This vehicle is burning oil at an alarming rate. Between oil changes it has lost 4 quarts before. I constantly have to check and add oil and have experienced stuck pistons and rough idle due to the oil not being at a safe level. Kia service advisors have admitted there have been reports of this happening with this engine, but no recall or inspection has been initiated to my knowledge. They did just issue an optional emission campaign that I completed, but it is unrelated to the oil burn issue.

Also case number from Kia [[redacted]]. As there is no current Recall Kia refused to take responsibility. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
