Since the first year of ownership, I have noticed that the vehicle burns oil excessively. I reported this issue to the kia dealership, but I was told that “it is normal to add a quart of oil every other week. ” despite this statement, I believe this is not normal and points to a defective engine design consistent with the piston ring problems known in similar models and engines. In the summer of 2025, the vehicle began having hard-start issues when the engine is hot. Over time, I replaced several components at my own expense through an independent repair shop, including the alternator, starter, pcv valve, map sensor, and camshaft sensor. None of these repairs resolved the problem. When I returned to the dealership, they performed a borescope inspection and found scoring and damage on three cylinder walls inside the engine block. Thats whats causing the engine to seize when the engine is hot and make it hard to start and misfire when accelarate.
