Court documents filed this week allege that five auto companies were aware of defects that caused Takata air bags to potentially harm or kill motorists but continued to use them anyway to save on costs, reports The Washington Post. The documents claim that Honda, Ford, BMW, Toyota and Nissan have known about the issues with the Japanese manufacturer’s air bags for more than a decade but still used them because Takata was cheaper than its competitors and could produce the bulk quantities the automakers needed, according to the court documents.
