general problems of the 2013 Cadillac XTS

Automatic headlamp leveling system malfunction causing safety issues with nighttime driving.

Vehicle radio and dashboard is completely blackout, started flashing and later went black in a month time.

I purchased this vehicle October 20th 2017 and within 2 weeks the service driver assistance system light came on. Took it to dealer was told was old code and erased a few days later same message came on was told dash was cleared and gm case filed. A few days later light came on for 3rd time. Dealer toyed us around about fixing it but finally supposedly did with new sensors in seat. Since then I have been having major electrical issues with my abs system and key fob. Key fob becomes unresponsive and abs light comes on and off. Took car to dealership was told abs sensor was supposedly broke and not covered under warrentee and they refused to fix the issue for me. I am very affraid to drive the vehicle it sits parked in my yard and I paid over 20k for it. I feel I have been taken advantage of because I have a disability with my speech. I have documentation about key fob and abs I can send if needed. The car was driving when the abs light came on went off and traction control came on then off then back on. The key fob wouldnt work when trying to turn car off because it has push button the fob controlls starting it and turning it off.
