If you own a 2011 or 2012 model-year Nissan Versa, you may want to start shutting your doors more gently. The National Highway Traffic Safety Administration launched an investigation into airbags that could deploy when doors are closed.

The investigation began after NHTSA received early warning reporting data from Nissan and three complaints concerning the issue, which involves side curtain and seat-mounted side airbags. No deaths or injuries have been reported so far. If NHTSA deems a recall necessary, 155,000 cars could be affected.
