Our 2011 Terrain SLT has just over 5,000 miles on it. We have witnessed a really strange electrical "event" with the Terrain on three separate occasions. The first time, I tried to start the car with the remote start and noticed that nothing was happening. So, I went out to the car and noticed that it would not unlock the doors with the remote. I opened the door with the key and the car was completely dead. Not even the Onstar SOS button worked. I tried putting the key in the ignition and it would not start. It would also not release the key from the ignition. Within 10 minutes, the car just turned back on and I was able to start it. But I noticed the clock on the radio moved ahead two hours and the DVD system would paly audio, but there was no picture on the screens. About two hours later, the screens started working again. This has since happened two more times. The DVD system was not affected the other two times. But, again the car was completely dead. What is going on? Anyone else have this issue? ???
