NHTSA Complaint #11656370 — 2024 MAZDA CX-90

On multiple occasions the vehicle has falsely detected collisions and suddenly braked while on highway leading to serious safety issues. On other occasions, while changing the lanes with blinkers on, the vehicle suddenly steered back into the original lane and triggered a collision warning even though there was no vehicle/obstacle nearby. This created a serious risk of collision. Even at slow speeds, the vehicle inaccurately triggers a collision warning creating unsafe driving conditions. This frequently happens when we are driving the vehicle in the parking garage, even in absence of moving vehicles nearby. The mild hybrid power train system had issue leading to hybrid system malfunction and iSTOP malfunction. This finally led to hybrid battery failure and the vehicle remaining out of service for over a month. Apple Carplay disconnects erratically creating hazardous condition especially when we are using Carplay for navigation. Such a disconnection requires the driver to suddenly reach over to the phone and input driving directions in the phone again. This is especially dangerous in city driving conditions needing frequent turns.
