My story is very similar to many of you. Check engine light came on last Monday. Took it to dealership, they thought Wednesday. Got a call Friday part was back ordered and never showed up. Today they say because the car is so new parts are difficult to locate. Keep it as long as you need it until it's fixed. I bought the car in November 2012, the SEL,2013 version. However taking it to a different dealership than where I purchased it from. Original dealership service dept is disorganized, (been there once already and was without car for 2 days due to the SYNC system). Where the C-Max is now...service dept is top shelf.
