Everytime I see a thread on the RCM and bad solder joints, it always seems to mostly involve the '04, or '05 Model years. (Not a scientic survey, but just my observations).

Would this be because the issue was addressed by Chrysler on later model years, or might it be that the older the Model, the more chances that vibration , or ware and tear, might be a factor here...

(although any bad or cold solder joints had to come straight from the factory, or board maker)...

Inquiring minds would like to know...
