“I was driving at nighttime and my head lights cut off.. they were in auto light mode. I read that gmc knows about some sort of issue with this but only covers repairs up to 150k miles. My car is 156k miles. There was no warning lights and no indication anything was wrong. Luckily I was the only care on my side of the highway and was able to slam on the brakes and come to a complete stop. I turned the car off and then turned the head lights to manual and they can back on. …”
