What could they do for me at this point? It hasn't met lemon law status...yet and they paid $11k to fix it. I don't think my "feelings" matter to them at this point. I'd love for them to buy it back or give me a new one, but I don't see that happening.
sirruspilot, just don't give up. Hold their feet to the fire (respectfully, but consistently) and document the living heck out of everything that has gone wrong - you know the routine - how, what, when & where.
As others have already mentioned here, invite SOA to the party, and get them on board.
If the car continues to have problems, but you still haven't reached 'lemon law' status, you MAY be able to work out an acceptable solution with the dealer, SOA, or both. That is when your meticulous documentation can be valuable. Most people are too lazy to do this.
Be the voice of reason in anything that you work out - if the car is back together again, no noises, etc., well, you may not be able to do too much. But if it's a whining, groaning, just not right vehicle, maybe they can work out a pretty attractive deal on another one.
I've been where you are with a Toyota Camry, at one time (LOOOONNG AGO), the hallmark of Toyota quality. I was very close to invoking the newly passed 'Lemon Law' clause and had left my car at the dealership for one last chance to fix everything before I started filing paperwork. But, while it was in their care, despite my direct written orders never to leave the car out at night, they did just that, and a bunch of kids & an adult demolished it inside and out.
Solution: the owner of the dealership arranged for me to order a new Camry (new models hadn't yet hit the showrooms) for $500 under invoice, gave me a generous trade-in allowance on the remains of my previous Camry, and I drove a loaner until my new car came in six weeks later.
Hmmmm….got any kids around your Subie dealer?
Just kidding. Hang in there - you can work through this!
