I bought my car new on June 30, 2008. In the fall of 2011 I noticed that one of the rear door locks would not actually unlock when using the fob or the unlock button on the inside of the car. Now in June 2012 - neither of the rear doors will unlock unless someone is physically in the car. I have two small children - both in child safety seats and both in a harness, one is still rear-facing. To unlock the doors I either have to put my child in the front seat, lay the drivers seat down, unlock the back door, move her to the back seat and crawl across the car to unlock the passenger door (where the rear-facing seat is located) or my oldest has to crawl through the front and then unlock both doors for me. I called to see how much it would be to fix the issue and was told almost $300 each. I called GM to see if they could assist me and was told that since I was outside of the factory warranty it would be a "wear and tear issue" and the customer was responsible. They offered no assistance. This is a huge safety concern because there would be no way to access both harnessed children in the event of an emergency other than breaking the windows in their faces. I am very frustrated and do not know what to do at this point.

Door locks fail to work with remote had one replaced in 2010 for the back door under warranty. Now the other side went with only 30000 miles. Warranty is up and it's a hazard because I have to pick the latch up, on the door before I can open it. It's hard for child or older person to do in an emergency. Why should I have to pay a GM dealer to tell me the lock is no good. I think there should be a recall.
