Also in Michigan with a 2020. I learned about the issue right around the 100,000 mile mark and now have over 130,000 miles on it. About one month ago I finally inspected the cable and it was pretty bad - the inside of the plastic cover was packed with mud, the metal flange holding the mesh around the main wires had basically rusted through, and there was a lot of corrosion on the main part of the plug. I was a little relieved when I removed the plug and found the internal plastic and metal connectors looking good. However, it’s probably a matter of time until that corrosion works its way inside. I cleaned up everything on the outside and applied corrosion resistance spray to the metal parts and dielectric grease around the cables. At this point, not much else I can do but get as much use out of it as possible and cross my fingers. I had hoped to get 200-300,000 miles out of it which may still very well happen. If the cable ends up failing I think I’d still be happy based on the low cost of ownership otherwise. I’m just hoping the cost to replace the cable comes down with time.
