I was checking on the brake rotors on my 2017 Model X and took a look back behind the rotor and noticed that one of the suspension components, the spindle knuckle I think, is showing a surprising amount of corrosion. It's the same on both driver and passenger side. It looks crusty and shriveled. I've never seen anything like this before. My 2014 Model S, for comparison (the last photo with the red caliper), doesn't look anything like this.
Does this corrosion look normal to folks or like a problem? What do your spindle knuckles look like on your 5+ year old Model X? Should I be concerned about safety and potential failure on this component?
