I've seen a lot of posts on here about cracked insulation on the wiring on Ex's. I've taken it to heart and inspected quite a bit of my wiring - and it looks good. I'm stumped because I've seen it enough to think it's an issue but my 11 year old vehicle doesn't seem to be affected. Does it only affect the V6 engines? That wouldn't make sense unless they use different wiring suppliers for the two engines. Anyone with a V8 have this issue? There has to be a common thread here on the wiring failures.
