FORWARD COLLISION AVOIDANCE — Filed 03/04/2026

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.

UNKNOWN OR OTHER,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 12/17/2024

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

STEERING,SUSPENSION,WHEELS — Filed 02/01/2026

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.

UNKNOWN OR OTHER — Filed 10/10/2025

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.

ENGINE — Filed 12/18/2025

One day after oil and filter change, engine LOW OIL LEVEL light illuminated on dash. Engine oil dipstick displays full oil level; no signs on oil leaks under the vehicle. Appears to be failed oil level sensor. Upon restarting the vehicle, LOW OIL LEVEL light is turned off. Intermittently returns after some time of driving. Have not observed light turning itself off without shutting down the vehicle.

VEHICLE SPEED CONTROL — Filed 07/29/2025

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.

AIR BAGS — Filed 02/18/2025

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.
