Hi all, my first post here, love what I've seen in the community so far. I read my issue on other posts here whereas there is a clicking sound at low speeds and its not constant. Found out it wasn't a rock or nail, but the axle needed to be lubricated. Tech said any rust build up will cause the clicking sound.... rust?? I've owned my Model S for less than 2 years. What also got me upset is that they are trying to charge me over $200 to lube the axle. Every post I've read here says they didn't pay a penny and its covered by warranty. So how do I push back if service center won't waive the fee? Thank you
