What Owners Say
""Electrical issues-Fuse box corrosion, Wiring harness had to be replaced, faulty ECM module.""
Anonymous A., PA (2012 GMC Acadia SLT 3.6-L V6)""overheats easily, sensor issues. literally afraid it will stall if it overheats in summer traffic or when stuck in commuter traffic, after first time we experienced that, after we purchased it. then, found out that was common with acadias. which is great, in a state that gets up there in temps and traffic jams, and you are stuck.""
Anonymous, AZ (2012 GMC Acadia SL 3.6-L V6)"The exhaust system Y-pipe with the flex joint failed at the flex joint causing an exhaust system noise as well as a failure code to show in the exhaust emission system. I had to replace the exhaust y-pipe assembly to fix the problems this failure caused."
