Our 2017 Cruze with 3400 miles is smudging black liquid out the exhaust tip. I cleaned chrome tip once but it is back a week later. At some point I will take the car back to the dealer and ask them but this is my first new car since 1990 and I do all my own maintenance. I am new to this forum and was wonder how many do it yourselfer are lurking on this site. Has anyone seen this before?
