First incidence was 11/22/2018 headlights did not function nor did taillights. Manually turned them on; yet was pulled by Ga sheriff for no headlights, who escorted me to my hotel.

warning lamps or messages until this last time when we were almost killed on Lookout Mountain in Al, on 5/9/2023. It was 7:23pm it was raining & the headlights went out, as did the dash lights & OnStar. This stretch of mountain is known as "Joe's Truck Stop;" because so many 18 wheelers have wrecked on this stretch of road. At the first pullover I stopped, cut car off, then restarted it & a message error was on the screen. The lights came on automatically, OnStar restarted & everything worked fine. I had just had the vehicle in my local dealership for the same issue & had it inspected, & no issues were found! This is why I don't drive this vehicle after dark & why it only has 18,000+ miles on it. I paid over $45,000 for a vehicle I can't enjoy & I could be killed & no one would know why; therefore, if I don't get some answers I'm going public. My Buick Enclave can't be the only one with this malfunction.
