There are 1 owner-reported fuel system complaints for the 2025 Kia Sportagein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Oil was being diluted by fuel seeping in from the injectors and the high pressure fuel pump. Vehicle was brought in twice to fix the problem. During the 24-27 Feb 26 repair the high pressure fuel pump was diagnosed and replaced. On 16 Mar 26 I noticed the oil level had risen on the dip stick (after driving ~300 miles) about 5 mm and brought the car back to the Kia dealer for diagnosis and repair. The high pressure fuel pump was diagnosed again as bad and replaced as were all four fuel injectors after they were also determined to be leaking fuel.
