The U.S. Senate's Commerce Committee report on Takata airbags failures says the company stopped safety audits between 2009-2011 for financial reasons. At least 8 deaths and 100 injuries have been reported from faulty airbags which rupture and spray shrapnel when they fail in vehicles as a result of propellants degrading over time. The report cites problems on the manufacturing lines revealed in emails inside the company. This has led automobile companies to fix the problem in 34 million automobiles, in the largest ever recall in the U.S. The Senate report also says the regulators at the National Highway Traffic Safety Administration (NHTSA) were slow to respond. The Transportation Department inspector general's report is critical of regulators at the NHTSA. Takata and 10 automakers are conducting separate investigations for root causes.
