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.
