   The rearview mirror fell off when I lightly knocked with my sunshade. The Mazda dealership reattached the mirror when the car was in for an oil change. But then a year later, the same thing happened. I took my car to get an oil change at our regular mechanic and they re-attached the mirror, but then it fell off in my hand a week later when I tried to adjust the mirror. I took the vehicle back to the dealership to get the mirror reattached and they quoted me $105 to reattach the mirror. From my research on YouTube and Reddit, this is a common flaw of Mazdas and I do not believe I should have to pay to reattach a rearview mirror. I tried to reattach it myself, after watching YouTube instructional videos, and I successfully reattached it on 9/26/26, but then it fell off again when I lightly touched it to adjust the view. I have NEVER had this issue with any vehicle. It is a safety issue and should be fixed by Mazda for free.

   I am the original owner of a 2023 Mazda CX-30 AWD (VIN: [XXX]), purchased new on XXX from Mazda of Clearwater, [XXX]. This vehicle has experienced four separate warranty failure events involving critical safety systems within approximately 32 months and 44,530 miles of ownership. In June 2026, at approximately 44,500 miles, my 2023 Mazda CX-30 AWD exhibited sudden RPM lock and inability to shift, with delayed and jerky acceleration. Dashboard warning lights activated including transmission malfunction indicators. DTCs P0756 (Shift Solenoid B Stuck Off) and P0780 (Shift Malfunction) were set. The vehicle was taken to an authorized Mazda dealership. The dealer confirmed the concern and contacted Mazda's regional tech specialist. The valve body was replaced first per Mazda's direction; however, the vehicle continued to exhibit rough and delayed shifting on test drive. Mazda then directed the dealer to replace the full transmission assembly. The repair required 35 days at the dealership. This failure did not occur in isolation. The same vehicle had previously required warranty replacement of brake components (disc, caliper, pads) at approximately 26,400 miles due to a driveability concern, and battery and drive belt tensioner replacement at approximately 29,100 miles. An independent service record five months prior to the transmission failure confirmed transmission fluid was at correct level, ruling out neglect. The pattern of cascading safety-system failures — braking, electrical, and transmission — within 32 months on a low-mileage vehicle suggests a potential systemic manufacturing defect. The RPM lock and inability to shift at highway speeds represents a direct safety hazard to the driver and other motorists. All repairs were confirmed and performed by an authorized Mazda dealer under factory warranty. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

   Unexpected Automatic Emergency Braking Activation at Highway Speeds in Cold Temperatures. Description: I am reporting a safety issue with a 2023 Mazda CX-30 involving the collision avoidance / automatic emergency braking system. While driving at highway speeds, the system activates a forward collision warning (audible alert and dashboard indicator), followed almost immediately by automatic braking, even when there are no vehicles, obstacles, or pedestrians ahead. Conditions When Issue Occurs: * Ambient temperature: below ~40°F (4°C) * Road conditions: cold, often icy or snowy * Speed: highway speeds 45-75 * Environment: clear roadway, no visible hazards * visibility : clear System Behavior: * Audible warning and visual alert activate * Automatic braking occurs approximately 0.5–1 second after the warning * No obstacle is present to justify intervention Safety Risk: This presents a serious safety hazard because: * Sudden braking at highway speeds creates a high risk of rear-end collision * The warning-to-brake interval is extremely short, leaving little time for driver override. * Occurs in low-traction conditions, increasing risk of loss of control. * The event is unexpected and not predictable by the driver. Frequency: * Occurred multiple times under similar cold-weather conditions. * Appears repeatable based on temperature range. Attempts to Resolve: * Sensors/camera appear clean and unobstructed. * No prior collision damage to the vehicle. * Issue persists despite normal operation otherwise. * Similar reports observed from other owners in online discussions. This is not a one time occurrence, in the section below, i noted the last event but this is a daily occurrence in temperatures below 42F.

