+fireamx I had no intention of sounding condescending. I did appreciate your suggestion of a traction control malfunction as it had not occured to me before.

I included my "resume" lest some forumite would think that my only aquaintance with the mechanical aspects of my car consisted of handing the keys to the dealership's service manager.

To clarify the comment about the car changing shape; in summer the top of the side windows was about 5mm below the bottom of the drip rail, when the temperature dropped to 10ºF the top of the side windows was about 3mm above the bottom of the drip rail. That meant that closing the door left the top of the window pressing on the outside of the drip rail with the rear of the window held away from the seal by the width of the drip rail.

Thanks for the manual page onehundred80. It seems to indicate that the rear body shell from the top of the windshield back on the top and from the rear of the doors back on the sides is adhesively bonded to the rest of the car.

Yes, the car has been hit from behind while stopped in August of 2006. I first complained about the darting and window and door problems in October of 2004.

Each of the six times I took the car to the selling dealership for these problems they told me they had checked the alignment. The tires are worn evenly with no cupping or feathering on the edges.

Thanks to everybody who suggested taking it to a frame shop for measurement. That is now on my to do list.
