The rearview mirror fell off when I lightly knocked with my sunshade. The Mazda dealership reattached the mirror when the car was in for an oil change. But then a year later, the same thing happened. I took my car to get an oil change at our regular mechanic and they re-attached the mirror, but then it fell off in my hand a week later when I tried to adjust the mirror. I took the vehicle back to the dealership to get the mirror reattached and they quoted me $105 to reattach the mirror. From my research on YouTube and Reddit, this is a common flaw of Mazdas and I do not believe I should have to pay to reattach a rearview mirror. I tried to reattach it myself, after watching YouTube…

While attempting a left-hand turn, the steering wheel suddenly became stiff and unresponsive, as if the mechanical gear had bound. This sudden resistance made it impossible to complete the turn, causing the vehicle to strike a curb at low speed. A post-accident inspection at Lee Johnson Mazda (RO# 649854) confirmed extensive damage, including a bent inner tie rod, a damaged front wheel bearing/hub assembly, and wheel/tire damage totaling over $6,500. The dealership stated no electronic fault codes were present in the computer, but the physical behavior matches the 'sticky steering' symptoms currently under federal investigation for other Mazda models (Recall 24V022 / RQ26002). I believe a…

My 2023 Mazda CX-30, which is currently under full manufacturer warranty, was brought to the dealer on October 10, 2025, specifically to address a safety defect involving white chemical particulates blowing through the HVAC vents.
