Engine Noise problems of the 2012 Kia Motor Soul

In March 2019, vehicle began making noise and was brought in to kia dealership service department . Was told that oil was unexpectedly low despite last oil change in November 2018 and mileage/use of vehicle was much lower than normal during this time period. In October 2019, vehicle began making same noise and before it could be taken in, vehicle stopped functioning mid-traffic during left hand turn on to a side road from a 45 mph state highway. Brought again to same kia dealership service department. Technician reported on diagnosis report that "oil level seemed low (added 1 quart)" and verbally reported by phone that engine has unrepairable damage and entire engine needs to be replaced. We were quoted $6,000-$7,000 by the service department at the kia dealership to replace engine. Vehicle is currently sitting in our driveway unusable after being an extremely reliable vehicle requiring only regular and usual maintenance until March of this year.

Noticed that my car was making noise while driving. Checked oil and found there was no oil. I was getting oil changes at every 3000 miles then changed to 7500 miles per recommended. Changed back to every 3000 miles because of significant oil loss. Car was still burning oil and empty before 3000 mile change. Also noticed it was burning a significant amount of gas also. Took to dealership who did an induction test and told me I had carbon buildup on my pistons and my rings were sticking so I would need a new engine. Placed a claim with kia and they denied my claim siting poor fuel and lack of maintenance records. They said I was not using the "recommended" gas stations. I was not asked for any maintenance records and how do they know what gas stations I was using. I feel that this is a defect with the engine. I am currently at 85,000 miles.
