Even positioned all the way back, the headrest is still too far forward for my neck. Anyway have the same issue and found a replacement? Hopefully the hole spacing is standard, as I'm going to try various acquaintances' Headrests. Lol.
Looks like some folks with regular Souls have the same complaint. It stems from newer active Headrests requiring a certain angle to prevent whiplash. Some have gone so far as to reverse their headrest and straighten the two metal bars.
