I was driving on a residential street, going no more than 25 mph with my two two year olds in their car seats behind me. Suddenly and simultaneously, all four of the side airbags deployed (front and back), knocking my girls seats together, the front right side of the car dropped down and started grinding on the wheel. I was able to pull off to the side of the road thankfully. I turned the car off, and when I got out to look at the front, the car door shut, and for the first time, automatically locked me out, my kids inside, with its own key and my purse as well.
At 55 mph on a slippery right hand side curve (speed limit is 65 mph) vehicle under-steered and lost traction completely, without touching the brakes, it started to slow down and skidded to the outside of the curve (to the left). I tried to get it back to the driving lane, it started to skid laterally to the right and slowed down until it hit a reflector post on the edge of the right lane and stopped. Vehicle information on the dash board read "ice detected. . . ". Although the damage on the right door was a very minor dent, the car deployed all 4 head curtain airbags and 2 right side airbags, engine was shut down and front seat-belts were stuck. Few minutes later, the engine ran normally with the "ice detected . . " message still on. It seems that the airbags sensors were activated for no required reason for a minor dent on the door. Also, the stability and the faulty braking system might be of a great safety issue on this vehicle.