   While driving down the road a vehicle in front of me braked to stop for a bus loading kids, as I stepped on the brakes nothing happened and the vehicle surged forward. After the accident I viewed the vehicles onboard system status and it had logged several errors including errors to the activsense driver assist control. I used the vehicle’s emergency assist button and contacted 911, and reported the incident to ride share and contact my spouse. Police report lists the wrong time and vehicle but does have the correct vin number

   While attempting a left-hand turn, the steering wheel suddenly became stiff and unresponsive, as if the mechanical gear had bound. This sudden resistance made it impossible to complete the turn, causing the vehicle to strike a curb at low speed. A post-accident inspection at Lee Johnson Mazda (RO# 649854) confirmed extensive damage, including a bent inner tie rod, a damaged front wheel bearing/hub assembly, and wheel/tire damage totaling over $6,500. The dealership stated no electronic fault codes were present in the computer, but the physical behavior matches the 'sticky steering' symptoms currently under federal investigation for other Mazda models (Recall 24V022 / RQ26002). I believe a mechanical failure in the steering gear caused the collision.

   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.

    While coasting slowly through a parking lot at approximately 5-8mph I tapped the brake to slow further while making a tight turn and to safely pass a vehicle also turning towards me. This caused the car to lurch and accelerate as though my foot was on the gas pedal, but it wasn't. I had to step hard on the brake to bring it under control.

    While driving at approximately 20 mph on a residential road during slushy conditions, the side curtain airbags deployed without warning. There was no collision, no impact, and no indication of a rollover or crash. A police officer arrived and completed a report, which noted no crash had occurred. The airbag deployment caused damage throughout the vehicle, and the car has since been declared a total loss by the insurance company. The manufacturer initially delayed responding for over two weeks. When they did respond, they claimed the airbags deployed properly based on “connected data” indicating a possible rollover. However, they refused to provide any proof of this data, any Event Data Recorder (EDR) data, or any technical explanation of what triggered the deployment. No warning lights or messages were displayed before the deployment. The local dealership that had the vehicle inspected the physical damage but did not confirm a rollover or any significant structural event. Mazda has refused to release their investigation data and instead closed the case without transparency. This deployment caused significant damage and created safety and financial risk. I am concerned that this incident may reflect a larger issue in airbag deployment logic that other owners may also face.

    Others are at risk and below details how my safety was compromised. Powerlift gate/ trunk closed on my head and did not stop. It knocked me onto the ground and opened up a bloody gash on my head. Went to emergency room in the hospital to have them treat me with my head injury as I was bleeding with a head wound laceration. They sealed the wound with glue as it was in my hairline and gave aspirin for the head pain. There should be a safety feature on the power liftgate that alerts it if person or object is in the way. Other brands of vehicles have this safety feature. It is liability and there is concern for others of this happening that could potentially result in death. My injury has not fully healed as I know have recurring headaches and there will be a large scar left on my head. The vehicle is available for inspection.

    On February 18, 2024, at approximately 12:00 PM, while driving at 20 mph in slushy but clear conditions, my 2023 Mazda CX-30’s curtain airbags deployed unexpectedly despite no significant collision occurring. •What system failed? oThe curtain airbag system deployed improperly without a crash, severe impact, or rollover. oThe Event Data Recorder (EDR) should contain critical information on why the airbags deployed, but Mazda has refused to release this data. •How was safety put at risk? oThe airbags deployed while the vehicle was moving, which could have startled the driver and caused a crash. oThe deployment caused unnecessary damage to the vehicle, increasing repair costs. •Has the problem been confirmed or inspected? oPolice Report: No major collision documented. oInsurance Review: Travelers Insurance inspected the vehicle and found minimal external damage—most damage was due to the airbag deployment itself. oMazda Dealership Response: Tulley Mazda refused to retrieve EDR data, stating that Mazda considers it "proprietary." •Has the manufacturer responded? oI have been put on hold for hours, denied access to a case manager, and have received no meaningful response. oMazda appears to be refusing to investigate why the airbags deployed and will not provide any technical explanation. •Were there any warnings or error messages? oNo warning lights, messages, or symptoms appeared prior to the event. oThe curtain airbags deployed without any indication of an impending crash. Why this is a safety issue: If my Mazda CX-30’s airbags deployed unexpectedly at 20 mph, this could happen to other Mazda vehicles at higher speeds, creating a dangerous situation for drivers and passengers.

