18000 mi My 3rd attempt at repairing a stereo that comes on and off and changes the channel by itself. (replaced once) Driver power window switch & outer entry push button on handle both moody. Auto-delay headlights won't stay on at engine shut off. Driver power window switch inoperable at times. Window does not rise, usually when raining. Push button on driver's outer door handle for remote entry without using key does not work often. Pressing the button does nothing and no "click" is heard or felt and the door does not lock or unlock. A pain when arms full of luggage etc. I park in the dark often. The headlights are supposed to stay on for XX seconds after turning off the ignition for perimeter visibility. Rarely works, except for the dealer of course.
