2023 Mazda CX-9

I am reporting a critical mechanical restraint failure regarding the 5-point harness crotch buckles on the Graco TrioGrow and the Graco TriRide car seats. The red button-release tension on both of these models is engineered with insufficient physical resistance. My toddler is capable of physically depressing the lower crotch buckle and completely freeing themselves while the vehicle is traveling at highway speeds. The harness was explicitly verified as tight via the pinch test and the chest clip was at armpit level, proving the failure is strictly the low force required to disengage the buckle.I contacted the manufacturer (Graco), and their customer support agents dismissed this hardware failure by suggesting 'behavior modification' instead of addressing the mechanical vulnerability. A child restraint system must physically restrain the occupant regardless of behavioral variance. This is an active, ongoing safety hazard for young children traveling in these specific models.
