I had heard the thump in the steering but didn't give it a lot of attention until Homer pointed out that steering problems are nothing to fool around with. So Friday a.m. I tried to get the service department on the phone. When I couldn't I drove in with no appointment -- I was all set to argue my way in, but they took the car with no problem. The message on my answering machine said, "just a little adjustment to some bolts on the steering rack." So thanks Homer for making me take the thump seriously, and thanks to this forum for making me aware of the many issues with the MO. Fortunately the thump is the only issue my MO has had so far.
