One problem related to air bag not deploy has been reported for the 2019 Mazda MX5. The most recently reported issues are listed below.
As I was exiting a bp gas station (62 griffin corporation dr, chelsea, al 35043) and making a right onto county road 11, the rear tires of the car started to spin (1/4 throttle). I noticed that abs or the stability control system did not activate. The car was not in "sport" mode. It was in the "d" driving mode. The rear tires continued spinning and I felt the car's back end fishtailing. At this point, I started to get on the brakes hard and try to do minor corrections, when I felt that the brake pedal was not pulsating, and the car was not slowing down at all. At this point, I was facing oncoming traffic and the railroad tracks that were about >500 ft in front of me. I look to my right and notice that I am about to slide into the railroad crossing sign. The impact was hard enough to where my right buttock ended up next to the handbrake of the car. My arm is slightly bruised from it being swung to the right and hitting the passenger window. The airbags were not deployed at all. However, the damage done to the car is, left lower control arm scratched/scuffed/damaged, the passenger side mirror broken off, the passenger door dented inwards, the side skirt (the part that runs across the bottom of the car) ripped off on the driver's side and bent upwards on the passenger side, and finally, the passenger side door sill dented/bent inwards. The pictures attached are the photos of my bruise and the incident.
