I'm 6'5" just bought a 2019 Bolt LT. Read where a guy says his butt fell asleep in the car. The problem is caused by the thigh not been fully supported by the seat. I have a 2003 PT Cruiser which caused me the same problem. Easy fix: Remove the two front bolts holding down the seat tracks add washers to adjust the seat angle. I just needed about 3/4." Same discomfort in the Bolt. Same fix. The bolts are #50 Torx need to use a ratchet because they use Locktight on most bolts.
