I purchased this car with 12,000-15000 miles still relatively new (v6). Every time its time to get my oil change, there is 0 oil left. My car burns all the oil before the next oil change every time. I consistently got my oil changed on time, my most recent oil change was yesterday at 58k miles. Before its even time to get my oil changed I'm forced to buy an extra quart of oil because its bone dry empty. There is also a knocking sound. The last person to change my oil told me they had another GMC Terrain they were working on with a siezed engine from the same problem.
