NHTSA Complaint #11524069 — 2017 BUICK ENCLAVE

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. Put car in the shop on 11/24/2018 for diagnostics. Nothing found. Lights have continuously malfunctioned for the last six years and the vehicle has been in the shop & the problem can't be reproduced! The issue has become worse to the point the lights will not always come on when manually turned on & they will go out. There are no 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.
