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

The radio in the car keeps dropping sxm signal while driving down the street or highway or entering parking lots at nearby supermarkets or our lowes store. I have written Cadillac and am waiting for their response. While not a safety issue per SE, it is frustrating and not expected on a car that cost almost $64,000.

Cadillac XT5 2017 luxury fwd model vibrates at all speeds. Accelerator and steering wheel vibrates. Tires have been balanced and rotated with no improvement to the constant vibration. Water sloshes out of bottle in cup holder, jacket falls off clothes hook in backseat, eggs break in egg carton all due to significant and constant vibration at all speeds.

Defective upper dashboard has large ballooned area in center where adhesive either failed or wasn't applied and lower dashboard has defective lump under material. These defects should never have left the factory. Poor quality control. Both dashboards are to be replaced by dealer.
