In cold weather I notice a lot of noise, too, but it's to be expected. It's plastic and it will expand and contract and squeak and sound like it's cracking. I don't have leak issues so I don't worry about it anymore.
Sounds like you're on a "pay no mind" list, lol. Not a problem up here in NEPA yet, unless they are busy on their phones, then they don't see you wave.
