I started to hear a rattling sound from under neath the car 2014 outback 2.5i. Took it to Subaru dealer he said its the resonator. He also said it was not covered because even though its making a horrible rattle sound its not broken and they don't repair for noises under warranty. I said if the resonator never made that sound the first three years then its broken. He said the resonator is still doing the job its designed for so its really not broken, its just making a noise from something inside the resonator. hmmmm So I'm asking how many of you have heard of this and am I getting hoodwinked with having to pay $395 to replace the whole assembly. Would love some help on this one.thanks
