Hey guys, I tried searching the threads but couldn't find anything on this. I was wondering if anyone can help identify a sound that started happening a few weeks ago. It's not a sound listed on Tesla's website. I hear it near the front bumper and it almost sounds like a servo motor opening or closing something. It only happens after parking and keeps going for a several minutes. I'm not sure if it's due to the cold weather now but I'd just like to know if it's something to be concerned about. Thanks!
