I thought I had read somewhere that they had fixed that issue but maybe not... I just installed a new one in my car a few months ago so I guess i will have to keep an eye on that!
Seems like there should be a solution.
You will likely be ok, as all the newer ones apparently have a yellow grease already applied.
Their fixes/solutions to issue is:
-drill 2-4 small holes about rotor height every 90 degrees in the side of the cap (newer caps have a vent/holes already)
-clean it all back up to new and coat metal parts, except pickup/wheel with dielectric grease
...and my dist may be older than 2 yrs, as this is when they rectified problem.
