2018 Cadillac Escalade

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 locked in the bottom and metal with metal makes sounds on bumps and bricks streets. When purchased I used to take vehicle to dealer but actually it continues with issues and I just lost confidence and pricing and turnaround were not convenient. Unfortunately, the 2018 Escalade is the worst vehicle decision I have made in my life. When told service manager that I couldn’t believe how a 2018 vehicle was failing engine and again, he told me he has seen 2024 so it shouldn’t be surprising. More to say but will keep simple
