Airbags did not deploy when vehicle hit 75 ft highway guardrail driving over 70 mph. The car was totaled, the driver's head hit the steering wheel, requiring stitches. EMS and police at the scene were surprised to find airbags not deployed. Vehicle has been inspected by insurance. Manufacturer has not yet been informed, to my knowledge. There were no warning lights or messages indicating a problem with airbags or anything else for that matter. Driver was wearing seatbelt.
