NHTSA Complaint #11031457 — 2008 JEEP COMPASS 4X4

EVERY TIME I FILL MY CAR WITH GAS I EXPECT THE CAR TO STALL AND TURN OFF WHILE I'M DRIVING DOWN THE ROAD. IT'S EXTREMELY DANGEROUS AND IT HAPPENS EVERY TIME. THIS IS A KNOWN ISSUE WHICH JEEP NEEDS TO ISSUE A RECALL FOR AND REFUSES TO. IT IS EXTREMELY DANGEROUS TO HAVE PEOPLE DRIVING ON THE ROAD WHOSE ENGINES CAN SHUT OFF AT ANY MOMENT CAUSING THEM TO COME TO A COMPLETE STANDSTILL EVEN IN THE MIDDLE OF THE HIGHWAY. THE PROBLEM IS THE VAPOR/LIQUID SEPARATOR VALVE LOCATED AT THE TOP OF THE FUEL TANK. THE VALVE IS DESIGNED TO PREVENT LIQUID FUEL FROM ENTERING THE CHARCOAL CANISTER/EMISSIONS SYSTEM. WHEN THE VALVE FAILS, LIQUID GAS CAN ENTER THE LINE AND FILL THE CHARCOAL CANISTER. AFTER REFUELING THE PCM ON THE VEHICLE DETECTS A CHANGE IN FUEL LEVEL. THEN, WHEN THE ENGINE MEETS CERTAIN TEMPERATURE AND DRIVING CRITERIA, THE PCM ISSUES A PURGE COMMAND TO THE CHARCOAL CANISTER TO REMOVE THE STORED GAS VAPORS. IT'S AT THAT POINT THAT ALL THE LIQUID GAS IN THE LINE GETS SUCKED INTO THE CHARCOAL CANISTER. THE PCM EXPECTS TO SEE GAS VAPORS ENTERING THE INTAKE MANIFOLD AND IT IS PREPARED TO ADJUST AIR/FUEL MIXTURES TO COMPENSATE. HOWEVER, IT IS NOT PREPARED TO SEE LIQUID GAS COMING INTO THE INTAKE. THAT'S WHAT CAUSES THE ENGINE TO STALL. UNFORTUNATELY, THE ONLY FIX IS TO REPLACE THE ENTIRE GAS TANK.
