I totalled my car. The steering wheel airbag failed to inflate

I recently rear ended a car and the front of the vechical was damaged. The air bag censor was destroyed, however the airbags did not come out. This was on a 2018 Ford c-max. Many people pointed out this malfunction and how my life was put at risk.

THE RIGHT-HAND OUTSIDE REARVIEW MIRROR CONTAINS A SMALL INSET MIRROR INTENDED TO PROVIDE A DIFFERENT ANGLE OF VIEW SO AS TO GIVE THE DRIVER VISIBILITY OF VEHICLES ALONGSIDE OR IN THE "BLIND SPOT." IT IS SUPPOSED TO BE MOUNTED AT AN ANGLE RELATIVE TO THE PLANE OF THE MAIN MIRROR SIMILAR TO THE DRIVER SIDE MIRROR, BUT ON MY CAR IT IS MOUNTED IN THE SAME PLANE AS THE MAIN MIRROR SO THE VIEWS ARE IDENTICAL. FORD DEALER'S SERVICE MANAGER SAYS IT'S CORRECT, BUT EVERY OTHER FORD VEHICLE I HAVE SEEN HAS AN BLIND SIDE MIRROR THAT IS ANGLED. FORD'S CUSTOMER SERVICE CONSULTANTS REFUSE TO DISPUTE THE LOCAL DEALER'S OPINION. I BELIEVE THIS MIRROR WAS MANUFACTURED AND INSTALLED IN ERROR. FORD'S OWNER MANUALS FOR VARIOUS MODELS ALL DESCRIBE THE BLIND SPOT MIRRORS IDENTICALLY, BUT MY MIRROR DOES NOT CONFORM TO THOSE DESCRPTIONS. MORE CRITICALLY, IT DOESN'T PERFORM ITS INTENDED FUNCTION.

FUEL/PROPULSION SYSTEM

Recently, there has been a whiff of gasoline around my garage but there is more than one vehicle in there so I didn't figure out what the culprit was for a while. After completely filling up my car 9/3/2022, I parked it in the attached garage and in minutes my whole house smelled like gasoline. So I immediately parked it outside and ventilated the house. I took the car to a local shop and they said yes there's a gas odor but they didn't want to touch the repair because it's a hybrid. So all this time later on 9/14/2022, the Ford dealership saw the car and stated that it requires immediate repair and park it outside while we wait for parts. My C-Max has always gotten regular normal maintenance like oil changes and brakes, it got new tires recently. There was one major repair Ford did when the car was assembled incorrectly at the back hatch hinge seal so water was pouring into the circuit board and the battery compartment which screwed up the electronics, and the touchscreen needed replaced, but that was over a year ago and the car has been ok since. It has never ever been wrecked beyond little dings like shopping carts. It makes absolutely zero sense that the car would require this major repair at 82830 miles, and it's going to cost me $2400 which blows my mind. And it's dangerous! Now it has the doom vibe of a Pinto. I am extremely concerned for other C-max owners.
