“I have a pretty bad oil leak. Mechanic said it's a failed head gasket. He did tell me that my car is too new with a lower than average mileage for it to have failed the way it did. He actually told me to complain to you guys and also fight with the dealership and Subaru of north america because I should not be having this problem. He said it's all on them.”
