We recently brought our Chevy Cruze in due to a check engine light. On the way there, the radio display went out, so we asked them to check that too. The diagnosis for the CEL was a failing particulate sensor that would need replacement (~$450+) and the diagnosis for the display was a failed display that would need replacement (~$600+). We declined the repairs and went home, to decide what to do. While checking to see if we could at least get the fan to blow, we started looking at fuses and found a blown fuse for the display. Replaced fuse, display now works. So.....did they not even check the fuses???? Also, while searching about the particulate sensor I came across a policy memo that extends the warranty for the particulate sensor for 10 years/120K miles, so they should replace it for nothing. Do they not search for warranty info? I found it fairly quickly once I knew what was wrong. Next time I get a CEL, I will just get the code taken at Autozone and look up the code myself. I don't trust them anymore.
