I took my 2011 to the local dealer for it's last oil change (4 years in service in a week or so). Drove it home that afternoon and parked in the garage, as usual. Friday morning I pop the hood and pull the dipstick to check it. No, I just had an oil/filter change it's not possible that the oil looks dirty and is 5.5 inches up the stick. Check again, smell the oil. Appears the the dealer was kind enough to make me wait nearly 2 hours for my service but didn't bother to change the oil (and filter) I'm guessing, just ad some oil. I then carefully drove the 6 miles back and let them see for themselves although I probably should not have driven the car. This was a disaster waiting to happen had I not checked. ALWAYS check after having this service done, even at your "trusted" Cadillac dealers service department.
