NHTSA Complaint #10990679 — 2017 CADILLAC XT5

I HAVE AN CADILLAC XT 5 2017. THE LANE DEPARTURE WARNING DOES NOT WORK AS ADVERTISED. I HAVE SPOKE WITH SEVERAL PEOPLE FROM THE DEALER TO DEALERS REPRESENTATIVE AND REGIONAL MANAGER. AFTER 5 WEEKS THE REGIONAL MANAGER TOLD ME THAT THE LDW WAS WORKING PROPERLY AS DESIGNED. HE OFFERED ME SOME TYPE OF COMPENSATION ( $300 ). HE AGREED THAT I WAS CORRECT THAT THE WAY CADILLAC ADVERTISED THIS WAS INCORRECT AND THANK ME FOR FINDING IT. HE SAID CADILLAC WILL BE CHANGING HOW THEY ADVERTISE THIS OPTION. WELL GREAT WHAT DO I DO WITH A $ 54,000 DOLLAR I PURCHASE THAT HAD FALSE ADVERTISING. I HAVE HAD LDW IN OTHER GM VEHICLES AND KNOW HOW THEY WORK. NOW TO THE PROBLEM, WHEN I GO OVER THE LINE THE SEAT IS SUPPOSE TO VIBRATE OR HEAR A BEEP. I HAVE TRIED TO HAVE EITHER WORK BUT GOING OVER THE LINE OVER 100 TIMES IT ONLY WORKED 5 TIMES. I WAS GOING OVER 40 MILES PER HOUR AND THE LAW WAS GREEN BUT ONLY ALERTED ME THOSE 5 TIMES. ALSO I WAS ABOUT 6 FEET OVER THE LINE EACH TINE IT WENT OFF THOSE FEW TIMES. MY CONCERN IS WHAT HAPPENS IF I NOD OFF OR FALL ASLEEP AND DRIFT OVER THE LINE AND I HIT THE CAR, CURB, TREE OR TELEPHONE POLE. I WAS ALSO TOLD THAT SINCE I HAVE LANE KEEP ASSIST THAT WILL KEEP MY VEHICLE FROM GOING OVER THE LINE. WELL I ALSO TRIED THAT AND THE CAR DOES SLIGHTLY PULL ME BACK IN BUT IF I PULL TO THE RIGHT OR LEFT ON OVER RIDE THE LKA WHERE IS MY WARNING. I CAN NOT BE THE ONLY ONE WHO NOTICED THIS. PLEASE HELP ME
