Air Bag Light On problems of the 2006 SAAB 9-7x

While driving home our headlights flickered and turned off. I was able to pull over and restart the vehicle and the headlights came back on. Once driving again, they flickered and the passenger side headlight went out. I was able to drive the vehicle home with the one light (luckily). When I went to replace the headlight, it was back on again. I checked all connections and was unable to find the cause. A couple of weeks later the stabila-trac system light and air bag light came on and went off (5 min period). A couple of days later the steering locked up and would jump, we brought it to the SAAB dealer and they had to replace the awd actuator needed to be replaced ($788). We replaced it and the steering and awd system appeared to work fine. Two days later the airbag light and stabila-trac system light came on again and went off. Dealer was unable to pull up the codes (not logging codes?). A month later while driving, the windshield wipers would come on and turn off on their own and when their on the washer sprayers for the headlights and windshield turn on on their own. This vehicle has major safety issues due to electrical issues and should be investigated. This vehicle has become unsafe and untrustworthy.
