Occasionally smelled anti-freeze after careful inspection could not determine where leak was. Had to add anti-freeze on two occasions. Took car to gm dealership for oil change and was told of the problem. He showed me the leak and advised I should get it repaired ASAP. Estimated repair cost at this point is in excess of $1,000. It was also advised that if not repaired this could result in antifreeze in the oil which would ruin the motor. This problem is related to the gasket they used, which is plastic and has since been changed.
