2019 cx5. 32k miles. Noticed a few drops of oil in my garage. Got down on the floor with a flashlight and the bottom of the car is covered with oil. Brought it in for oil change and inspection. They said there was oil all the way back to my exhaust. Tech told me back of engine was covered in oil. Dropped the car off with them today. They gave me a loner. Just got the call that it was a cracked cylinder head. Warranty covers it 100%. They say work will be completed by early next week. Went online, found this thread. Thought I should share.
