Same here. Looks like 6'1" is the grey area where no matter how you position the seat back and headrest, the edge the rest rubs your scalp and makes you drop your head forward while you drive. I've had a few complaints from passengers too.At 6’1 & big melon head the headrest tilts my head down when back all the way. Leaning seat back helps some but not enough.
This all because of some law about headrest position. My 2011 Subaru Forester was the same as the JL. But my 2008 Nissan Frontier was just about perfect -- and every car before that too, including my old YJ, Cherokee and Liberty.
