“Hi, I have a 2019 Mazda CX-9. It is a certified pre-owned vehicle we purchased in October 2020. Upon going out to our car yesterday, June 12th, 20212, I noticed that the top left of the center console screen appeared to be damaged. I was perplexed because the car was locked and it wasn't there previously. As I touched the screen, I realized that cracks/peeling were all internal within the screen. I immediately decided to Google the issue to see if others have had similar experiences, and I found dozens and dozens of examples. …”
NHTSA complaint #11469053, filed 2022-06“Vehicle infotainment screen is developing a spider crack which its expanding over time; screen won't be usable in the future and/or may crack completely at any moment. Mazda is aware (Service Alert No.: SA-008/18 and Campaign SSPB9) and unwilling to replace/repair the faulty display, car is from 2019 with 45k miles and out of basic warranty . I was told that if regular services (oil change etc.) were done at the local dealer (Mazda of North Miami)they would have probably helped me with this issue.; last service with local dealer was on 06/2022 for another warranty claim. Very disappointed. …”

The contact stated that while the vehicle was idling at a red light the dash board warning lights suddenly activated and illuminated and while driving the vehicle would not properly accelerate. Shortly after parking in the driveway and exiting the vehicle moments later flames and smoke was present coming from the rear passenger side of the vehicle. The husband used water to extinguish the flames and the vehicle was towed to the local dealer. During the incident no injuries were reported and no fire or police report was filed. …”
NHTSA complaint #11477407, filed 2022-08, 61,000 miles“2019 Mazda CX-9 GT Infotainment Screen is spidering / cracking in the upper right-hand corner making it difficult to see information on the screen. This appears to be an ongoing problem with the design / components of the infotainment screen. I note a May 2020 TSB / Dealer Notification campaign which extended the warranty coverage period to 7 years for this exact same issue in 2016-2017 model year CX-9s. The 2019 model year cars have the exact same problem and Mazda is not covering the issue.”
