I was backing out of my driveway very slowly as usual. I checked the road both ways several times. A US mail truck evidently traveling at a high rate of speed came up behind me while I was looking in the opposite direction. The automatic braking did not kick in, the warning system didn't work. After the accident the green, yellow, red lines on the camera and the warning beeping stuff-all were not working for several weeks. All of the sudden, they started working. HISTORY-4 days after purchasing the vehicle we have had lane departure, driver assist problems. The passenger window does what it wants. The electric controls for the heat/ac go blank, or can't change settings. There seems to be a huge electrical issue. Every time we've taken the car in for service, the dealership just insults me that I can't drive and they can't find any problems. They seem to have an answer for everything yet the problems persist. Efforts to go thru Subaru are stalled waiting on their response. They were to look at the BLACK BOX during time of accident. We are still waiting. We are frustrated. I wish the dealership had taken the car back after we first bought it like we demanded. I'm terrified this car is going to cause an accident.
