My baby threw a rod. I noticed the oil was low so I added oil. Went to work and on the way the engine started knocking. My Kia dealer has it and today thank God they said they will replace the engine. I wasn't sure if they would because I hadn't changed the oil in a while (about 7,000 miles). I also don't have good records of all my oil changes, but I did have some receipts in the glove box. From now on I will use the Carfax app and record everything and make sure maintenance intervals are followed to a tee. I thought I was going to lose my car.
