One problem related to underbody shield has been reported for the 2007 Toyota Prius. The most recently reported issues are listed below.
The car was involved in a collision north of san antonio, texas. The collision ended up being a total lose of the vehicle due to the frame being split, firewall bent and a broken windshield. My concern is the airbags did not deploy. The airbags not deploying with an impact of this nature could increase the likelihood of injuries. I believe a failure of safety equipment of this nature should be investigated to prevent possible future injuries or fatalities.
