> diagnosis of moisture in fuel. Tech said he did not know why this was triggered and there was no way to test


LOL!


And how does one diagnose the problem as moisture in the fuel, if one cannot test the fuel for moisture?


They should hire some real mechanics at your dealership. It sound like the "moisture in the fuel" is the catch-all reason when they can't figure it out and just hope it goes away.


Sorry to be so harsh, but having seen mechanics do this to people many times in the past (when I worked as a mechanic), it ticks me off.
