The dealership states that this is not a big problem and that the headlights will not be affected but the malfunction light stays on and the exclamation point is on the dashboard. The fix: $717 to replace the rear sensor harness where corrosion on the connection and pin was found - new harness assembly needed. Any suggestions about just replacing the pin? Dealer states you cannot cut the wire and replace becaue the wires are not sealed.

**_I’m Not Sure What Is Meant By “the connection and pin,” But On Many Manufacturers’ Vehicles The Pins In Connectors Can Be Replaced._**

I’d go from the dealer to an “Auto Electric Shop” that specializes in car starter / charging and lighting systems in cars. See if there’s a good one in your locale.
