Check engine light came on again in my 2012 Terrain.
Onstar diagnosed as part of the emissions system not working as expected. I made a service appointment for this Saturday with the dealer. Anyone else had this issue?
Previous: 1999 Chevy Lumina Base
Current: 2012 GMC Terrain SLT2 AWD V6
20 mpg average
