I have owned my 2011 Acadia since it was new. I have had minimal problems with the vehicle; however, over the past year I have had to change the headlights 3 times. They keep burning out. Several days ago, while on the highway, the went out at the same time causing a very dangerous situation. To make it worse, the lights are extremely difficult to reach. It takes approximately 20 minutes to change one bulb. I have contacted the dealer, but they were unable to provide a reason or solution. Internet searches have revealed similar issues. How do I make it stop...
