NHTSA Complaint #11595709 — 2017 KIA FORTE

The vehicle consumes excessive oil, requiring to top-off oil every ~1k miles to prevent engine damage and seizing. The owner of the vehicle first observed oil consumption at 90k miles oil change. Dealership performed oil consumption test, measured 0.5qt oil burned in 1k miles. At 95k mile oil change, owner requested to record oil consumption, but dealership did not measure it. At 99k miles, owner again requested to record oil consumption, and dealership measured 1.5qt oil burned in 3k miles (0.5qt / 1k miles). After 99k miles, owner began topping off oil every time the oil was measured to be 1qt low. Measured adding 1qt every ~2k miles. Oil change performed at 105k miles with no additional notes. At 108k miles, dealership began second oil consumption test, and measured 1.5qt oil burned in 1k miles (3x increase in oil consumption from 99k miles to 109k miles). Dealership recommending "Hail Mary" attempt to break up carbon build up in cylinders or recommending engine replacement. Manufacturer and Dealership claim that even though the problem began while under warranty, it only became "bad enough" after warranty ended, so the owner must cover all costs himself.
