NHTSA Complaint #11703597 — 2010 MAZDA RX-8

Safety concerns of Sam Leman Mazda located in blooomington IL installed a radiator from auto zone instead of using Mazda-approved parts. Sam Lemans modified other vehicle components to make the auto zone part fit and initially suggested using zip ties. My vehicle was held from Nov 5-25, 2025 while the dealership attempted to figure out how to alter components to fit the Auto Zone part - my choices were use the (1) Auto Zone part or (2) supply my own. Mazda corporate was then involved due to the unnecessary vehicle modifications due to Sam Lemans using a non approved Mazda part (Auto Zone radiator). Sam Leman compromised safety & my vehicle has been compromised due to component alternations and non Mazda approved parts. The auto zone part was not designed for my specific car and could fail during normal driving conditions. By altering the fan housing to make the unauthorized Mazda part fit, Sam Lemans created a risk of mechanical failure or accident. I am have a video showing the dealership discussing “zip tie” repair to hold the weight of the radiator (but this site will not allow me to upload a .mov video for your review only a photo of the video is there an alternate email I can send the video for review of Sam Leman’s mechanic discussing using zip ties to)? I am requesting NHTSA review this as a safety risk due to the wrong part, alteration of other parts, and non mazda approved part used by an authorized Mazda dealership, even after Mazda corporate was notified.
