I've been experiencing the same thing. I took a long trip a few weeks ago and spent the first night in so much pain that I couldn't sleep. I came to my 2017 Terrain from a sedan so I think this set up will take some getting used to. My nurse friend theorized that it is because I'm sitting more upright than in the sedan.
To resolve I lowered the seat as far as it would go, moved it back until I could just reach the pedals safely and made sure there was very little tilt so it didn't hit my leg behind my knee. I made subtle adjustments from there until I was comfortable. Doesn't completely solve the problem but definitely helped. Good luck.
