Yo Ghetto, do you have the bike or is it still at dealer?
An examination, simple as wiping your hand down along thew fork tube below the seal will tell you if you have a leak, there wil be tell-tale oil there.
Could be simple single occurance blow by or blown seal. If seal then it depends on your feeling about your ability to do the work with what tools you have. If you have to buy tools to perform the work then it maybe cheaper to let the dealer have this one.
While not required it would be nice to have a lift ($80) basic metric tools ($? depends on you already have) seals and oil ($50-$70) special tools (seal install tool could be made from PVC pipe cheaply $10, seal removal hook $10, snap ring plier $10)
The work isn't difficult but you can see that if you're not well equiped it could get over $200 easy to do yourself. You be the judge here.
I'd personally like to make a close inspection. I don't have the USD forks like you but I reared a woman in a car at a sign a couple years back, not that hard 5-10 mph, and it bent the tubes at the trees. With your forks I'd be worried about bending at the seal interface. That could create sticking action during compression and rebound.
Be careful during refill not to over fill. Air is compressible, oil is not. If over full at full compression it will bottm as hard as if it was solid and then there's no where for the oil to go except passed the seals.
