I love my Model S, but she's one of the first built and has always been a bit temperamental. Last night on the way home the steering suddenly started making loud clicking and even screeching sounds when I turned the wheel. I don't know if this is serious or minor, but I wasn't comfortable driving the car; just imagine loss of steering control at highway speeds! So I returned to the office and arranged for a tow. I've been trying to get it in for a problem with the parking brakes failing to actuate, so at least both issues will be dealt with. (I've also got water in the reversing lights again, but they don't have the part in stock so next time.) Fortunately my Roadster was in storage at the office, and this was the perfect excuse to pull it out!
