I was curious why you're asking. Did the dealer you leased from tell you, or put in your lease terms, that you had to use them?
Just to CYA, if you have warranty work done at another dealer, be sure to be up front that it's a leased vehicle & make sure you're not on the hook for the bill.
Before you try to go to another dealer,check with both first. Because in the US there are franchise agreements between the distiributors and the dealers, some dealers get area rights to all KIA business. In other cases that does not happen and any dealer can do warranty work on any vehicle. I know this can be confusing but US manufacturers use distributorships that "own" an area whereas the foreign manufacturers do not always do this. Confused yet?

Shortly after buying a new 2008 Hyundai Santa Fe, the Las Vegas dealership went out of business, an effect of the recession starting.
Since I was commuting biweekly to SoCal, the Victorville dealership, ~200 miles from home, was happy to have my business. Don't recall being asked where I bought it.
The transmission was working fine, but it had a minor noise. That dealership stated that they were not permitted to work on transmissions, just exchange it.
I was very impressed with the work. Everything back together, as new.
Part of the reason I am continuing with Hyundai / Kia.
That's great - I'd rather have a new one than one that was worked on in a dealership. I've owned a lot of cars and I've never had an automatic that was rebuilt that was better than it was leaving the factory. Which is just another reason I prefer manuals.
