Yes! I have the at4 with same package. I have 10k miles. The last few months, i cant go longer than 20 min with pain starting in my low back. It only happens when i drive the truck. The seats are hard as rocks. Even my wife commented on how uncomfortable the passenger seat was the first time she sat in it. She has a 2018 acadia with leather. Every time i drive the acadia, i notice immediately how soft and comfortable the seat is. For a 67k truck, this is unacceptable. I hope gm can recall. / resolve.
