Mazda has refused to admit and repair a clearly defective screen, affecting visibility of the camera system, navigation, climate controls and infotainment. Pictures attached are several months old and the issue continues to get worse. The dealer says "corporate won't cover it", corporate customer service will not respond to repeated attempts at contact other than a generic "your VIN is not covered". Service alert direct from Mazda and pictures of my screen showing the EXACT issue are attached. For a $40k+ vehicle with less than 30k miles on it (less than 20k when the issue started), this is unacceptable. Please hold Mazda accountable.

While commuting home on 8/19/22 my CX-9 began overheating and coolant temp. warning light illuminated on dash. This was a dangerous situation as I had to stop in the middle of traffic for fear of ruining my car and risk getting rear-ended and also navigate to the shoulder of the road. Took the car to the dealership where they confirmed P111A engine overheated DTC and coolant leak. CX-9 has a cracked cylinder head, the exact problem outlined in Mazda TSB 01-013/21. This happened at 61,xxx miles...roughly 1,000 miles outside the powertrain warranty however it's highly likely this crack and leak developed well before the end of the powertrain warranty period.

"Spider Cracks" in both the left and right top corners that continue to spread, creating larger blind spots while in reverse. This is an issue that Mazda is aware of and impacts many models from 2014 until 2019. Even though this may not be considered a "safety feature" in it's traditional form, it has become common practice to rely on this feature while reversing the vehicle. Much like additional airbags may not be required, if they are, they should be fixed when they are proven to be faulty. Both the local dealer(Roger Beasley Austin North) and MazdaUSA refused to cover the cost of fixing the issue even though they are aware it is faulty. There is even a Service Notice that was put out by NHTSA that discusses this issue and my model is included, however I have been repeatedly told my VIN # does not qualify.

the Mazda Connect information screen has small spider cracks on the upper right part of screen that are inside the glass (if you run your finger over the crack it feels smooth). Information websites pertaining to Mazda vehicles say it's caused by temperature change.
