MAZDA Complaints

My 2023 Mazda CX-30, which is currently under full manufacturer warranty, was brought to the dealer on October 10, 2025, specifically to address a safety defect involving white chemical particulates blowing through the HVAC vents. The dealership confirmed the failure of the "evaporative coating", which resulted in unidentified chemical byproduct being discharged directly into the passenger cabin.The vehicle remained out of service for 103 days due to this manufacturing defect. Upon receiving the Repair order (RO# 77004584) today, January 20, 2026, I discovered a significant safety concern that violates standard warranty repair protocols: the technician admitted to receiving two separate heater unit boxes that were damaged during shipping and subsequently 'transferred all salvageable items "from one damaged unit to the other to make one complete unit". As a consumer with a vehicle under warranty, I am entitled to a repair using new, undamaged factory parts. I am extremely concerned about the structural and functional integrity of a "reconstructed" HVAC system assembled from damaged components. Furthermore, despite the confirmed chemical emission, no professional decontamination of the interior was performed. The manufactures is now using financial threats of storage and rental car fees to force me to accept this substandard, "cannibalized" repair.

I have a 2024 MAZD CX-90 Preferred Plus AWD. I was driving my [XXX] grandson to preschool and it sounded as though the passenger's door opened while I was driving. In the split second I looked back to check, unfortunately, I hit a guard rail. My grandson was buckled in his car seat. his first words were "Meme, the door opened but I didn't do it". He was buckled in his car seat and I believe the safety door locks were on. There was no warning sound or light indicating the door was open while I drove. I pulled over, got out of the car and looked. the passenger's back door handle was positioned up but the door was closed. being so shook up, I didn't think to take any pictures. I then had messages on my car saying Dynamic Stability control malfunction - have the vehicle inspected and Engine Malfunction - have the vehicle inspected. I called my dealership to find out if there were any recalls on this type of problem (they said that there weren't any). I have come across a forum where a person states: "So can confirm 1st row passenger door does not provide any warning as well. Looking at the manual, I see that there is supposed to be a warning sound when any door/hood/liftgate is open while driving, as quoted below. If someone else confirms this is normal behaviour, then I think we should file a safety defect complaint with the NHTSA and Transport Canada. “Door-ajar Warning Light/Liftgate-open Warning Light/Hood-open Warning Light The light turns on if any door/liftgate/hood is not closed securely. In addition, the warning sound is activated if any door/trunk lid/liftgate is not closed and the vehicle is driven. Close the door/liftgate/hood securely.” This was a very scary situation. I absolutely will concede that something did happen with this rear passenger door. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at highway speeds (approximately 50–55 mph) on a highly curving road, the steering intermittently became difficult to control. The steering wheel felt locked or stuck in a turned position and required excessive force to return to center. This condition occurred repeatedly over a 14-mile stretch of curvy highway and resulted in a partial loss of steering control, nearly causing collisions with another vehicle on multiple occasions. This incident occurred at approximately 16,900 miles. Although this defect has occurred multiple times since the vehicle was purchased, this was the most severe occurrence and posed a significant and imminent safety risk. The condition was reproduced and confirmed by an authorized dealer, who advised that replacement of the steering rack is required. At no time did any warning lights or messages appear to alert the driver to this dangerous condition. This issue represents a serious safety defect and warrants investigation.

Passenger dash has cracked some and dash is very very sticky..why has this happened..I feel if airbag had to deploy it would not because of this situation

Blend door actuator linkage will not allow for heat to be turned on, will blow cool/cold air, have had it looked at and the gear teeth will not stay in line with on another to be able to turn when the knob inside the car is turned. I was told that this may be a recall but do not see anything listed, but that it is a known problem for this model of mazda 3 and ford expiditions

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The airbag system, specifically the curtain airbags and related airbag control components, malfunctioned by deploying spontaneously without any collision or impact. The vehicle and deployed airbags are still available and can be inspected upon request. 2. How was your safety or the safety of others put at risk? The spontaneous deployment of all four curtain airbags created an immediate safety hazard. Airbag deployment can cause injury, disorientation, or loss of control, especially if it occurs unexpectedly. Although the vehicle was stationary at the time, deployment without warning posed a serious risk of injury to occupants and could have resulted in a crash if it had occurred while driving. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has not been reproduced, as the airbags have already deployed. However, the spontaneous deployment itself is clear evidence of a malfunction. The issue has not been resolved or repaired, and responsibility for repair has not been accepted. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The incident was reported to Progressive Insurance, which denied coverage because there was no accident or collision. The vehicle has not yet been inspected by the manufacturer for defect analysis. No police inspection occurred because there was no crash or injury. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The airbag warning light was illuminated prior to the incident, indicating a potential system fault. Additionally, a strong chemical odor was noticed inside the vehicle immediately before deployment, originating from the front passenger side, moments before all four curtain airbags deployed.

Steering wheel gets stuck when turning steering wheel, will not come back to center. Almost lost control on the freeway when steering wheel got stuck. Took it to the dealership and was told this is normal. Even though I found Recall 6524A.

Drivers side LED headlight cooling fan is making a loud buzzing noise 100% of the time when the headlight is turned on which indicates that the fan is failing. If fan fails, it will lead to overheating and failure of the headlight. Vehicle was inspected by Mazda to confirm the issue. Mazda issues Service Alert SA-013/23 and Technical Service Bulletin 09-015/23 have been issued for this problem. TSB states: Some customers may notice an abnormal noise (i.e. whine, groan, rattle or squeak) coming from the front combination lights when turning them on, or a few minutes after turning them off. The noise may be due to contamination by foreign matter during the manufacturing process. The fan motor bearing may become worn out during use. To eliminate the noise, the production process at the supplier and the material has been modified.

On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair. The police did not respond to reported incident. Incident was reported to my insurance company immediately.

Description On 12-15-2025, in 18°F weather, the vehicle was parked on a residential sloped driveway with the manual parking brake fully engaged. While the driver was outside the vehicle, the parking brake system failed to hold the car’s weight. The vehicle rolled backward, crashed through a wooden railing, teetering on a 4-foot retaining wall, and came to rest over a culvert. Two young children were inside the vehicle at the time of the failure. Component Failure & Availability: The manual parking brake system failed to provide sufficient holding force to secure the vehicle. The rear brake calipers are currently available for inspection. Safety Risk: The safety of the two children inside the vehicle was put at extreme risk due to the unexpected movement of the car. This failure matches the exact conditions and consequences described in Safety Recall 1217F (NHTSA Campaign 17V-393), which states that "unexpected movement of the vehicle if parked on a slope" increases the risk of a collision. Reproducibility & Confirmation: The failure occurred under the specific environmental triggers (cold temperature and slope) identified in the manufacturer's own safety recall documentation. However, the manufacturer has officially refused to authorize the internal teardown of the actuator shafts—the only diagnostic method capable of verifying the rust and sliding resistance that causes this loss of holding force. Inspections: The vehicle has been visually inspected by an authorized dealership and insurance representatives. The manufacturer has declined the necessary internal mechanical diagnostics to verify the internal defect. Warning Symptoms: There were no warning lamps, messages, or symptoms prior to the failure. The parking brake felt fully engaged at the time the vehicle was parked.
