plastic overlay and cannot be felt from the outside. The screen itself still works, but anything shown on the display under the crack is hard to see (ours unfortunately cracked where the time is displayed). For reference, we live in Ohio, and we let our vehicle sit outside under the sun (~85k miles/6 years old). It had a small crack the size of a fingertip when we bought it at 5 years old, but it expanded to the entire right-hand side after the summer started. I read that, even though it may not be under warranty, sometimes Mazda will still replace it since it's a known issue. Will find out soon, but I haven't contacted them yet.

My wife and I purchased a new 2016 Mazda CX-9 Grand Touring after falling in love with the sleek exterior and interior design and amenities, the significant technology features, and the great get up and go and smooth, yet sporty, ride. Zoom-Zoom! The week we purchased the car we took a fairly significant family trip from Southwest Michigan to Up State New York and back. The trip proved to be a great opportunity to break in the vehicle properly. I can't say enough about how enjoyable many of the features such as dynamic cruise control, auto-dimming headlights, lane keep assist, heads up display, adaptive front headlight, blind spot monitoring, and smart brake support front collision avoidance systems make this car to drive.

Unfortunately, however, my wife recently informed me she has began experiencing issues with the 8" full color touch screen display intermittently failing/turning off. Initially I expected there may be a button, switch, or configuration setting that allows you to turn the screen on and off she may have been unknowingly bumping or selecting. However, as the issue continues to occur completely intermittently while driving down the road, or at times sitting still, we have ruled this cause out. Additionally, I read the owner's manual and don't find mention of a method of turning the screen on and off with any switches or settings.

I plan to contact my authorized Mazda dealer this week to inquire about the issue and to schedule the vehicle for diagnostic testing and hopeful repair. My concern is this issue will not occur while I have the vehicle in for service and the failure is not something the computer diagnostic has registered or recorded. In the meantime, if anyone has any additional experiences to share and/or root cause, or preferably resolution to the problem, I am very interested in your input.

Thank you!
