2021 Mazda MAZDA3

My car started to show a warning on the dashboard that the airbag system is malfunctioning. The alarm would come on for a few seconds, then turn off, then repeat like that multiple times every drive. At the time it started, my car had less than 500 miles on it, and it continued after that until I got it fixed. I took it to the Mazda dealership where I bought it, and they said it was a short circuit to the driver's side airbags. They told me that could have caused the airbags to deploy prematurely or not at all in an accident. I am also a part of a Mazda 3 community and am active on the forums, and in the last month I have seen at least 30-40 other 2021 Mazda 3 owners also report the same exact error code, with the same short circuit issue being cited as the problem by the dealership. Parts are on backorder for weeks for most of these owners, and some of them were told by the dealership to keep their car while they waited for the part, whereas my own dealership told me it was unsafe to drive the car and to have it towed to the dealership instead.

Context: ADAS was not on. Lane keep assist is disabled in system settings entirely as it is dangerous. Blinkers were on, I was pulling out from parallel parking into left turn lane onto a straight road with slight incline. Car is of the Turbo trim on stock tires. Upon finishing pulling out of parallel parking spot and gassing the car, torque vectoring or some underlying collision avoidance may have phantom activated. I felt torque shift to the wrong tires, unsettling the car, and the wheel -- with no human input -- jerked to the left to force me into the lane left of intended. I applied throttle and steered right back into the correct lane, but the car was applying torque to the wrong tires and applying a left bias to the steering. Only after I got above 25mph and held straight did the car settle. Almost caused an accident if the lane was not empty due to car unsettling itself into the left lane.

I had two incidents during a short 25 min drive. Incident 1: I was in right side of the road, there were 2 lanes on this side. I was in the far left lane driving at below 30 mph, there was no vehicle directly behind me, and no vehicle directly in front of me. There was no vehicle in the oncoming side of traffic. There was 1 vehicle in the right lane next to me, about 20 feet behind. This vehicle slowed down to turn right into a parking lot. I did not have my foot on the brake at all, the vehicle behind me was in no way veering into my lane or doing anything abnormal. At this point, all of a sudden my car hard braked automatically. I had not touched the brake and I was driving straight and not veering. It was very sudden, and very hard braking, and it jerked me in my seat because of how hard the brake had suddenly turned on. Incident 2: After that first incident, there was a second time when this happened on the same trip. Once again, this time I was driving at about 35 mph. It was again where there were two lanes on my side of the road and I was in the left lane. No vehicles were in front or behind me. In the right lane next me to, there was 3 vehicles in a row about 25 feet behind me, and the front vehicle of them stopped to turn right into another parking lot area. The same thing happened, I did not have my foot on the brake at all, and had not veered at all and was driving straight. The brakes automatically came on suddenly in a very hard brake, resulting again in a sudden complete stop, even though there were no cars in directly in front or behind me. The vehicle was brought brand new at the dealership , so I had no cause to have the brakes inspected by the dealership, police, or insurance company. There was a warning that the safety features had been disabled due to obstruction of the front sensor, but there was no warning lamps that the emergency automatic brake was going to be used, it just happened.

The error code "B14FO-76 FORWARD SENSING CAMERA DEVIATION - WRONG MOUNTING POSITION" was discovered, and verified, by a Safelite Auto Glass service center when the 2021 Mazda 3 was in for a repair (stone chip) to the windshield on September 21, 2021. There were no warning messages nor lights to alert the driver as to the improper installation/mounting of this device. There has been no known modification to nor obstruction of the FSC -- its condition is now as it was received new from the dealer. Improper mounting ("Wrong Mounting Position") of the Forward Sensing Camera affects multiple safety systems of this vehicle, which affects the safety of the vehicle's passengers as well as everyone's safety around the vehicle every time it is driven -- there's no telling what injury and damage may occur from an errant un-commanded driving tasks such as emergency braking and faulty lane departure corrections.
