2022 MAZDA CX-30 Complaints

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.

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.

My infotainment system is brikecked ! I cant turn off my lane assist and its like a battle to keep it in roads that dont have lines and especially when you get stuck in a groove of a road. Its scary! I got put into a grove my car being awd the rest followed and I get out of the grove and lane assist put me back in amd it almost put me all the way into the same gaurdrail I just avoided. My car is im this state due to unaddressed parasitic draw killing multiple batteries all deallt with by mazda service department.

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.

The infotainment software is bricked. It happened when the battery died after purchasing it. The dealership told me to get a battery should be ok Now the infotainment system doesn't work and lane assist about put me into a guard rail the other day. I have no access to my cars functions and it is crazy scary

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.
