infotainment nav screen brightness failure

  1. The screen will not go into night mode when it is supposed to, and to make matters worse, there does not appear to be a way to fix it. The screen is so incredibly bright at night that I can turn it off, or lower the brightness controls to the point that all other gauges are almost dark in order to just be able to see my NAV screen.

    2. A similar issue with the back up camera, as when it is engaged it will be far too bright, switching from mirrors to the camera is rough on the eyes, and if there is dirt on the camera, or water, then forget it, the screen will just be washed out with the brightness. If that were not enough, for a split second when the car is placed in park from reverse, the brightness goes back to normal before it turns off.

    3. The auto start-stop, most people hate it and know that the auto makers are just abusing the test cycle to push this garbage on the people, but the one on this car is worst I have ever seen, it stops when it shouldn't, and does not seem to want to start when it should have. It actually scares me sometimes when I need to hustle and it wants to delay my acceleration. It is not large amount of time with the delay, but its just enough to annoy and possible hurt someone.

    This car is really nice, and for the price I got it as, seems to be one of the best deals around for the features offered, but these three simple issues have killed it for me, so much so that after only 7 months I want to trade it in and never consider another GM car again, its that bad.
