NHTSA Complaint #11652700 — 2015 KIA SORENTO

Kia Sorento Limited 2015. Regular oil changes on engine using Valvoline synthetic oil. 118k miles on the 3.3L engine. Car is in mint condition. I have all records. At oil change, Valvoline tech mentioned it was low on oil. Never had a tech tell me that before. 24 hours after oil change, I started the engine and heard a pinging noise. I let the engine warm up and the sounds smoothed out. I drove it for less than 5 minutes on the highway at 60mph and warning lights came on and the car had no power from the engine. No loud sounds or knocking at the time. Kia South Dealer is telling me I have to buy a rebuilt engine for $5.5k and will cost $6K to install. That cost is more than the car is worth. With me research, there are two huge issues with the engine. Head bolts loosing and lack of oil distribution on one cylinder causing bearings to melt. I know there is not a recall on this but there is on the same engine for the Hyndai Sante Fe. I baby this car and I feel very betrayed that the engine gave it the way it did. My car looks brand new as I take great care of it but now I have an engine that should last twice as long that is now dead. Shouldn't this engine should be applicable for an extended warranty or for Kia to step up and help with the cost? What can I do? Really appreciate your help!!!!! Sincerely, [XXX] Original Owner since I bought it Dec 2014. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
