I have a new 2021 Limited with the manually adjustable passenger seat. The problem is the seat is very uncomfortable due to the seat seems to slope downward toward the front. If you are sitting in the passenger seat for an extended period of time it feels like you are going to slide off the front of the seat. I've looked and it doesn't seem to be adjustable up and down the way the electric driver's seat is. You can only move the seat manually front to back and adjust the back of the seat. Do any of you have passengers complaining about this issue? or is there something I am missing?
