2022 BUICK ENCLAVE Electrical System Problems

I have been the owner of this vehicle almost 6 months. My headlights and brake lights do not currently work because of what was diagnosed as electrical failure at the Buick dealership. There are no warranties for this issue specifically aside from the 36,000/3 year warranty which is expired. The dealership mechanics don’t know how to fix this issue and informed me it could be thousands. It poses an extreme safety risk and prevents me from being able to drive my car at any point requiring headlights. I’ve been given a warning from an officer as to my lights being out as it gets dark around 5-5:30 pm. This vehicle hasn’t been altered in any way and has all original manufacturer parts. It has not been wrecked or in any minor or major accident. I am stuck with a “LEMON” but in the state of SC my vehicle doesn’t qualify....
