The passenger seat occupancy sensor goes off intermittently, causing an extremely distracting seatbelt alarm in the vehicle during operation. This has occurred to me while driving on a highway; I deeply lost focus on controlling the vehicle as the alarm started suddenly, I shoved the one water bottle off the seat to no avail, and I had to reach way over to plug the seatbelt in to silence it. In other instances where this occurs, only a full restart of the vehicle will reset the sensor. Existing TSB 08-001/23 was deemed to not cover my vehicle by the manufacturer, despite my VIN being in range and symptoms being identical.

The air conditioning compressor clutch suddenly would not engage, leading to reduced visibility out of the windshield during humid weather in Oklahoma springtime and extended times for windshield to defog. Temperatures inside the vehicle also rose to very high levels without air conditioning available, even with windows down while driving. No crash or injuries but this presented an unsafe situation for a vehicle with only 39,000 miles and purchased new from the dealership. There were no indicator lights, messages, or warnings, other than observation that air conditioner vents were no longer blowing cold air when selecting the AC button after problem occurred. Problem was verified by both an independent mechanic and our Mazda dealership. AC system was overcharged from the factory per diagnostic results, leading to internal AC compressor short and early component failure.

Airbags failed to deploy in a collision where the front end of the vehicle was crushed, and a driver wearing a seat belt hit the steering wheel with enough force to fracture their sternum and cause two cervical fractures as well.
