Plugs for brake/running/turn signal lights have moisture and road salt inside and corrode causing brake/running/turn signal light to not operate. I have cleaned the corrosion out multiple times, now the contacts inside the plug have corroded away with the only resolution being to replace the wire harness. Parts are available for inspection. My safety and the safety of others is at risk due to failure of lights to operate. I have not contacted a dealer or service center. I have diagnosed the problem myself and will repair myself when i receive the new wire harness. I have several other individuals who have experienced the same failure as described.

Headlight projection are horrible and unsafe. I do a lot of night driving on poorly lit and unlit streets both in neighborhoods and in wide open areas. Driving through rain on poorly marked roads. These lights do not shine far enough nor wide enough. I thought there were safety standards to meet, but there must be none or GM just didn't meet them. Been this way since new so I'm not sure what to put in the date below.
