Great styling, amazing features but definitely not up to high-end luxury when it comes to fit and finish. This 2018 premium luxury awd has more rattles and shakes than a baby rattle. After further research I found that my rattles are not a one offs, but a common set of issues across the 3 year run The worst of which is a lift-gate design that was more fitting of a 2010 Chevy Blazer than a high end luxury vehicle with no sound dampening at all, a plastic cover panel that is so poorly designed it rattles even after many feet of dealer installed two way tape under it. Next a split rear seat that shakes and rattles over every bump unless you leave the whole center section down ,leaving the two halves separate to shake on there own but making less noise. I have also had to have all 4 doors taken apart to fix interior rattles caused by what I was told is water shields lose inside and they said rear doors Loose speaker attachments. All of which still rattle after fix so need to go back There is also a clicking sound metal in tone that comes from the front dash that is yet to be diagnosed. Having owned this new vehicle for 6 weeks and having it in my possession less than half of that. I can say the fit and finish team at GM needs a overhaul.
