We have noticed a great amount of oil consumption in the engine. We first thought we needed an oil change. We keep up on maintenance of our vehicles. When we took it in to get the oil changed, they said we had almost no oil in the vehicle. So once we had an oil change, we took it to Kia of Alcoa and they said there was nothing wrong with it. We drove it a while and again low on oil. We take it back to Kia of Alcoa and they do an oil consumption test. We drove it 1,000 miles like they said to do and we came back. They checked the oil level and they said the oil consumption was normal. So again we drive it and still having issues with oil consumption. We always have to put anywhere from 1 to 5 quarts of oil in the vehicle on a regular basis. We should not have to add oil in between oil changes. Now we have a rattling going on and we are taking it back to Kia Alcoa soon to get looked at. We believe that rattling is from the high oil consumption. Nobody seems to have a solution and everyone thinks there is nothing wrong with the vehicle.
