So it turns out the reason the first run-in service was late was because there were no stock of front differential fluids in all service centers in Korea.

Many others were affected by this and got a late service.
Warranty is fully alive.

Also, I took the car out for test drive (for 2 days) and car is very normal and strong.

Even at 6500mile since the last engine oil change, the oil level is still at full.

I'll post more update after I acquire the car.

Thanks for your concerns.
