Are you driving a car with dangerous airbags?

The U.S. government recently issued an immediate recall for more than 4.7 million vehicles that were installed with defective airbags. However, the consumer website that lists vehicle identification numbers included in the recall did not appear to be working on Tuesday.

On Monday, the National Highway and Transportation Safety Administration urged U.S. owners to look up their vehicle identification number to see if their car or truck was featured in the recall.

According to the recall, the airbags contained a potentially fatal flaw and were made by Takata, a Japanese automobile parts manufacturer. Once deployed, the faulty airbags have released metal shrapnel during crashes that has led to the deaths of at least four people, CBS News reported.

The affected automobiles include several models of Toyota, Honda, Nissan, Mazda, BMW and General Motors and were sold within the United States. The NHTSA recall alert noted that consumers in Florida, Puerto Rico, Guam, Saipan, American Samoa, the U.S. Virgin Islands and Hawaii needed to be particularly aware of the risks with these airbags.
