The infotainment screen has spider like frost inside the screen. I've checked and other models have had this same issue and have been recalled and repaired. My model year 2018 is suffering the same issue and MAZDA has lagged on this problem. Please put out a recall on this as it is a hazard when you rely on your navigation system and other components the screen assists with.

GPS touchscreen developed cracks described as inside-frosting or spide-web. Mazda had a recall for 2015-17 years models for the same problem, but they are reluctant to recall 2018 models. In 2019, Mazda discontinued selling touch-screen GPS, but it refused to extend recall for 2018 models. I took my car to the dealership and the cost of repair is $2400. The dealer did not find any damage caused by external force. Hence, this is the same recall issue with poor hardware and craftsmanship. I would like to ask NHTSA to compel Mazda to do a recall for CX9 2018 GPS touchscreen.

Infotainment screen has spider cracking from faulty screen when manufactured. Open TSB stating this and Mazda refuses to replace under warranty after 5 months of owning vehicle, spider cracks got worse this year. When i got more spider cracks i contacted mazda support since the first time I contacted a local dealer. Mazda support denied replacement because “ i do not get my car serviced through mazda”, this screen issue has nothing to do with a car being serviced. This is a safety issue as you can not see parts of the screen and will only get worse and make the whole screen inoperable when using navigation.

Dec 2022 Crash

I was resting my foot on my brake in the middle of sealed traffic and when I eased up to move forward when traffic my brakes did stop causing me to bump the car ahead of me. After that what came next was that my car then accelerated forward with my foot still on the brake. By then 2 other vehicles were involved in this accident. My car is now totaled from this.

> I have a 2018 Mazda CX-9 with about 70,000 miles on it. Since 2020 this vehicle started developing cracks in the infotainment center screen. I only had about 23,000 miles on it at that time. the cracks are now starting to obscure my back up camera, communication system and nav system displays causing a safety issue. It is distracting to not be able to see clearly on this screen and I am afraid something will happen to me or my kids. About a year ago I did take this car to the local mazda dealer, for the longest time I thought I did something to it, but I did not. They called mazda customer service and no good will was offered. there is a technical service bulletin out but not a recall. There are several models older than my vehicle that have had this screen repaired free of charge by mazda. Same issue - nothing different then what is going on with my car. There are many many of the very same complaints online. can some please investigate this issue. it is ridiculous.

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.

The Mazda connect touch screen has started cracking in the corners 3 so far the past 4 months. I cannot feel the cracks. They are spreading and I am concerned eventually I will not be able to use my navigation. System at all as I will not be able to read it. I am concerned the touch ability will be lost. I understand many other Mazdas have this same defect but my model is not covered under the extended warranty like the other Mazda owners were given - the extended warranty covers vehicles older than mine. It is the same defect.
