The seats are beyond uncomfortable/hard and are not supportive. Long trips (2.5 - 3 hours) are a nightmare and cause me back pain.

Within a month of driving the 2018 Honda Fit, I began experiencing severe left hip pain due to the un-supportive seats especially for your thighs. It's so bad I am seriously considering trading it in at a loss. I would like Honda to replace the seats with a better engineered one that is conducive to a human being sitting in it without writhing pain. If that doesn't work, then foot the bill for an after market replacement seat.
