Consumer information on vehicle safety and recalls can be found at SaferCar.gov. The site is part of the National Highway Traffic Safety Administration and offers several databases. Search for vehicle recalls/defects or child restraint recalls. A relatively new feature is the RSS option to receive notification of new recalls.
Obtain crash test and rollover information from the homepage of SaferCar.gov. However, more detailed crash test data can also be found at NHTSA crash test database, which contains “engineering data measured during various types of research, the New Car Assessment Program (NCAP), and compliance crash tests.”
