Took the 2010 CT in to check out why it was pulling to the left and as I suspected it was a wheel alignment. The Service Tech also let me know the rear axle where it goes into the differential was leaking and needed to be repaired. He also told me that it was covered under warranty and would need to order the part. I asked if this was common with the CT and he stated no just one of those things. Anyone else have this happen?
