As a follow up to my original post: Say hello to my (not so) little friend! I learned a few minor things: A/C still makes weird noises (gurgling) but only if it's really hot The Window seals squeak way louder in the heat As of yesterday, sometimes I hear a loud "click" in the back of the car whenever I go over a bump, enter my driveway, or the car seems to "flex" on a rough road. This sound is comparable to the "click" of the rear liftgate locking into place. I'm hoping it's not anything major and just the new car settling, but I'm worried if it's my rear motor or axle? That being said — I really love this car in ways I could have never imagined, and I'm only posting this to start a discussion to help someone who may have these same quibbles. It sucks that my service appointment is in 1.5 weeks and I can't really tint my car until the window thing is fixed. I will try WD40 Silicone in a couple days and report back with the results.
