One problem related to coolant leaking has been reported for the 2018 Subaru Outback. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2018 Subaru Outback based on all problems reported for the 2018 Outback.
Since the car has been brand new, a half gallon of coolant has needed to be added to the car on a monthly basis. No leaks have been detected. There has always been a very strong odor of burning coolant. Dealer states this is normal for the 2. 5l engine, so there is nothing to repair, just keep an eye on the coolant level. I filed a complaint with Subaru of north America, and received a similar response. Both the dealer and Subaru state it is unknown how to repair this issue as they can not identify the problem causing the loss of coolant. Dealer just keeps topping off the system, and stating that they still have no solution.
