HIGH BEAM HEADLIGHTS OUT OF ADJUSTMENT LEFT SIDE WAY HIGH AND TO THE LEFT LIGHTS UP TREES NOT ROAD. RIGHT SIDE WAY TO HIGH. PER CADILLAC AND DEALER NO ADJUSTMENT IS POSSIBLE. ONLY ADJUSTMENT IS ON LOW BEAMS, NONE FOR HIGH BEAMS. COMPLAINTS TO CADILLAC WENT NO PLACE. AFTER MANY E-MAILS FINALLY TALKED TO A REAL PERSON AND WAS OFFERED $200.00 OF SERVICE WORK TO GO AWAY, I TURNED IT DOWN, PER CADILLAC THEY WOULD NOW CLOSE MY COMPLIANT OUT. I DRIVE ON COUNTY ROADS, TWO LANE FARM COUNTY AND THE HIGH BEAMS DO NOT LIGHT UP THE ROAD AHEAD OF MY CAR, ONLY TREE TOPS TO THE LEFT. PER CALIF LAW ALL HEADLIGHTS MUST BE ADJUSTED PROPERLY, IF NO ADJUSTMENTS IS ON THE HIGH BEAMS IT IS AGAINST CALIF STATE LAW BUT CADILLAC WILL NOT DO ANYTHING TO CORRECT THIS.
