Beginning with 2014 models, side torso airbags became standard for rear seat occupants (they were optional in 2010 - 13 models). (iihs.org)
Known today as airbags, this option provided protection for front seat occupants in the case of a frontal collision. (en.wikipedia.org)
The front passenger seat occupant detection mat that determines if and how the passenger frontal air bag should deploy in a crash may fatigue and develop cracks which could lead to a system failure. (cars.com)
