On September 17, 2026, my 2018 Nissan was involved in a severe rear-end collision on a freeway. The vehicle sustained extensive damage and was declared a total loss. None of the airbags deployed. I am concerned that the airbag/SRS system may not have functioned as designed. After the collision, I observed exposed components in the severely damaged rear area. I cannot confirm whether these components were part of the airbag or crash sensor system. Immediately after the collision, I believe I may have briefly seen an airbag-related warning or message on the instrument panel. I was shaken after the crash and cannot confirm the exact message. I experienced back pain, mild dizziness, and a nosebleed following the collision and subsequently sought medical treatment. The crash was documented by the California Highway Patrol, and the vehicle was also inspected/documented for the insurance claim. The vehicle has not, to my knowledge, been inspected by Nissan specifically for the airbag/SRS issue. I am requesting an investigation into whether the airbag/SRS system functioned properly during this collision.
