This is already related to Mazda's recall #23V-275 BRAKE PEDAL TRAVEL CONCERN. My car was already involved in crash which I firmly believe that it was related to the brake pedal issue since the brakes didn't hold off the car and the brake assist system was never activated during the accident. Mazda is claiming that my ABS system serial number is a good part, and their dealership claimed that the problem couldn't be reproduced after they held the car for 11 days! I made several attempts to contact Mazda USA but I am not getting tractions for weeks.

On that day at 13:33, while maneuvering into a parking spot in the parking garage with my foot on the brake pedal, the car suddenly and rapidly accelerated and collided with a …

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 …
