MAZDA CX-9

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

Mazda North American Operations (Mazda) is recalling certain 2018 Mazda3, Mazda6, 2019 CX-3, 2018-2019 MX-5, CX-5, CX-9, and 2019-2020 Mazda2 vehicles. The impeller inside the low-pressure fuel pump may crack and deform, potentially causing the fuel pump to fail.

Risk: Fuel pump failure may cause an engine stall, increasing the risk of a crash.

SEAT BELTS:REAR/OTHER

Mazda North American Operations (Mazda) is recalling certain 2020-2021 CX-9 vehicles equipped with 60/40 split bench second-row seats. The left-side second-row seat may unexpectedly slide forward during a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 210, "Seat Belt Assembly Anchorages."

Risk: A seat that slides forward during a crash can transfer excessive force onto a belted occupant, increasing their risk of injury.

AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE

Mazda North American Operations (Mazda) is recalling certain 2007-2012 CX-7, CX-9, and 2009-2012 Maza6 vehicles. These vehicles had their passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

TIRES:TREAD/BELT

Mazda North American Operations (Mazda) is recalling certain 2019 CX-9 vehicles equipped with Sumitomo Falken ZIEX CT50 A/S tires, size P255/50R20 104V, having date code 1619. An incorrect rubber compound may have been used in the tire's manufacturing, allowing the tread to separate and detach.

Risk: A detached tire tread can decrease vehicle stability and increase the risk of a crash.

ELECTRICAL SYSTEM:WIRING

Mazda North American Operations (Mazda) is recalling certain 2018 CX-9 vehicles. The wiring harness may disrupt electrical communications and disable the passenger frontal air bag, turn signals, and/or engine starting system.

Risk: The passenger frontal air bag may not deploy, increasing the risk of injury. Inoperable turn signals prevent the driver from signaling to other drivers, increasing the risk of crash.

LANE DEPARTURE: WARNING

[XXX] 2018 MAZDA CX-9 GRAND TOURING 89014 MILES Date: 9/11/2025 To: Mazda North American Operations Attn: Customer Experience Center 7755 Irvine Center Drive Irvine, CA 92618 USA Subject: Formal Complaint Regarding Safety and Technical Issue – 2018 Mazda CX-9 Dear Mazda Customer Experience Team, I am writing to formally lodge a complaint regarding a serious safety and technical issue I have experienced with my 2018 Mazda CX-9. After a recent inspection conducted by Mazda Koch 33, it was brought to my attention that the engine wiring harness is defective and may potentially cause a fire or result in burns, posing a severe safety risk to me, my passengers, and others on the road. This issue is deeply concerning and unacceptable, especially considering Mazda’s reputation for reliability and safety. A fault in the engine wiring harness, particularly one that has the potential to ignite or burn, should be treated with the utmost urgency. It is troubling that such a critical component could present such danger. My vehicle has been serviced and maintained regularly, and I was not made aware of any recall or technical service bulletin that addressed this defect until the inspection. Given the nature of the defect, I believe this may be a manufacturer defect, and I request that Mazda: Immediately investigate and confirm whether this issue falls under an existing recall or known defect. Take full responsibility for replacing or repairing the affected wiring harness at no cost to me. Provide assurances in writing that my vehicle is safe to operate. Offer compensation or a loaner vehicle if the repair process renders my vehicle unusable for any period of time. Please consider this a formal request for immediate corrective action. I expect a prompt response within 10 business days of the date of this letter. If I do not receive a satisfactory resolution, I will be compelled to escalate this matter further through consumer protection agencies, such as the INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

STRUCTURE:BODY

To Whom It May Concern, I am writing to formally report a potential safety issue with my 2022 Mazda CX-9, which is a Certified Pre-Owned (CPO) vehicle under limited warranty until March 2026 and powertrain warranty until March 2029. It has 36,000 miles on it. Recently, I noticed a crack forming near the front combination light on the front bumper. The vehicle has not been involved in any accident, collision, or external impact. Upon researching, I found TSB Bulletin No.: 09-022/20, titled FRONT BUMPER CRACKED NEAR THE FRONT FENDER/FRONT COMBINATION LIGHT, which addresses similar cracks in 2016–2019 CX-9 models (VINs lower than JM3TC******306028). Although my vehicle falls outside the bulletin’s specified range, the crack appears identical in location and nature—suggesting a possible design or material stress issue that may extend beyond the listed VINs. When I brought this to the dealership’s attention, they declined coverage under warranty, citing the TSB’s limited applicability. Mazda corporate echoed the same response. I find this deeply concerning. Why is this issue being dismissed based solely on VIN range, without a proper inspection or consideration of safety implications? The crack is adjacent to lighting components and could compromise structural integrity. This is not a cosmetic flaw—it’s a potential safety hazard. I respectfully request that NHTSA investigate this matter and help facilitate a resolution, including repair or replacement of the bumper. It is disappointing that safety concerns are being overlooked in favor of technical exclusions and cost considerations. I urge NHTSA to consider expanding the scope of investigation to include newer CX-9 models not currently covered by the TSB. Importantly, I’ve seen many other CX-9 owners reporting similar bumper cracks in vehicles outside the TSB VIN range, particularly in Facebook owner groups. This suggests the issue may be more widespread than currently acknowledged and deserves broader attention.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I am submitting this recall request because my vehicle has experienced repeated incidents of a serious safety issue. While driving—most often on the highway—a warning appears that says “Smart System Brake Malfunction.” Immediately after, the car begins braking on its own without driver input. This has happened multiple times and, based on online reports, it appears to be affecting many Mazda vehicles across different models and years. Each time, I have been forced to pull over, turn off the car, and restart it to temporarily resolve the issue. This is extremely dangerous, especially at highway speeds, as it creates a high risk of rear-end collisions and sudden loss of vehicle control. When reported to Mazda, the concern was dismissed as a “sensor issue,” but the repeated nature and widespread reports suggest a potential systemic defect that requires urgent investigation and recall.
