2018 Mazda CX-9

Infotainment screen (LCD) of Mazda CX-9 2018 has developed what looks like discoloration/scratching/frost in corner of screen about 2 years ago and it is continuing to spread over last 6 months. This screen is used for hands-free bluetooth/calling (which is now the law in Iowa) and the back-up camera which allows for safe backing. If screen is unreadable, these safety functions cannot be performed properly. I take my car into Mazda dealership for maintenance/oil changes and it has never been addressed as an issue, but I'm concerned.

1. The navigation has a frosted crackle appearance framing the screen. It is difficult to read the navigation when needed. I know this has happened to other models of this vehicle and those were recalled and covered. 2. The brake senor keeps going off stating "SMART BRAKE SYSTEM MALFUNCTION". This goes off repeatedly while driving. 3. Then a second message pops up and reads "FRONT RADAR SENSOR SYSTEM MALFUNTION".

Approximately three weeks ago, a message on my dashboard said to pull over immediately. Your car is overheating. I pulled over to a nearby auto shop, which indicated that I was just low on coolant. They topped off the coolant, and everything appeared fine. Two weeks later, I got the same message on the dashboard, saying my car was overheating to pull over immediately. I pulled into a nearby auto parts store and purchased coolant for the vehicle. When I checked the reservoir, it was bone dry. I added coolant and drove the car home. The following day, I checked the reservoir to see if there was still coolant, but it was all gone. I scheduled an appointment with the Mazda dealer to have the car inspected. I also checked the Mazda Forum website to see if other vehicles of my make and model had similar issues since I had never experienced this before. I found that the overheating in vehicles of my make and model was a "known issue" with Mazda. When I took it to the dealer the next day, the service agent informed me that the "known issue" was only with the Turbo model. I explained that my vehicle is a turbo model. He said that Mazda did not have to cover any costs because no recall was issued, even though it is a known issue. Mazda is now refusing to cover the repair and has indicated that the repair and replacement of the engine will cost approximately $9800. If I had been alerted earlier, I would have been able to have the car repaired.

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.

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.
