2018 Mazda CX-9

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.

The 2018 Mazda CX-9 has been experiencing significant engine coolant leaks, which are suspected to stem from a manufacturing defect. The coolant leaks appear to be primarily caused by a casting defect in the engine block or cylinder head, exacerbated by the pressure and heat from the attached turbocharger. These defects lead to coolant escaping from areas that are typically obscured behind the exhaust manifold and turbocharger, making early detection difficult without detailed inspection.

While I have not been involved in an accident yet, I have discovered an issue that is believed to be the same issue that other models are covered under a recall, yet for some reason my VIN is not included. The bulleting reference number is 02-001/20 that covers MAZDA 2016-2020 CX-9 models. I have a 2018 CX-9 touring that is exhibiting the exact action of the recall which is "creaking noise from front lower arm bushing/clunking noise from front shock absorber coil spring when driving over bumps". It is only getting worse as time goes on. I am confused as to why some vehicles would be included in this recall yet my year model is experiencing the same issues but is not covered under the recall. I don't know if people are not reporting it, which is why I am filling out this report today.

I recently bought a Mazda CX-9 and noticed that my vehicle was slightly overheating. The coolant level was very low. I took it back to the dealership I bought it from and they confirmed that there was a crack in the cylinder head and are working on the repair. After further research, I am seeing this is common with these models. Mazda is aware but not taking responsibility.

Cracked Cylinder Head Verified by Mazda Dealer . Noted it seems to be a very common problem with Mazda cx9 2018 models and has Multiple TSB on issue so I kept very close eye on car and took it in as soon as I smelled burning smell suggesting a leak , before the car had the chance to overheat and put myself and kids in danger. My car is under 40k miles for a 2018 with consistent maintenance - this is known problem since 2021 and needs to result in a recall.
