Headlights Turn Off While Driving problems of the 2009 Chevrolet Traverse

We have had multiple issues with the 09 chevy Traverse. The check engine light came on so we ran test on it. The test came back that there were 4 sensors that went out. We went and purchased those 4 sensors and reset the computer and within an hour the check engine light was back on for those sensors. We then went and replaced the sensors once again and the same thing happened. The next thing that happened was the headlights went out while driving down the road. Changed both headlights and a month later they went out again. Only way to help this issue was to turn off daytime lights. About 2 months ago the ac unit just stopped working while driving down the highway. Thought the ac might need recharged so we recharged it and it worked again for about an hour. Now it will not even allow you to turn the ac on at all. Just a couple of days ago I was driving down the interstate when the check engine light flashed and the car stated check engine soon then the traction control light came on and the car read that stabilitrak was off. All of these issues have occurred over the last year and I have only owned this car for 2 years and it only has about 128000 miles on it. I could expect theses issues if the car was a lot older but I do not feel safe driving this car because of all the issues that keep occurring. Very disappointed in the Traverse because I know I am not the only one with these issues but there is nothing that the dealerships will do to help except charge me a lot to fix the issues again only for them to keep messing up.
