Exactly. Like Richie said, I have yet to hear of anyone reporting a major issue with sensor wire corrosion ... probably because if they suspected anything at all with the harness it's a 5 minute swap. I (like most Optima owners, I imagine) keep a spare harness in my kit for just such an issue; plus I believe it is one of the recommended parts to be replaced during annual service, regardless of any noticeable corrosion.
or they could just use the right connectors in the 1st place
all wiring and connectors in the head should be sealed - period.
this is a design fault - we shouldnt accept it.
but we do dont we. we make excuses, we happily carry spares and accept need for anual service replacement. Why?
