NHTSA Complaint #11418554 — 2012 KIA SORENTO

2012 Kia Sorento, approx. 135,000 miles, driven by my daughter who is away at college. Vehicle is rapidly losing oil, but it is not leaking/dripping or smoking. At a recent regularly scheduled oil change (which was done sooner than recommended) the mechanic advised that no oil drained out. Over the next several days and 550 miles later, my daughter needed to add two quarts of oil just to get the dipstick level to "low". I have read numerous complaints from Sorento owners with the same issue, who have been told they need a new engine. Our vehicle is no longer under warranty, but that may be a moot point as I have also read that Kia is somehow not repairing the ones that are still under the original manufacturer warranty. I am concerned about the safety of my daughter driving a car that may experience sudden engine failure. For now, she is adding oil every week until we can get the car diagnosed.
