One problem related to radiator has been reported for the 2004 Subaru Forester. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Subaru Forester based on all problems reported for the 2004 Forester.
The engine overheated and seized while on a freeway without a single warning light regarding high temp or check engine. No coolant was visible in the radiator during inspection after the incident. Shouldn't a 21st century driver/owner be notified by some indicator that they are on the verge of heating an engine to the point of failure? and where did the coolant go? does this vehicle have a history of bad thermostats I'm not aware of? it would have been a lot safer if there were some warning light for high temp so we can pull over to allow the car to cool down in order to prevent an accident and save the engine.
