Has anyone else had their rear hatch panel break (own 2018)
They break all the time. To replace them you take off the interior lift gate trim and can get to like 4 nuts that hold the part in. It's that whole chrome piece that comes off, with the stitch in it. I believe the nuts are 8mm and you'll need an extension and probably deep socket to reach them.
Check ebay or local junk yards for the part.
I own a 2018 Pathfinder and pieces simply fell apart in my hand as I was attempting to open the hatch.
