Getting off-topic but the same as jeebusm3, after I read about the freezing sliding doors latches recall I started a yearly treatment of lithium grease instead of taking it to the dealer and haven't had the problem. (dunno) QUOTE]
A few weeks ago I experiences the freezing door lock syndrome but only on one door. My wife took it to the dealer and it worked ( defrosted). As soon as I got home from work, I pumped all the door locks with Royal Purple Synthetic lube.
On a similar topic, my mechanic friend told me to take lithium grease and wipe it all along the door seals ( rubber) before the winter to ensure the door seals never freeze against the car during those really frigid nights. Worked like a charm this winter with all the rain, freezing rain and snow coming down within 24 hours (alright)(alright)
