There is no specific issue exclusive to the 2011 Jeep Grand Cherokee regarding oil leaks. Instead, common problems that affect all vehicles can also apply to this model. The main cause of an oil leak in this vehicle is typically degraded engine gaskets, accounting for around 95% of cases. When a seal wears out, becomes brittle with age, or is defective, it can fail and lead to oil escaping. In most cases, you can identify the problematic seal through a visual inspection. Besides gaskets, oil leaks can also occur from the oil pan itself, particularly the oil pan drain plug. If the plug has been over-tightened, it may strip the hole, resulting in a slow drip and the noticeable accumulation of oil under the engine.
