Consumer Description

No FireNo Injuries0 Deaths0 I’m experiencing severe oil consumption and spark plug fouling, which are known problems with the GDI engine. This is affecting driveability and may indicate piston ring or valve seal failure. My engine code starts with G4KJ which falls under the current recall, but my vin does not show up. Why isn't my car eligible? I have called Kia and their response was to call my local dealership. Started noticing the issue on [XXX]. Called dealership at that time and they said my car doesn't qualify. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
