Don't just assume that the problems your are having are directly related to the TSB's. Sometimes new/different problems are found that can be similar to those you are having. i can also assure you that the techs at your dealer have all of the info ( including all of the updates that we have yet to get our filthy little hands on) about your car. If you want to let the dealer know exactly what the problem is, ask to go on a test drive with the technician. People do it all the time at the dealership i work at. Best of all you can show the tech the exact problem. As for the squeeky belt, you may have to leave your car there for the day. Maybe even over night so they can start it first thing in the morning when there's enough moisture in the air to get that belt to squeel. Good luck. Remember this. Be nice to the service writer and techs. Just like anyone else in the world, if you DEMAND something from them, you are less likely to get what you need.
