The pre-collision malfunction warning light illuminated. The brake malfunction light was flashing. The air bags did not deploy. There was no reported fire or injury. A police report was filed. The vehicle was taken to the local dealer, who could not determine the failure. The vehicle was not diagnosed or repaired. The vehicle was then towed to an autobody center where it remained.
