2015 BUICK ENCLAVE Exterior Lighting Problems

I had storm damage to my vehicle and needed the front headlight replaced. This was a insurance claim and it went to a local body shop as well as a GM Dealership trying to fix the problem. My vehicle is equipped with Adaptive Forwarding Headlights that turn with my steering wheel. Once my headlight was replaced this feature cannot work again. This feature is what holds my headlights in alignment with a module behind the headlight. GM is aware of this issue, and they cannot fix it. Now I have headlights that will not stay in place.

AIR BAG AND SIDE DECTION LIGHTS BLINK DON'T WORK AND HEADLIGHT DON'T WORK AND CAR STOPS RUNNING WIPERS ONLY WORK ON HIGH WATER POURS ON MY FOOT WHEN IT RAINS HAS TO IN TO SHOP AGAIN TOMMROW GAYLORD MICH

SERVICE SIDE DETECTION SYSTEM . SIDE AND REAR ALERTS DO NOT WORK. NOTICE COMES UP ON DASHBOARD EVERY TIME I START THE CAR. HAPPENED 200 MILES AFTER WARRANTY IS OVER AT 50,000 MILES.

BATTERY HAS BEEN REPLACED TWICE IN 20 MONTHS DUE TO FAILURE OF CHARGING SYSTEM TO RECHARGE BATTERY. TURN SIGNALS DO NOT WORK PROPERLY OR AT ALL. DEALER SAYS BATTERY IS "DEFECTIVE". LOW ENGINE RPM TO INCREASE FUEL MILEAGE AND AUTOMATIC ILLUMINATION OF DRIVING LIGHTS END UP TO BATTERY BEING IN A CONSTANT DISCHARGE STATE LEADING TO FAILURE. SIGNAL LIGHTS WILL SLOW DOWN OR STOP ALTOGETHER WHILE SITTING AT A STOP LIGHT. THE VEHICLE HAS LEFT ME STRANDED SEVERAL TIME BECAUSE IT WILL NOT RESTART - THERE IS NO WARNING THAT FAILURE IS IMMINENT. POOR DESIGN IN ONE SAFETY FEATURE LEADS TO A FAILURE OF ANOTHER SAFETY FEATURE AND EVENTUALLY TO FAILURE OF THE VEHICLE ALTOGETHER. THERE IS NO VOLT METER AND NO WARNING LIGHTS ARE EVER ILLUMINATED.
