I was driving to work in my 2022 Ford Bronco Sport when traffic ahead of me stopped suddenly. I was able to come to a complete stop. The vehicle behind me did not see the stopped traffic until the last second and rear-ended my vehicle at an estimated speed of approximately 50 mph. The impact was severe enough that my vehicle was pushed forward into the car in front of me, resulting in a multi-vehicle collision. Despite the severity of the impact, none of my airbags deployed. My vehicle sustained significant damage and was declared a total loss. I sustained serious injuries in this crash and continue to experience long-term, life-altering effects. Given the force of the collision and the extent of the damage, I am concerned about why the airbag system did not deploy and whether there may be a defect in the airbag or crash sensor system. I am submitting this complaint so the incident can be reviewed and investigated to determine whether this presents a broader safety issue.
