 I drove my Corolla for a year with the impression that it had a big-car feel and a very smooth feel (smoothest ever in fact).  Then something broke, and the dealership has been unable to fix it.  Now I do not feel safe driving on the interstate because if I hit even a small bump (and especially a series of small bumps) it feels like I am going to loose control.  At slower speeds, it is just uncomfortable to drive on anything but the smoothest of roads.  The dealership claimed to replace the front struts, and maybe they did because it did seem to reduce the rough feel for a 1-2 days.