    I purchased a brand new 2023 Mazda CX – 30 from Cooley Mazda on September 27, 2023. I was excited to upgrade from my 2011 Mazda 3, however I have had issues early on. On June 7, 2024, I brought my 2023 Mazda CX – 30 in for diagnostic testing for front end noise and a shifting issue. I went out for a drive with the Technician and was told the noise I was hearing was from the weight of the car on the suspension, I disagreed. The Technician also experienced the shifting issue I spoke of, and I was told that the car needed to learn my driving technique, again I disagreed. At this point the vehicle only had 4014 miles on it. On July 25, 2024, I brought the vehicle in for its 1st oil change and tire rotation, as well as for the same noise and shifting issues. This time they found an issue with the front driver side front wheel bearing. They did not have the part in stock, so I had to wait for a call to schedule to come back once the part came in. Again, they claimed there was no shifting issue with the vehicle. At this point the vehicle only had 5079 miles on it. On August 7, 2024, I brought the vehicle in for replacement of the front driver side front wheel bearing. On my drive home I heard the same noise I brought it in for repair for. At this point the vehicle only had 5468 miles on it. On September 4, 2024, I brought the vehicle in for a NYS Inspection and for diagnostic testing on the noise and shifting issues, again they took the car out, did not experience the issue, but put it on the lift and did some testing which determined the car needs a new rear differential. At this point the vehicle only had 6219 miles on it. The rear differential was replaced and the vehicle still has shifting issues. It hesitates, sometimes doesn't advance when the gas pedal is pressed. The vehicle also hesitates at 38-40 and 58-60 mph while just holding your foot steady on the gas pedal.

    My brakes failed at a stop light. I was waiting at a red light waiting to get on the freeway . Brake was completely pressed, when my car started rolling forward. I kept trying to apply more force to brakes but was unable to stop the vehicle until it rolled into the car in front of me. I then had my car towed to Mazda and was told my accident was a result of human error. Inspection was done and no results were found. If my brakes had failed at any other moment my accident could have been deadly. There is a brake recall for my year make and model but my vin number is not yet apart of that recall. My car was barely a year since purchase I am the first owner .

    I have been the owner of a 2023 Mazda CX-30 since July 2023. On [XXX], 2023, I received automated warnings on the dashboard and through the Mazda App stating, "ActiveSense system malfunction. ActiveSense advanced safety and driver support system may not operate correctly." The service department at the dealership where I purchased the car explained that the sensors had overheated due to the hot weather. Unfortunately, a similar warning appeared on the dashboard on [XXX], and this time it resulted in damage to the car. On that day at 13:33, while maneuvering into a parking spot in the parking garage with my foot on the brake pedal, the car suddenly and rapidly accelerated and collided with a concrete post. Fortunately, I am unharmed but shaken, and the front of the car sustained damage. Immediately after the incident, I contacted the service department, explained the situation, and requested an emergency service to assess the car. The service department conducted checks on the brakes and suspension, performing a full-circle inspection. Their report stated, "Could not find any evidence to support the customer's claim." The service advisor expressed disbelief in the issue I described, stating he had not heard of such problems before. Contrary to the service advisor's disbelief, records on NHTSA.gov reveal numerous instances of sudden unintended acceleration while pushing on brakes for Mazda CX cars (CX5, CX30, CX50). These instances have occurred and have been reported nationally/across numerous states in the USA. I am urging Mazda to thoroughly investigate all reported complaints, issue recalls for affected cars, and enhance their safety features. As of now, there have been no reported fatalities, and it is crucial for Mazda to take proactive measures in investigating and addressing our claims to prevent any potential harm caused by errors in the ActiveSense system.
