NHTSA Complaint #11681156 — 2025 MAZDA MAZDA3

January 10, 2025, at low city speed, I struck a small pothole. The entire car felt like it had been in an accident—a violent jolt—followed by immediate vibration and a pull. Inspection showed one OEM 18" rim was bent. I contacted Mazda after diagnosing and was offered a slight discount on the replacement rim, not a warranty repair or full diagnosis. I have the bent rim in my possession. July 2025, at low speed, I barely contacted another small pothole and immediately felt the same drivability issues. A second rim was found damaged. This was only 4,500 miles after the first incident. I called the dealership manager; he said he would get back to me but never did. I later sent a letter that went unanswered. My subsequent research shows innumerable similar owner complaints for 2020–2025 Mazda 3s experiencing rim deformation from ordinary road irregularities. Why this is a safety issue (technical points): Bead-seat deformation & air loss: A bent alloy rim can distort the bead seat, causing slow leaks or sudden deflation, especially after heat cycles—creating a loss-of-control risk. Dynamic instability: A rim that’s even slightly out-of-round produces high-frequency vibration, steering pull, and reduced traction in turns or under braking; it can trigger ABS/ESC interventions and increase stopping distance. Load path & suspension stress: The 18" low-profile package leaves little sidewall cushion. On normal bumps/potholes, impact energy transfers directly to the wheel. Repeated “bottom-out” events may damage shocks/struts, alignment, and tires, compounding instability. Repeatability & foreseeability: Two events under ordinary use within a short interval indicate a systemic integrity problem, not random abuse. Requested resolution: A no-cost remedy: (1) replace all rims/tires with more durable parts and inspect/repair suspension; or (2) provide comprehensive wheel/tire protection and repair damaged rim; or (3) exchange he vehicle for a comparable model with no issue
