We had a 2015 Sorento with a similar issue. Kia said the oil burn rate was within specs and refused to act. It died at 105k, and they refused to do anything about it, even with documentation of the oil burn rate going back to 75k miles. We replaced the engine on our own dime, and it took me three weeks to find a single engine that was compatible.
That said, a few months ago my daughter was t-boned in it by a driving going 60+ MPH. The impact was directly on the driver’s door. She not only survived, but did so with only superficial facial cuts and some longer-term, back pain.
I can’t be too hard on a car that saved my daughter’s life.
