AIR BAGS

On 06/18/2026, the vehicle displayed multiple safety warnings, including ABS malfunction, dynamic stability control/traction control malfunction, Smart Brake Support and Forward Obstruction Warning disabled, possible forward sensing camera malfunction, and airbag/seat belt pre-tensioner malfunction. These warnings involve braking, stability control, collision avoidance, airbag, and seat belt safety systems. This was not the first occurrence. On 04/24/2025, the vehicle displayed similar warnings, including critical brake system/Electronic Brake Force Distribution malfunction, ABS malfunction, Smart Brake Support and Forward Obstruction Warning disabled, possible forward sensing camera malfunction, and keyless entry malfunction. The vehicle was towed at that time. The vehicle was inspected by an authorized Mazda dealer in June 2026. The dealer replaced the battery under warranty, but I was not provided diagnostic trouble codes, a root-cause explanation, or written confirmation that the braking, ABS, airbag/seat belt, stability control, Smart Brake Support, Forward Obstruction Warning, and forward sensing/camera systems were fully diagnosed and verified safe. The dealer inspection report also listed the mileage as “No Mileage.” The vehicle is available for inspection upon request. I do not feel safe driving it because the repeated warnings involve braking, collision avoidance, stability control, airbags, and seat belt systems. I am concerned that an electrical, braking, or safety-control defect may disable safety systems while driving.

Sunroof glass failure that occurred on my 2024 Mazda CX-5. While driving to work on May 9th at 11:16 pm going 67 miles per hour on route XXX in [XXX] , I suddenly heard a very loud popping/explosive sound from above the vehicle. Upon safely pulling over, I discovered that the sunroof glass had shattered unexpectedly. There was no known object strike that I or my two passengers observed, no prior cracks or chips visible before the incident, and no warning signs of damage beforehand. The glass appeared to have exploded outward/ upward and appeared curved upward. Most of the glass we believe hit the vehicle behind us as it was gone by the time we were able to safely pull over. It was approximately 58 degrees outside with no inclement weather. The vehicle currently has approximately 53,000 miles and has been properly maintained. The incident was extremely startling and created a significant safety concern while driving. Luckily, the interior sun visor was closed when this incident occurred, preventing the glass from entering the vehicle and injuring myself or my two passengers. Because the vehicle is relatively new and the damage appeared sudden and unusual, I would sincerely appreciate Mazda reviewing this matter for possible warranty or goodwill assistance. I have always valued Mazda’s quality and reputation, and I am hopeful the company can help support resolution of this unexpected issue. I have attached photographs of the damage and would be happy to provide any additional information needed. I would also appreciate the dealership documenting whether any definitive impact point or external strike evidence was identified during inspection. Thank you very much for your time and consideration. I look forward to working together toward a resolution. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER

Passenger side headlight was making a loud noise. When it began, it happened sporadically, but in ~two weeks, it happened consistently whenever the car was on and could often be heard while driving. The sound was consistent with other reports of the headlight assembly failure and those covered by TSBs for 2019–2023 models. The vehicle was brought to the dealership, the noise was verified as being the headlight failure, and it was replaced under warranty.

ENGINE

While driving on the freeway, the car stopped having the ability to accelerate. The engine light came on, and I received a notification on the Mazda app stating there was an "engine malfunction." I took it to Mazda, and they told me nothing was wrong. Flash forward a month and the same exact situation occurred. I took it to Mazda, and they told me the same thing. This is incredibly dangerous, as losing the ability to accelerate on a very busy freeway is life-threatening.

VEHICLE SPEED CONTROL:CRUISE CONTROL

The contact leased a 2024 Mazda CX-5. The contact stated that the yellow electronic emergency brake light was displayed. The cruise control and rear brakes were inoperable. The brake pedal was pulsating while depressed. There was smoke coming from the front brakes. The vehicle was taken to a local dealer, who replaced the brakes, and the module was inoperable, but the failure recurred. The vehicle was taken to three independent mechanics, who determined that the rear brakes were firm. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 24,000.

STEERING

Incident Description: On multiple occasions in January and February 2026, while operating a 2024 Mazda CX-5 in reverse on low-friction surfaces (snow/ice) with a slight incline, the vehicle suffered a total systemic failure. System Failures: While reversing at low speeds, the engine spontaneously shut off without warning. This resulted in an immediate loss of power braking and power steering. Simultaneously, the electronic gear selector (shifter) became non-functional, preventing the vehicle from being placed into 'Park' to stop the uncontrolled rearward slide. Safety Risk: The vehicle became a "runaway" object on several occasions. In one instance, the vehicle narrowly avoided crushing a pedestrian against another parked car, stopping only when the tires reached a different surface texture. In a separate incident, the vehicle slid uncontrolled down a residential hill, striking snowbanks. There is a grave concern regarding whether the Supplemental Restraint System (airbags) remains functional during these engine-stall events, as the dealer could not confirm occupant protection status during a total power loss. Inspection & Reproduction: The vehicle was presented to an authorized Mazda dealer on March 3, 2026. The service department attempted to replicate the issue by reversing over soapy water on a gravel surface. However, due to the high friction of the gravel, they were unable to induce the specific tire-slip/low-traction conditions required to trigger the malfunction. No error codes were found during an informal scan, and no warning lamps or messages appeared prior to or during the failures. Component for Inspection: The vehicle is available for inspection. I believe the failure is rooted in the traction control or engine management software, which appears to improperly shut down the powertrain when it detects specific wheel-spin patterns in reverse, subsequently disabling critical safety systems including brakes and transmission locks.

Premature failure of headlight assembly unit, (buzzing sound, known issue) completely unacceptable for this to happen right out of warranty. I don't think I will touch another Mazda in the future.

EXTERIOR LIGHTING

My headlights have a motor (or motors) in them. This feature is to adjust headlights in accordance with the steering wheel. I think it's referred to as AFS (Adaptive Front-lighting System). The left headlight's motor makes a noise. I do not always hear it when driving but when stopped or parking and exiting the vehicle, I can hear it until the lights turn off. The car has about 37,000 - 38,000 miles on it.

Hello. I started hearing this noise on my car, it was distracting and found it that it only happens when my headlight is turned on. I believe that the headlight leveling motor went out, I have an appointment for next week to have it checked, but the more i reach out to others Mazda drivers, the more I hear this is a common issue. My car is brand new, well taken care of, this seems to happen a lot.
