NHTSA Complaint #11419760 — 2012 KIA SORENTO

Hello,My engine began to make a knocking noise and high rev when started approx. 2 weeks from today. I took it to a local mechanic, Archers automotive, Whittier, Ca., and he advised that I needed a new engine. The mechanic advised me of numerous recalls on the 2012 Kia Sorento engine and recommended I take it to the dealer. I made an appointment with Kia Cerritos and about a week later I took it to Kia in Cerritos, Ca. on 06/02/21. On 6/4/21 I was advised by Service advisor "Ryan" i needed a new engine, I advised Ryan that I am the original owner who purchased this vehicle new and I advised him there are numerous recalls and safety issues with the 2012 Sorento but I was advised my engine for some reason is not recalled. I advised him It is obvious Kia has an engine issue with their 2012 Sorento based on the recalls and the numerous complaints on the web.There were no warning lights of an engine issue. The moment I noticed an issue with how the engine was sounding I took it to a mechanic and then to Kia Cerritos. It had been inspected by Kia Cerritos by a mechanic and on a diagnostic machine. When I initially asked for the reason why the engine needed replacing, On 6/4/21, I was advised the mechanic did not list any reasons. When I asked for the service codes I was advised the mechanic misplaced the diagnostic print out and he had to put it on the machine again, which leads me to believe they initially did not test it on the machine. I was told by Ryan at 10am I would get a call back that day, no call. On 6/5/21 Ryan at Kia Cerritos advised me the engine needs replacing and the cost would be $10,000, but they could not say why because the bearing test used on 4cyl recall engines would not work for 6cyl engines but he advised the "sound" it makes is similiar to the recall engines. My vehicle is available, anytime, within a reasonable distance from zip code 90604,  for inspection from NHTSA and anyone from Kia.I look forward to hearing from you. I have included all ppw
