NHTSA Complaint #10573673 — 2008 PONTIAC GRAND PRIX

THE ENGINE COOLANT SYSTEM CLOGGED UP MY THERMOSTAT AND COOLANT TURNED TO A BROWN CONSISTENCY AND THICKENED LIKE MUD. MECHANIC STATED THAT THE COOLANT, DREX, CAN HAVE NO FLUIDS ADDED, AND NO WATER UNLESS IT IS DISTILLED. I DID NOT ADD ANY COOLANT OR WATER AND RECEIVED NO COOLANT LOW WARNING. I PREVIOUSLY HAD CAR WORKED ON ONE YEAR AGO FOR THE SAME PROBLEM. I WANT ALL VEHICLES EVERYWHERE WITH DREX FOR COOLANT RECALLED AND REPAIRED. DREX IN THE COOLING SYSTEM IS A DESIGN FLAW. I THINK EVENTUALLY IN A COOLANT SYSTEM SOME MOISTURE FORMS FROM THE HEATING UP AND COOLING DOWN PROCESS OF A RADIATOR AND CONDENSATION FORMS. THIS WOULD THEN GUM UP AND RUIN A CARS COOLING SYSTEM AND COULD CAUSE THE VEHICLE TO OVERHEAT AND POSSIBLE THE ENGINE TO BE RUINED. THIS IS THE SECOND CAR WHERE I HAD TO DO REPAIRS BECAUSE THE DREX CLOGGED UP THE RADIATOR AND MADE MY ENGINE OVERHEAT. *TR
