Volvo: warning lights and lights went out while driving, volvo v70, sweet answer

Question
While driving my 2004 Volvo V70 (normal speed/road conditions etc) the warning light "rear left door open" came on and the wipers went on once. I pulled over and checked the door (have 3 children in the back row) but it was closed. I kept driving. About a half mile later, same message and wipers went on again once, together with all the inside lights. I slowed down a little. Then the message came "brake failure" and 30 sec. later all the lights went out, inside the dashboard, the headlights, etc. I used the breaks, went to 10 m/h speed. No strange noises etc. I stopped, turned off the engine. Started the car again and got the message: "SRS airbag, urgent service"

I was able to drive to car back home, still with the last message and a orange light (not red anymore)

Any idea what this is/was/might have cost this problem? Any idea about a solution?

Thank you!

Answer
Dinie,
Cost and the solution will depend on what is found. Your car will require some fault code reading and inspection. Sounds like an electrical malfunction in the Central Electrical Module, ignition switch, or fuse problem. It might be saveable with a software update. Take the car to the dealer so they can run some tests. Sorry there is not a short and sweet answer, but problems like yours take time and inspection.
