2014 Hyundai Elantra sport w/ 6spd manual clutch replacement at 70k

I have a 2014 hyundai Elantra spt 6M
So I got my engine replaced under warranty about 6 months ago @65k miles, since then problems have been happening, a loose seal leading to oil burning, strut
tower bolts left loose, and now at 70k miles, 5k after the engine replacement, they are saying my clutch needs to be replaced at $1860.
It started the day I picked my car up from being serviced, and having the strut tower bolts tightened, I immediately noticed that getting the car into and out of gear was much more difficult. I drove the car for about a week before I was able to take it back and as the week progressed the shifting got more difficult, and it even started to grind.
I have been driving stick for 15+ years, and a majority of the miles on my car were freeway miles. So I find it very difficult to believe I wore the clutch out. I put 200k on my last clutch.
I've already called the Hyundai help line, and I have put a call into the service manager of the dealership.
What else can/should I do?
