DRIVER SMELLED SMOKE SHORTLY AFTER STARTING HIS VEHICLE AND DRIVING AWAY FROM HIS HOME. THE SMELL WAS OF PLASTIC, AND IT WAS ASSUMED FROM AN ELECTRICAL SHORT/FIRE. THE DRIVER STOPPED THE CAR AND INSPECTED THE ENGINE AREA. NO EVIDENCE OF FIRE, HOWEVER THE DRIVER TURNED BACK AND DROVE THE VEHICLE HOME. STRONG BURNING PLASTIC SMELL AGAIN AS THE VEHICLE WAS STOPPED. THE CABIN WAS FILLING WITH SMOKE. DRIVER OPENED THE TRUNK AS THE BATTERY WAS LOCATED IN THE RIGHT REAR SECTION OF THE TRUNK. SMOKE WAS EMANATING FROM THE BATTERY COMPARTMENT. A PLASTIC PANEL WAS REMOVED FOR INSPECTION. LOCATED DIRECTLY UNDER THE BATTERY WAS A PLASTIC MODULE IDENTIFIED AS TRW *334 GNOACDOBNC28U* AND STAMPED MADE IN MALAYSIA??. THE DEALER STATED THAT THE MODULE CONTROLS THE ELECTRIC PARKING BRAKE FOR THE CAR. INSPECTING THE UNIT, MULTIPLE WIRE LEADS THAT FEED THE E-BRAKE CONTROL UNIT HAD BURNED THROUGH, AS DID A PORTION OF THE E-BRAKE CONTROL UNIT. THE BODY AREA OF THE CAR NEAR THE UNIT WAS COVERED IN SOOT FROM THE ELECTRICAL FIRE. YEARS PRIOR, THE DRIVER HAD ISSUES WITH THE E-BRAKE, THE E-BRAKES FAILING TO RELEASE PROMPTING THE VEHICLE TO BE TOWED TO THE DEALER. AT THAT TIME THE SERVICE REPRESENTATIVE WALKED THE DRIVER INTO THE SERVICE AREA TO SHOW THE DRIVER CORROSION ON THE ELECTRIC CONTACT LEADS FROM THE CONTROL UNIT. THE REPRESENTATIVE SUGGESTED THAT PERHAPS BATTERY ACID/GASES MAY HAVE RUN DOWN THE BATTERY INTO THE CONTROL UNIT CAUSING THE CORROSION. THE UNIT MAY HAVE BEEN REPLACED
