Owner Narrative

A certified dealership service center improperly installed a mismatched tire configuration on a high-performance sports car (Nissan Z), creating an extreme handling hazard and vehicle instability. The service center replaced the rear tires with all-season Hankook tires while leaving the original summer performance tires on the front axle. This mix of entirely different tire categories has caused a severe traction imbalance between the front and rear axles. Upon acceleration, the vehicle experiences dangerous rear-end swaying, fishtailing, and an immediate loss of steering wheel control. The dealership’s shop foreman test-drove the vehicle and formally verified the handling instability and swaying defect. However, management has failed to correct the safety violation. The vehicle is currently deemed structurally unroadworthy and unsafe to operate on public roads due to this improper component
