Owner complaints3
UNKNOWN OR OTHER
Owners of the 2023 Mazda CX-9 report several distinct issues, with one severe incident involving a complete loss of vehicle control leading to a crash. In this case, the driver experienced total steering, braking, and acceleration failure, resulting in an uncontrollable vehicle and a subsequent crash, which caused injury. Another owner describes an unexpected sunroof implosion while driving, causing glass to scatter inside the vehicle, raising potential safety concerns. Additionally, there are complaints about the absence of a Traction Control Device switch, which leaves drivers unable to manually disable the system during adverse weather conditions, potentially leading to vehicle immobilization. These issues highlight significant safety implications, particularly the loss of control and structural failures, that prospective buyers should consider.
Owners of the 2023 Mazda CX-9 report issues with the 5-point harness crotch buckles on Graco TrioGrow and Graco TriRide car seats, specifically noting that the red button-release tension is insufficient. They describe situations where toddlers can depress the lower crotch buckle and free themselves while the vehicle is in motion, even when the harness is deemed tight and the chest clip is correctly positioned. This issue is consistently reported as a mechanical restraint failure, posing an ongoing safety hazard for young passengers. There are no specific mileage ranges or timelines associated with these complaints, but the safety implications are significant, as the restraint system fails to secure the child regardless of behavior.
Owner complaints2
SERVICE BRAKES
Owners of the 2023 Mazda CX-9 report two primary issues related to the service brakes. One complaint describes an automatic throttle control that reduces engine power to idle when both the brake and accelerator pedals are pressed simultaneously, which the owner experienced on a freeway. This feature is noted as potentially hazardous by the owner, especially in situations requiring simultaneous pedal use, such as on icy roads. Another owner reports a persistent brake pedal issue where the pedal must be pumped to engage the brakes properly, with the pedal otherwise going nearly to the floor. This problem has led to multiple repair attempts over four months without resolution, leaving the owner feeling unsafe. These reports highlight concerns about unexpected throttle behavior and brake pedal responsiveness, with significant safety implications noted by the owners.
Owner complaints2
STEERING
Owners of the 2023 Mazda CX-9 report issues with the steering system, particularly involving a thud sound from the steering wheel and a failed u-joint shaft, which later is identified as a bearing failure within the Electric Power Steering (EPS) unit. Complaints frequently mention delayed starts and critical malfunction alerts prior to steering issues, with one owner experiencing these problems just over 36,000 miles. In a separate incident, a steering wheel seizure at approximately 12,100 miles results in a crash into a ditch and a tree, with no airbag deployment or injuries reported. These issues suggest potential safety implications, particularly concerning steering control and braking, which may be of interest to potential used car buyers.
The 2023 Mazda CX-9 demonstrates solid reliability, scoring slightly above the segment average. With no recalls reported, the model shows a commendable track record in addressing potential safety concerns. The complaint distribution, while present, is limited, with no single issue overwhelmingly dominant.
