I have owned many Subaru's and really loved them all except for this problem. Catalytic converter is bad and estimated replacement is $2,000 to $3,000. I have spoken to some Subaru and non Subaru mechanics and all have said this is a common problem. I am not getting any satisfaction from Subaru USA and this has turned a loyal customer into a doubter. They tried a computer fix that did not work. They blame problem on hills and high speeds. The car also had bad rear bearing that were replaced as a recall.
