Mazda
Cx-30

Rear wheel bearings failed at approximately 30,000 miles and were replaced by Mazda under warrantee. The same rear wheel bearings failed at approximately 72,000 miles and are available for inspection. Dealer has confirmed bad wheel bearings on both occasions. The potential for wheel bearing failure incudes loss of control of the vehicle while in motion. Dealer has bearing available for inspection. The only warning is increasing noise as the bearing wear.

At around 26,528 miles my 2022 CX-30 2.5s (not the turbo) developed a "Low Oil Pressure" warning while driving between 55-65mph on 07/06/2025. The car has had regular oil and filter changes about every 5K miles. The last oil and filter change was at 25,259 mileage on 05/25/2025. There aren't any visible oil leaks. I have read that this is a common problem for other Mazda CX-30 years 2021- 2022.

On April 15th, 2025, my 2022 Mazda CX-30 experienced a sudden malfunction while I was driving. Despite having the automatic emergency braking system and forward collision warning, the car failed to slow down or alert me before I hit another vehicle during a pile-up. Right after the collision, my dashboard lit up with multiple error messages about the forward collision system, brake system, and sensor malfunctions. I had the car towed to the dealership, where a full diagnostic scan was performed. It revealed multiple hard fault codes, including U0415 (Invalid Data Received from ABS Control Module), which I later found was listed in a recent Mazda recall (23V-487) affecting my exact safety system—but Mazda told me my VIN was not included. The vehicle was inspected by a certified Mazda dealership. Mazda has refused to take full responsibility despite the safety system failing and the car still being under warranty. My safety was put at direct risk because the brake system did not function when it should have, causing a wreck that could have been avoided.

There is a recall that doesn't include my car. In March before my service due date I got several critical notices on the dash) I-Activsense System malfunction, IActivsense advanced safey and driver support system not operating correctly, Have vehicle inspected. 2) Braking System Malfunction, Stop the vehicle in a safe place, 3)Safety and Driver Support Systems Partially Disabled 4) Vehicle Satus Monitor Serious Malfunction (1) Brake System Malfunction, Vehicle Warning Messages 1..IActivsense System Malfunction next service, which was in 4k miles. This with 19,700 miles on the car (bought with less then 5k on it). I pulled off the road and ate and got back in and all lights gone however 3/7, 3/18, 3/21, 3/22 it all came on again but was gone on arrival to dealership. I had brake fluid checked and it was almost empty, unusual and I know if it leaks and gets wet it corrodes discs, and that is the recall and that is what happened. So far no satisfaction from Mazda other than me paying to have it fixed including a complete brake system flush which should NOT be due till about 50k. I know CX 30 was recalled for this issue, they missed mine. Last service invoice In August says brakes are good, all fluids topped off, yet brake fluid was almost empty and corrision is not even front to rear, salt air is the same on both sides of my car. And why and where is the fluid? I had a third party check it before going in for service (he didn't touch because I'm under warranty but is experienced person in business) .. I will upload Aug and April service invoices. iNVOICE AT 15,374 miles states brakes are good and all fluids topped off, SO in 7 months brakes are destroyed fluid is empty at 19,687 miles. What happened if it wasn't recall problem? Warranty? I believe it should have been in recall.

The driver side front headlight bearing has failed. Noticed after 43K miles driven. This is a known failure due to a manufacturing defect (see technical bulletin issued by Mazda) however they won't cover the repair (~$1700) beyond 36,000 miles or 36 months. This is a manufacturer known safety issue which could impair visibility while driving at night and could result in a very dangerous situation. The only "warning" is a temporary fan noise after the vehicle shuts down. As a known manufacturing defect for the manufacturing years referenced in Mazda's technical bulletin, Mazda should cover replacement of the headlamp unit (the bearing is unable to be replaced in isolation) for at least through the life of the powertrain.

The temperature sensor is not working correctly. My engine is constantly reading cold and it’s affecting the performance of the car. There are already recalls on the 2020-2021 Mazda CX 30. I have the 2022

I am writing to report a serious safety issue with my vehicle, which resulted in a crash. While driving, I suddenly heard a loud sound, followed by an unexpected and uncontrollable shift of the steering wheel to the right. At the same time, the car unexpectedly accelerated, causing me to lose control and crash into a parked vehicle. The airbags deployed, and my car was totaled as a result of the collision. There were no obstructions on the road at the time of the incident, and the vehicle veered to the right without any prior warning. The car was purchased recently, with only approximately 3,000 miles on it and had been driven for just two months before this occurred. There were no warning signals or indications of any issues before the incident, and the car was in nearly new condition. This sudden loss of control, especially with such low mileage, strongly suggests that there is a serious mechanical issue, likely with the steering or related systems. I am requesting that Mazda thoroughly investigate this matter, as it clearly poses a significant safety risk. The vehicle has been towed to AAA Insurance for inspection, and I would appreciate your immediate attention to this claim. Please let me know the next steps in the investigation process. Thank you for your prompt attention to this critical safety concern.

Low oil level message on cluster 1000 mile away from my oil change mileage indicated by the dealer.
