Struggling to find the right SUV

Looking to buy a new luxury SUV for longer car rides (2.5+ hrs) that offers a quiet comfortable ride, that also fits 3-4 6’+ tall people. 2nd row legroom 40”+ is critical. Was strongly considering MB GLE450 but very discouraged about ongoing maintenance issues…also considering Lexus TX550+, Lincoln Corsair, Hyundai Palisade, any insight is appreciated.
