Two problems related to coolant leaking have been reported for the 2011 Subaru Outback. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2011 Subaru Outback based on all problems reported for the 2011 Outback.
Due to a well-known design flaw the engine had a severe head gasket leak. The leak lead to a foaming of the coolant and a pressure break in the coolant reservoir. The car had a catastrophic failure on the freeway and could have lead to a serious accident. The car was serviced the previous August by a dealer. They have refused to answer my direct question if they did a flushing of the system which could have led to the damage but, it is a well-known problem that the Subaru 4 cylinder 2. 5 l engine has had a severe flaw in its design.
Coolant is leaking onto top of engine block in two places. It looks to be leaking where the coolant crossover pipe connects to the engine both sides.
