“STARTED SMELLING STRONG FUEL SMELLS SO TOOK VEHICLE TO DEALER. DEALER CALLED AND ASKED ME TO STOP BACK BECAUSE WHEN THEY DROPPED FUEL TANK THEY DISCOVERED FUEL LINES RUNNING FROM GAS TANK WERE SO BADLY CORRODED THROUGH THAT WERE SPRAYING PIN-STREAMS OF RAW GAS ALL OVER THE UNDERSIDE OF MY VEHICLE. SAID IT WAS A MIRACLE I DID NOT EXPLODE OR CATCH FIRE. MECHANIC THEN ASKED ME TO ALSO LOOK AT EVERY BRAKE LINE ON THE TRUCK WHICH WERE ALSO SO BADLY CORRODED AND DETERIORATING THAT HE SAID THEY WERE A REAL DANGER AS WELL AND ALL NEEDED TO BE REPLACED ASAP AT HUGE EXPENSE. MY VEHICLE HAS BEEN CAREFULLY MAINTAINED, ALWAYS CLEANED AND SERVICED AND SOUTHERN OHIO (WHERE I LIVE) IS NOT AN ESPECIALLY HOSTILE OR CORROSIVE ENVIRONMENT. I PURCHASED THIS TRUCK NEW AND IT HAS BEEN DRIVEN ALMOST EXCLUSIVELY IN THIS FAIRLY BENIGN ENVIRONMENT. THIS SEEMS SUSPICIOUS AND IS TOTALLY UNEXPECTED. *TR”
