2022 Mazda CX-30 Complaints

LATCHES/LOCKS/LINKAGES,STRUCTURE — Filed 06/22/2026

1.5 years after purchasing new my passenger side front door would not open from the inside. Mazda states car is out of warranty at 36837 miles indicating a cable had come disconnected. Approximately 1.5 years later at 59934 miles the front passenger door again would not open from the inside. Mazda states that this door is used frequently (it is not) and after troubleshooting replaced the door handle and lock mechanism on June 22, 2026. Other than having out of pocket expenses of $738 I feel fortunate that I wasn't exposed to a life threatening situation whereby leaving the vehicle through the passenger side was my only option. Searching forums online show that this failure is currently occurring to others. My hope is that Mazda will formally recognize this issue with the passenger side front door before someone is seriously injured.

WHEELS — Filed 11/20/2025

The rear wheel bearing failed at approximately 50k miles, causing grinding noise, humming, vibration, steering pull. It was replaced by Mazda under warranty in 2025. The wheel bearing failed again at approximately 59k miles. I have seen reports from other CX-30 owners describing the same recurring wheel bearing failure. This is a known issue that Mazda has not been resolving for the owners and there need to be a recall for this issue.

1. The system that is failing is the rear tailgate. When it is opened or closed there is a clicking sound as if it is tryng to engage the lock multiple times. While driving this continues with the tailgate closed turning on and off the interior lights in the vehicle and showing on the front console that the tailgate is unlocked and open. the car is availabe for inspection on request. When I asked the dealer about it they stated that this is a known problem and it will cost approximately 800 dollars to fix which I believe is unresonable due to it being a known issue. 2. Since the rear tailgate may not lock properly it could potentially fly open while driving. 3. Yes see #1-Was reported to Kennedy Mazda located in Valparaiso Indiana. 4. Yes see #1 5. No warnings just the constant clicking of the lock mechanism can be heard.

WHEELS — Filed 09/02/2025

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.

ENGINE — Filed 07/06/2025

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.

ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 04/15/2025

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.

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 03/18/2025

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.

EXTERIOR LIGHTING — Filed 01/13/2025

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.

STEERING,VEHICLE SPEED CONTROL — Filed 10/14/2024

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.

UNKNOWN OR OTHER — Filed 08/16/2024

I travelled to Phoenix for a concert and after the concert I was driving back to my hotel room. I was traveling on the freeway and I heard a popping sound like a gunshot was hitting my window. I slowed down and ducked, thankfully no traffic surrounding me, only behind me. No vehicles were in front of me, as it was late at night, only two vehicles behind me and no overpasses. I pulled off the road, and found that my sunroof had exploded. It seems like the glass had blown from the inside shooting outward. It was very scary and thankfully no vehicles or heavy traffic as it would have caused an accident if there was. I’m not sure how anything could have hit the window because there was no traffic and no one in front of me to kick up debris. I did google and see that pressure changes have been causing this to happen to other vehicles and the only thing I can think of is the pressure changes of traveling to a new city which is very hot and driving with my ac on for long period of time possibly caused the sunroof to explode. It is currently awaiting repair at my local Mazda dealership now. The vehicle is just under 2 years old and has no damage. I don’t currently have any invoices because it’s still waiting at my local dealership.

STEERING,STRUCTURE — Filed 08/20/2024

The steering wheel seems to prematurely wear on newer Mazda vehicles including my Mazda CX-30 from 2022. Mazda claims hand sanitizer to be the main culprit but I suspect quality issues and materials to play a factor. Many can be found with wear on the steering wheel even starting with less than 50 thousand miles. Some have received warranty claims while others are denied.

It has an oil consumption issue. Every 3,000-3,500 miles is will give the oil low light. It will be 1 quart low. The car takes 6 quarts of 5w30 synthetic oil and requires oil changes every 7,500-8,000 miles. I have had to put a quart in every time. I have taken it into the dealership and a third party oil service as well. The dealership has no idea why it keeps running through the oil. They state that it's a known issue but no recall.

ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE — Filed 06/05/2023

There have been 3 different ongoing issues. The car was ordered and delivered brand new in April 2022. At 4,000 miles and again at 12,000 mile is would display low oil and require 1 quart of oil. The dealership acknowledged that it has an oil consumption issue, unresolved. I have to bring it in every time it is low prior to its required oil change time/miles. At 19,742 miles the cars battery died. They replaced it an have no reason why it died. Every time I'm driving in the mountain pass the transmission will not advance above 3rd gear. The engine will whine and I have to put it into manual and move it to 4th and or 5th gear. When I coming down the other side of the mountain, I have the same issue with it only advancing to 3rd and not proceeding to 4th or 5th. Then when I reach the bottom and on flat road the message- safety system and deactivated. This last for apx 10 minutes. The dealership has no idea why it does it.

TIRES — Filed 06/08/2023

On June 07, 2023, I was driving on the highway when I noticed a rumbling noise from the front driver-side tire (215/65R18). I got out and inspected the tires and observed nothing wrong with the tires. The next day (06/08) my wife was driving the vehicle on the highway (60 mph) and the vehicle started to shake. She pull the vehicle over and got out to check the vehicle. She observed the front driver-side tire sidewall was completely torn open. My wife never hit anything or ran over anything. The tire shop (Kost) could explain what happened to the tire. The shop person stated that it looked like a complete failure of the sidewall. The tire had approx. 9000 miles on it. In all my years of driving I never had a tire fail this bad.

FORWARD COLLISION AVOIDANCE — Filed 05/08/2023

I've used cruise control for decades and use it even on city streets, so I can concentrate on the road rather than my speed. The concept of adaptive cruise control is great, but the execution is very flawed on my Mazda CX30. The system fails to recognize lane separation and turn lanes where lines do not exist. The result is the Mazda CX30 adaptive cruise frequently brakes to slow the car for vehicles not in the lane it is in. At some point this is going to result in a rear end accident, because of other vehicles not allowing proper distance and my Mazda CX30 slowing for no valid reason. I shared this issue multiple times with dealership service, with Mazda via their website and with Mazda via emailed surveys. Dealership service says everything is working correctly. Mazda has not responded. If I could turn this functionality off, and have it stay off, I would do so and not report it here, but it turns back on every time the car is started. I was puzzled by this being an issue for me, on my Mazda CX30, but not for friends with other vehicles. What I learned talking to friends is that they rarely use cruise on city streets, which is the primary location for the issue. I discovered a Cheverolet Traverse, I rented, only beeped at me when it detected issues at locations where the Mazda CX30 slowed.
