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.

Squeak/creak from center console. Turned out to be the black plastic gear shift surround rubbing on the console. Sprayed silicone lubricant under/around the black plastic gear shift surround. Squeak/creak eliminated. Doors would not latch in temperatures below 20 degrees F. Doors would open normally, however would not latch closed when trying to close the door. Sprayed silicone lubricant on the latch assemblies for the doors and trunk. Fixed issue. Loud knock/rattle inside dash when HVAC temp dial set in the middle of the cold/warm air setting. Sounds like the "blend door" rattles at this setting. Loudest on cold days. If problem persists when warmer will have checked by dealer. Hood was not properly aligned. Driver's side of hood was ~1/4" lower than passenger side. Raised the driver's side hood "bumper" and now hood gap is the same on both sides. Loud knock/rattle in vent system when temperature dial set at certain points. Dealer said the entire dash would need to come out to fix problem. Elected to live with it as opposed to having the dash removed. Front passenger seat vibrates while driving. Very loud metallic clunk and constant tick/rattle from seat back. Reclined the seat back a little farther, and raised headrest one notch. Rattle less frequent now, but not eliminated.
