KIA Motors review: 2016 kia sorento engine

in March 2023, engine light came on giving us codes. In April 2023, we took the car to Hendrick Kia in North Carolina and discovered that the following: HEAVY ENGINE

REPLACE INTAKE CAM, ALL 4 CVVT'S, TWO TIMING CHAINS, TWO TIMING TENSIONERS 4,507.96

AND INSPECT FOR ANY ADDITIONAL DAMAGE ON REMOVAL

All items replaced and vehicle seemed to be better. On 9/29/23, went to pick up rental for out of state trip and my car started knocking badly, went from nothing to real bad on the 15 minute trip from rental place to our home. had towed to dealership on 10/18 after returning from trip (felt unsafe to drive it) we got the results back from Kia dealership and they stated rocker arm bent and engine now needed to be replaced and issue was caused due to running vehicle on low oil for long periods of time (which never happened; had oil changed about every six months). also note, that this happened so quickly that no code ever appeared on car beforehand and we also have it in writing that dealership did not see a code as well when they did the inspection. was referred to call Kia customer care to open a case and see if they would do a good faith engine replaced and was just advised today that they have declined but won't give me any reason beyond it was declined to be done. note: our car doesn't even have 80k miles on it
