NHTSA complaint #11760014

Owner complaint summary

Vehicle experienced significant drivability issues including shaking/clinking at speeds over 50 mph, check engine light, and reported two-cylinder misfires. Engine oil level was critically low, not registering on the dipstick, requiring approximately 2 quarts added to continue driving. An independent mechanic inspection found excessive oil in Cylinder 2 and assessed that oil was likely leaking past the piston rings and burning, recommending a bottom-end rebuild or engine replacement. Kia dealership (Sunset Kia) inspection subsequently found a score mark in Cylinder 6 and two external oil leaks (oil pan gasket and oil filter housing). Kia approved goodwill repair of the external leaks only, after which I was instructed to drive approximately 1,000 miles for a follow-up oil consumption test. After that period, the dealership confirmed the engine was still consuming oil beyond the external leaks. Kia Corporate took approximately three weeks to review a goodwill request for engine replacement, ultimately denying it. During this three-week period the vehicle remained at the dealership, and I incurred over a week of out-of-pocket rental car expenses due to no loaner vehicle being available and no transportation assistance offered. The vehicle has fewer than 100,000 miles. I am concerned this reflects an internal engine defect (oil consumption/piston ring or cylinder wall issue) affecting the vehicle’s safe operation, given the drivability symptoms (shaking, misfire, near-zero oil level) that initially prompted this investigation.
