MY AIRCONDITIONER FAN SWITCH HAS NOW GONE ONCE AGAIN AND IS IN NEED OF "ANOTHER NEW ONE, THIS WILL BE 3. THE PAINT ON MY HOOD IS STARTING TO CRACK A BIT AND WILL BE PEELING SHORTLY. THIS CAR WAS VERY WELL MAINTAINED AND GARAGED AND THERE WAS NO REASON FOR THIS! THE POWER WINDOWS WENT ABOUT 3 DIFERANT TIMES ON BOTH SIDES OF THE VEHICLE AND THE SWITCHES HAD TO BE FULLY REPLACED. THE RADIO HAS A SHORT IN IT IN THE BACK SOMEWHERE AND THE DISPLAY GOES CRAZY AT TIMES. LASTLY AND MOST IMPORTANTLY, I HAVE HAD A WATER LEAK ON THIS CAR SINCE 1999. IT HAS BEEN INTO THE DEALERSHIP TOO MANY TIMES TO COUNT. THEY CHANGED OUT THE WINDSHIELD AT LEAST 5 MAYBE MORE TIMES, CHECKED ALL THE SEALS ON THE SIDE MIRRORS AND THE SUNROOF, CLEANED OUT THE DRAINS ON THE SUNROOF A FEW TIMES AND AFTER THE CAR WAS IN THE LAST TIME 8 MONTHS AGO, THEY TOLD ME THAT IT WAS THE LAST TIME THEY WOULD DO ANYTHING ABOUT IT. IT WAS FIND W/NO WATER UNTIL LAST WEEK WHEN WE HAD POURING RAIN AND IN FLOODED MY INTERIOR ONCE AGAIN. PONTIAC'S SOLUTION WAS TO GIVE ME $1,000 FOR THE PURCHASE OF ANOTHER CAR, THANKS FOR NOTHING! IN DOING MY RESEARCH I HAVE FOUND OUT A LOT OF INFO THAT I AM ONCE AGAIN GOING TO PONTIAC/GM ABOUT. ON MY PARTICULAR CAR WHEN THEY MADE THE DRAINS FOR THE SUNROOF, THEY MADE THEM TOO SMALL, SO WHEN IT POURS OUT, THE DRAINS CANNOT HANDLE ALL OF THE WATER AND IT IS FORCED INTO MY CAR. I WORK FOR AN INSURANCE COMPANY AND HAVE SPOKEN TO "MANY, MANY" PEOPLE REGARDING MY CAR. FUNNY THING IS, I HAVE HEARD THIS FROM SEVERAL GLASS COMPANIES AND DEALERSHIP SALESMEN! WHAT CAN BE DONE ABOUT THIS TO HELP ME, THE CONSUMER? ANY HELP IS WELCOME

The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
Consequence & remedy
Consequence: Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Remedy: The remedy applied under recalls 08V-118, 09V-116, and 15V-201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engines front valve cover and gasket. Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number.

ON JANUARY 29, 2007, THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED A PRELIMINARY EVALUATION TO INVESTIGATE ALLEGED NON-CRASH FIRES ORIGINATING IN THE ENGINE COMPARTMENT IN CERTAIN MODEL YEAR (MY) 1999-2002 PONTIAC GRAND PRIX GTP VEHICLES EQUIPPED WITH THE ?L67? SUPERCHARGED VERSION OF THE GENERAL MOTORS (GM) 3800 SERIES II V6 ENGINE.TO DATE, ODI IS AWARE OF 121 NON-DUPLICATIVE COMPLAINTS ON THE SUBJECT VEHICLES THAT ALLEGE NON-CRASH RELATED FIRES ORIGINATING IN THE ENGINE COMPARTMENT WHILE DRIVING OR AFTER THE VEHICLE IS PARKED AND THE IGNITION SWITCHED OFF. WHILE NO SUBJECT COMPONENT HAS YET BEEN IDENTIFIED, ODI ANALYSIS OF AVAILABLE INFORMATION INDICATES THAT THE ALLEGED FIRE INCIDENT RATE AMONG THE SUBJECT VEHICLES IS SIGNIFICANTLY HIGHER THAN GM PEER VEHICLES THAT USE THE NON-SUPERCHARGED ?L36? VERSION OF THE GM 3800 SERIES II V6 ENGINE.IN SOME CASES, THE FIRE INCIDENT RATE IS TWICE AS HIGH IN THE SUBJECT VEHICLES AND UP TO AS MUCH AS AN ORDER OF MAGNITUDE GREATER THAN IN NON-SUPERCHARGED PEER VEHICLES.FOR INSTANCE, THE SUBJECT FIRE INCIDENT RATE FOR THE SUPERCHARGED MY 2000 PONTIAC GRAND PRIX GTP IS APPROXIMATELY 236 PER 100,000 VEHICLES PRODUCED (58 FIRES / 24,509 SUBJECT VEHICLES OR 0.236%) WHILE THE FIRE INCIDENT RATE FOR MY 2000 PONTIAC GRAND PRIX VEHICLES EQUIPPED WITH THE NATURALLY ASPIRATED ?L36? ENGINE IS APPROXIMATELY 18 PER 100,000 VEHICLES PRODUCED (17 FIRES / 90,338 VEHICLES OR 0.018%). THE MANUFACTURER?S INVESTIGATION INTO ALLEGED ENGINE COMPARTMENT FIRES ON THE SUBJECT VEHICLES IS ONGOING.ACCORDINGLY, THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA07-008) TO FURTHER STUDY THE FREQUENCY AND SCOPE OF THE ALLEGED DEFECT.
