2018 CADILLAC ESCALADE Unknown Or Other Problems

It been twice that I have experienced lifters issues and damage caused to engine because of these. First time I fixed it in a NY mechanic shop because dealer workflow and expecting dates (all lifters, crankshaft, and seals were replaced new), less than 1 year later again the lifters failed (2) but this time ruined my engine. Went to local GM dealership and asked at service department if they could fix it complementary due to all reported lifters issues from GM as we all can see online and rejected my offer. So far vehicle is still not fixed and it’s been 5 months in shop looking ways to see if engine could be solved but have to replaced. Also on the Escalade 2018 the seats (middle seat row and 3rd are really being noisy, I purchased vehicle 3 years ago with about 80K miles but these seats are not fully...

WHILE DRIVING THE 2018 ESCALADE ESV RWD ON INTERSTATE 87 NORTH YESTERDAY, DRIVING ABOUT 33MPH, THE ESCALADE SUDDENLY SWERVED LEFT AND SLID INTO THE MEDIAN AND THEN ROLLED OVER ON ITS ROOF. AFTER THE ACCIDENT, I NOTED I HAD RECEIVED DIAGNOSTIC ONSTAR EMAILS THAT MORNING WHILE DRIVING THAT THE VEHICLE STABILITRAK AND ANTILOCK BRAKE SYSTEM WERE EXPERIENCING ISSUES. I ALSO PHONED ONSTAR TODAY ABOUT IF AND WHEN THEY RECEIVED A CRASH NOTIFICATION. THE CRASH NOTIFICATION DID NOT OCCUR WITH ONSTAR UNTIL THE VEHICLE WAS TURNED BACK OVER, NOT WHEN THE CRASH OCCURRED BUT AN HOUR LATER. THE VEHICLE IS LESS THAN 60 DAYS NEW.
