What does code 27 mean on the 2011 chevrolet cruze?

The code 27 on a 2011 Chevy Cruze means that there is an issue with one of Your blinks. This could be the result of one of Your bulbs going out or possibly because of a burned out fuse. The wiring being damaged is also a likely scenario. I would first try and replace the bulb and if that still doesn't work then try to replace the fuse. These are both issues where the items only cost a couple dollars each to replace and won't take too long. If You've changed those both out and there is still an issue You're going to need professional to check Your wiring.
