This strange chirping noise is back on my 2012 V6. I purchased this car back in Dec '12 and last winter this noise appeared. I live in LA and during the hott summer this noise did not appear at all. As soon as it got cold (50-60 degrees F) at night the sound appears. It's on the drivers side and i can't seem to pinpoint the sound. Anybody got a clue to what it could be? My last resort would be spraying DW40 in every place imaginable just to get this annoying sound out!!!
