2015 GMC Yukon driver assistance complaints

My new, 2015 gmc denali is equipped with a backup camera and the quality is so poor at night, as to make it nearly more dangerous to use than to ignore it. I have had 3 prior gmc denali automobiles. The most recent was a 2011 which was traded in for this new one. The quality of the backup camera in the 2011 model was excellent. My wife and I immediately noted on the new car that the camera image was so blurry and poor resolution at night, we could not safely use the camera to back out of our gated driveway. In the daytime, the image is blurry as well, but usable. Gmc has had the car twice for service and we have complained to gmc corporate and all we get is a statement that the "system is working normally" which is difficult to accept. The federal safety agency's own statistics show that each year approx. 20 people die and 15,000 are injured due to backup incidents. Their guidelines state a camera needs to display (clearly I would assume) a 10 x 20 foot zone behind the vehicle. At night, you cannot see 20 feet clearly behind this vehicle, even in a well lighted street. I am convinced that this poor quality system is going to cause accidents if it has not done so already. Gmc has an obligation to address what I believe is a sub-standard quality image. They cannot defend the fact that the image is much worse than older models of their vehicles. Fortunately, the new denali model does have a sensor system that provides a vibratory warning if you are about to contact an object, but obviously the driver needs to see clearly behind them, before they are about to strike an object in their path. I am hoping your agency can contact gmc to help motivate them to address this issue and improve the safety of their vehicle(s) before the defect contributes to an unnecessary injury or death. In the meantime, we do not use the screen image at night. Thank you.

The new 2015 vehicle freezes up in full time 4wd mode and will not shift out. The dealer indicates that it is a "known problem by gm" and that they are "working on it". Their fix at this point is to have you run the vehicle in 2wd mode which is an obvious safety issue during our winter months as it is then a rear wheel drive vehicle being driven on icy roads.the other fix is to run it in 4wd mode but turn it into 2wd mode every time you turn the vehicle off. Obviously, many drivers will forget to do this and therefore my family at times is just running it in 2wd mode thereby incurring a risky driving situation. Despite numerous discussion, I have not been able to get any information on when the vehicle will be fixed.
