In almost 2 years of ownership my coolant level has been significantly dropping for no apparent reason. Mechanics can't find the source of a leak. Topping off the coolant buys me a few months before the level dips again. This dip continues to happen until it reaches the neck of the hose. I have yet to risk letting it go below that. My engine oil has not showed any signs of coolant going into it. I have yet to see where this coolant is magically going.
