2016 GMC Acadia 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 hours, all daylight they never could see it at night. We had to get it readjusted back to where it was just to see again but back to still no good. I started researching to see if others are having similar problems and it does look like there are many complaints about loose wires in the headlights & fuse box, or maybe something related to the computer? Some other years may have had a recall for this same problem. I really hope someone like you could investigate this. My husband is a retired state trooper and ready to get rid of this beautiful car just because the headlights!! We live in the country and our son is worried he will get in an accident or hit someone walking down the road at night because he can't see. A mother and son shouldn't have to stress about headlights/seeing at night/crashes when we have a nice car!! How do both headlights need replaced 3 times on the same car?? We are trying to see if they make LED lights for this model but were told no. Any advice to have GMC help us with this before something happens? I would feel terrible if we could prevent something but just selling it and passing the problem on doesn't seem the answer to me. Thank you
