Takata stopped its internal safety checks on its airbags because the audits were too costly, years before airbags made by the Japanese auto-parts giant were linked to eight deaths and over a hundred injuries, according to a new Congressional report. Emails between top Takata executives in 2011 revealed that "global safety audits stopped for financial reasons for last 2 years," the Congressional report showed. The emails were part of 13,000 documents that were presented to the Senate Commerce Committee, which is investigating Takata's airbag problem as well as the National Highway Traffic Safety Administration response. In 2013, eight people died and 100 were injured due to airbags, which exploded and sprayed drivers with shrapnel.
