NHTSA Complaint #11480444 — 2014 KIA SORENTO

We have 2014 Kia Sorento SLX V6 GDI with 110,000 miles. My daughter was driving and suddenly, the engine started to-make some noise and the Kia broke down and stopped in the middle of a busy highway. She was able to coast to the side of the road and the engined died. The engine starts but there is many clicking noises inside the engine. My mechanic says the engine failed and the car needs a new engine. I asked the Kia NJ dealer and they said the recall is only for the 4 cylinders, and that my car is not covered. The dealer said they'll fix it for $7,000. What a scam!! As I read all the complaints, our Kia V6 engine had that same issues everyone is complaining about. There are many complains with the V6 engine around 100k miles, not just the 4 cylinder. Why didnt the settlement include ALL engines that fail for the same reason, bad manufacturing. What can we do have Kia take this issue seriously? How can I force Kia to replace the bad engines? What can I do ??
