3X the driver window button is inoperable. Would turn off car and then it would again work. The worst issue is this: Started up car this morning 7-9-12 (this is the 3rd occurrence) and the doors do not lock, then I put it in reverse and it goes about 2 feet and it applies the brakes. I noticed each time the gear console does not light up. The car actually does not go into gear. Each time I have turned off the ignition and restarted it and it works fine. It's going to the shop for the 30K check up and this will be brought up. The drivers window has been brought up and the dealer has said there was no problem. Wrong. There is when it doesn't work. I had one of these in 2001 and it too had electrical issues. My neighbor just sold their 05 Sonata due to electrical issues.
