2016 GMC ACADIA Exterior Lighting Problems

A few years ago I was driving home and both headlights of our GMC Acadia went out at the same time. I drove home, in the country, in total darkness. We had them replaced by the garage, which was very, very expensive due to extreme difficulty accessing the headlights for this model. Since then, we have had to replace them two more times which we did ourselves due to the cost. We have owned this car since it's been brand new and have always had issues with seeing in the dark. For the last several years, we have had teen drivers driving this car. My son is worried so we recently we had it in the shop to adjust the headlights. They actually made them worse, which we didn't think could happen. They said they had their best mechanic on it but because they were doing it during their office...

Recently the "Service Side Detection System" light came on. Now the blind side monitoring doesn't work. While driving all of lights on the dash, radio, and headlights turned off. I was unable to see the road, my speed, or anything within the vehicle. I did some research and this is a vary common issue with these vehicles and nothing has been done to correct it.

2016 SLE GMC ACADIA CENTER GEAR SHIFTING COMPONENT LEVEL DOES NOT INDICATE WHAT GEAR THE VEHICLE IS CURRENTLY IN. P,R,N,D,L ALL REMAIN WHITE IN COLOR DESPITE BEING IN A DIFFERENT GEAR; AN IMPROVEMENT (PERHAPS A COLOR CHANGE TO THE CURRENT GEAR) IS NEEDED. GEAR INDICATION IS CURRENTLY LOCATED ON A 2 INCH BY 3 INCH SCREEN SCREEN ABOVE THE SPEEDOMETER IN THE INSTRUMENT CLUSTER. HOWEVER, THE STEERING WHEEL IS LOCATED WITHIN THE AVERAGE PERSONS FIELD OF VIEW OF THE INDICATION SCREEN, THUS MAKING THE INDICATION SCREEN USELESS UNTIL A MAJOR BODY ADJUSTMENT, UP OR DOWN, IS MADE. POOR INDICATION OF CURRENT GEAR AND THE SIZE OF GEAR INDICATION NEED TO BE DRASTICALLY IMPROVED TO PREVENT ACCIDENTAL GEAR SELECTION WHICH WOULD RESULT IN WRECKS AND LOST OF LIFE.
