To STBRetired, I see your point. KIA could be saying we don't want to warranty vehicles with "invisible" miles so we will say the car is NOT towable anymore.
I have posed my question to Kia directly and I'm waiting for their answer. I saw that the Soul Base was listed by FMCA for 2019, so that's why we checked it out. None available, drove the 2020 and liked it, but afterwards I checked the owner's manual and found that flat towing was NOT recommended.
Thinking he had the sale all wrapped up (which might have been true) the salesman was not happy with what I found and lost the sale. Now, he's waiting for Monday to check with his "higher" authorities.
