hard downshifting coming to stops
The "thumping" of the transmission coming to stops got worse. Took her to the dealership again. The dealership was very diligent in working to resolve this. They had the Terrain for 2 days, did some tear-down, couldn't find any visual issues, so then drove 3 Terrains of the same year and powertrain. They involved their transmission guy, service tech and foreman. They all reported that all of these Terrains have this problem! I elevated this to GMC customer service, they looked into it for 2 days, and called me back. The answer I received floored me - I was told that there was nothing I could be offered for a resolution since this seems to be "characteristic of the vehicle" and the "vehicle is performing as designed." Amazing... So a poor design is something customers apparently just have to live with. If the Terrain had done this when we test drove it, we would not have purchased it. It's a real shame, because it's a great vehicle with a lot of great features. But, when design engineers squeeze a few bucks tossing the same transmission in this SUV that is in the Chevy Cruze, this is what happens. I would advise readers to go with the 3.6L with the heavy transmission (6T75), but I have 2 friends who have experienced far worse problems with this powertrain in an Acadia and Traverse. I guess GMC's quality focus is simply not there even after all these lawsuits and recalls.
