I have had to bring my 2016 Enclave back to dealership to fix several issues that was missed on your 172 point certified vehicle. I still have an issue that needs addressing with front passenger side bumper. Clips must be missing. Original issues was passenger side parking light loose (fixed), moonroof screen broken (fixed) right passenger fender loose (fixed). Not sure how that was missed on original inspection (172). It was very hot the day we bought it and did not notice it ourselves until the next day while detail cleaning it ourselves. There was no dents so I believe that is why it was missed. Tom Gamewell did an excellent job helping us to find and have some work done already. I am going to the dealership Friday if open to talk with service manager about front bumper issue. If you would like to contact me they have my phone number.
