2009 Subaru Legacy 80,000 mi,
My car started to vibrate during acceleration in 3rd gear only while I was still under warranty. I brought my vehicle to the dealer and they could not figure out what the issue was. Now at 96,000 and no longer under warranty, this issue persist and is now occurring in 1st gear as well. All help on this issue is much appreciated.

Loud rattling. Mechanic said I needed to replace my catalytic converter, but called Subaru and it's part of the recall, so it's free.

considering purchasing this vehicle. not sure how long the previous owner operated the vehicle with this problem. the only thing I noticed is the shutter on shifting 1st to 2nd gear. I have an automatic.
