(WASHINGTON) -- The National Highway Traffic Safety Administration (NHTSA) is stepping up its investigation of the faulty airbags that resulted in the recall of more than seven million vehicles.
NHTSA Deputy Administrator David Friedman said Thursday that the agency is, "compelling [airbag manufacturer] Takata to produce documents and answer questions under oath relevant to our ongoing investigation into defective airbags they have produced."
The Detroit News reports that Takata must provide those documents by Dec. 1 or face fines of up to $7,000 per day.
The airbags are blamed for at least three deaths and over 100 injuries; in some cases, the canisters holding the bags reportedly shattered as the airbags inflated, sending metal fragments hurtling towards victims. Friedman said he expects the company's "full cooperation."
