Oil consumption on other Terrain years
No other Terrain model year has enough reports of oil consumption for a sheet of its own. See every Terrain year.
What this problem usually is
Two different complaints land here. The more common one is an engine that uses oil: owners add a quart between changes, get a low-oil warning, or are told by the dealer that the rate is normal. The other is the opposite, where the oil level climbs and the oil smells of gasoline. Both deserve a proper test, and both are easier to argue with records in hand.
What got replaced
Owners who name the part that was replaced mention the piston rings (5 reports).
