On 12/09/23, my 2024 Mazda CX-90 PHEV, purchased on 11/11/23, just got out of the driveway to make a left turn around 500 feet from the driveway when there was resistance in turning the steering wheel left, causing vehicle to swerve to the right and hitting the fire hydrant on the side of the road located just around the corner. Both airbags deployed causing extensive damage to the passenger front side of the car. The automatic emergency braking did not engage to avoid collision with the fire hydrant. One of the passengers suffered avascular necrosis of the hip as a result of the accident. The vehicle was towed to a collision center, then towed to the Mazda dealership, but according to the dealership, no inspection report was available in their system as of 03/19/24. The insurance company declared the vehicle a total loss. …

The wrong image stayed displayed despite turning the car off and back on multiple times.
