Subaru Outback brake squeaking issue and head gasket problem with oil mixing in radiator reservoir on Subaru Outback

Some Subaru Outback owners report experiencing brake squeaking issues, which can arise from worn brake pads, lack of lubrication on brake components, or brake dust buildup. These problems often necessitate a professional inspection of the brake system, and regular maintenance can help prevent such issues. Additionally, some Subaru Outback owners report serious head gasket problems that lead to oil mixing with coolant in the radiator reservoir. Symptoms of this issue include bluish-white exhaust smoke and poor idling, indicating a blown head gasket that requires immediate attention to avoid further damage. The Subaru EJ251, EJ252, and EJ253 engines are particularly vulnerable to these head gasket problems due to their composite-style head gaskets. Prompt resolution of head gasket issues is crucial to prevent costly complications and potential engine failure.
