On October 13th 2025, we were involved in a serious collision while driving our 2018 Hyundai Tucson. The vehicle was struck from behind and spun into a semi-truck, totalling the vehicle. Despite the forward and lateral collision to the semi-truck, no airbags deployed at all during the accident. This resulted in the Tucson driver striking his head on the steering wheel. Our 5-month old son was also on-board the vehicle in his car seat. While everyone walked away from the accident, both adults passengers had whiplash/minor neck injuries that could have been mitigated by airbags deploying. We have serious safety concerns about Hyundai's airbags because of this incident.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Hyundai Tucson Fuel Cell verdict →
