I own a 03 plate Citroen C3. Last weekend, when in the middle lane of the M1 at approx 65-70 mph, my drivers side airbag deployed without warning, forcing my right arm across the wheel making the car swerve into the next lane. I managed to control the car across the carriage-way and bring it to a halt on the hard shoulder. Apart from being bruised by the bag and badly shaken up, both myself and the front passenger were unhurt. We were fortunate that the motor way was quiet at the time-being late at night: had it been busier the consequences would have been fatal. There was no impact to cause the airbag to deploy. Anyone heard of this before or got any advice what to do now? Currently waiting on an experts report...
