I noticed my rear defrost has quite working. I figured it was a fuse so I wasn't to worried about it. We've had a lot of snow recently and figured I better check my fuses. The relay is working that is located under the hood. We traced to wiring through the fire wall and down to where it comes into the vehicle (down by your feet). There is a wiring there and once we disconnected it we noticed it is burnt very bad. Where the two pieces connect together is melted and is black. This could have been extremely bad if it would have caught fire.

The rear defogger on my vehicle stopped working. Investigation lead to a video on the internet showing a melted connector on the passenger side fuse box. Following the steps in the video I found the exact same burned up connector under the carpet of my vehicle. Photos included. The connector was clearly not designed to handle the current the fuse was allowing to flow through. This is a fire risk as well as an inconvenience as now my rear defogger is inoperative. I never smelled the burning part but lost clearing ability about three weeks ago when driving in cold weather.

After the novelty of my new care wore off, I became aware of the problem of limited visibility when looking out the rear window. The middle headrest in the back seat obscures much of the window! I am extra careful when backing up because of this limited visibility. I am concerned when my kids drive this car because, as you know, younger drivers don't always listen to their parents. In addition, my daughter isn't nearly as tall as I am and the backseat middle headrest is even more of an issue with shorter people. This isn't a defect, per SE, but just an extremely hazardous design flaw. Looking on your website, I am now aware that I am not the only one with this concern. I am glad GM redesigned the 2012 model to take this hazard away but what about for this 2011 model year?
