We hit a deer while driving at 55 MPH. We were wearing seatbelts and not injured, it was a major frontal impact, the car is probably totalled. When we stopped we noticed multiple warning messages on the display: * restraint system failure * passenger airbag failure * pre-tensioner failure It appears that the car detected the collision and tried to activate the restraint systems, but nothing activated. No air bags deployed, and we did not feel the pre-tensioners activate.
