Oil change should be fairly simple and fast. If I go down the street to a fast change oil place, I'm done in 15 minutes. There was a problem I found out later with another car . No one came to tell me that my car would take longer . No one told me where my car was after it was finished. I asked 2 people and it still took me 5 minutes to find it. I love my jeep, but I don't love your service department. If I don't tell you that you have a problem, then you can't fix it!!
