There is no prepayment penalty. I also took the $1000 finance rebate and financed the least possible amount ($6k) that the dealer will agree on to get the rebate. Dealer said that $6k is the minimum that Kia will agree to finance. I paid off the loan when my first payment was due even though the car salesman told me to wait for 3 months to pay off. No penalty.
When I bought my Soul at Kia of Cerritos (sucks) I easily qualified for Kia Financing at 2.9% plus $1,000 rebate. When I got the the finance manager, he drew the contract up for
5.9%! I told him that was not our agreement. He re-wrote the contract for
3.9% ...again not what we agreed on! He said the additional 1.0% is for "dealer participation"...whatever THAT is. That 1.0% goes
straight in the stealership's pocket! Long story short, I paid off the loan before the first payment was due with a credit union loan of 1.95%.
I think the dealer only gets his "dealer participation if the loan lasts longer than 3 months. I would love verification on this though!
But to answer your question, the problem was with the dealer, not Kia Motors Financing. No pre-payment penalty on my part. I just hope the dealer gets screwed out of the additional 1.0%. They screwed themselves.
