2008 BUICK LUCERNE Fuelpropulsion System Problems

Fuse box (rear) 2008 Buick Lucerne CXL. FUEL PUMP Relay burns fuses out quickly. The fuse box located under the back seat has been having issues of burning where the fuel pump relay is located. It then in turn shorts out the fuse box which keeps needing to be replaced. This is a safety issue as it catches fire under the back seat. Fuse box has been replaced before and continues to have issues and melts, causing the vehicle to die in mid traffic, does at stop lights or even just parked and running it dies out and smells like burning plastic. The fuse box has caught fire several times. The issue has been confirmed by several mechanics and dealerships. Also there is a history of electrical problems with the rear fuse box in carfax. There was no warning, and now the check engine light is illuminated. We bought the...

Our Buick Lucerne would crank but wouldn't turn over when trying to start after trying to pick up take out. 1) It was suggested to me by a passerby that it sounds like a fuel pump relay. 2)I started to smell something burning. The passerby who happens to be familiar with Buick Lucerne tried to help. He lifted the back seat and showed me the fuel pump relay which was burned. Then he switched the electrick window relay which is the exact same relay switch and the car started. Went immediately to an autozone and bought spare fuel pump relay. Thought that solve the problem, but every 2 to 3 days I'd smell that burning smell. 3) The mechanic I've been going to for 10 years confirmed the issue 4)Have not taken to dealer or insurance rep 5)Absolutely no visual warning on dashboard. the warning happens when I start smelling...

Bought my car Sept. 2022.Within the first couple of months I started having intermittent problems that seemed fuel related.After some research I found out my car had a TSB that has been out since 2016. With this knowledge I took the back seat out of my car and the problems all stopped.June of 2023 started having some problems that were sort of similar to what I was experiencing before with some power loss, had vehicle taken to mechanic who diagnosed an interlock system problem.I thought maybe that would fix all my problems and put my back seat back. I travel 4 hours once a month to go see my son and only took my car once on that trip because of not being able to have a back seat.Me thinking the interlock fix was the solve all to my problems I put the back seat in and started my drive...

I went to start the vehicle and it failed to start. I found the fuel pump relay to be badly burned 🔥. On the 30 pin. The board was melted at the 30 pin spot for the fuel pump relay. I purchased a new relay from NAPA. I questioned whether they had a new replacement fuel pump. They told me it was not available only through the dealership. My concern was that where the relay was located at there was a possibility of a fire given how badly the relay and board was burned. I replaced the relay and purchased an extra incase this might happen again. To my surprise it happen just days later while I was driving on the expressway. I had to get off the road immediately. Engine died, no power steering. I checked the relay, it was smoking hot. I will have to have the problem...

The rear fuse box burned out the fule pump relay because of the metal hooks for the seat hit it and pop the fuse out causing it to ark and burn out. I had to have the fule pump replaced twice as that what I was told at auto shops. Going on line was the only reason I found out about the fuse box. After my car died and wouldnt start, opened the casing and sure enough the fule pump housing was completely burned. So now after replacing two fule pumps my emergency money is gone and who knows how long it will before am able to buy a 400$ fuse box with probably another couple hundred in labor to change it out. All because there was to much metal on the seat hooks.

The fuel pump relay keeps getting hot and burning, causing the car to not start or loosing power while driving. Lost power going up a hill and around curve with no place to pull over. Could have been hit when car died in blind spot in road. Looked it up and other people on line are saying it is the seat clips hitting fuse box causing short circuit in fuse box and damaging fuse box. People said they thought it was fuel pump but still had same problem after replacing fuel pump. A lot of upset people on line saying there should have already been recall on this problem. Have had 2 mechanics look at it. Have bought 3 relays. Afraid to drive car if it will start, fear of loosing power in middle of road and getting killed. Not to mention could cause fire since fuse box and battery...

1. Fuse box was replaced, yes. 4th repair shop replaced. I say only time will tell for sure. i don't drive every day 2. driving I-95 from VA to MD at speeds of 30+ to 75+ cars driving close behind could have ran into rear causing my car, their car, and multiple other cars to be in major accident with possible multiple deaths. 3. reproduced, no. independent service center, no 4. No. Other - the 4th repair shop inspected vehicle component. 5. No warning lamps. No messages or symptoms, car just stalled and would not start/move and w​hen I tried to start car again car would not start, but had all kinds of warnings lamps lit up. The first time the engine stalled was driving (moving) into entrance of toll booth in Richmond, VA, July 27, 2021 approx. 2:15 pm. additional info: Four (4) times car stalled while driving in...

-The electrical system failed, causing the fuel pump to not work properly due to design flaw in the backseat putting pressure on the fuse box which is located under the backseat. The spot where contact is made to the fuse box, is where the fuel pump relay is. Pressure from the seat bracket (with or without a passenger in the seat) causes the pump replay to not make proper contact with the terminal, therefore causing the power to arc and get so hot that the relay starts smoking, melting the relay, fuse box and surrounding fuses and leaving black scorch marks on the inside of the lid to fuse box and making the car smell like burnt plastic. In addition to now having to purchase multiple replacement relays it has also caused additional electrical issues which resulted in having to replace multiple fuses as well as purchase another battery due...

WHEN I FIRST BOUGHT THE CAR OVER A YEAR AGO THERE WERE 3 DIFFERENT OCCASIONS THAT MY CAR WOULD NOT START SO I CONTACTED THE DEALERSHIP THAT I BOUGHT IT FROM AND THEY EXPLAINED TO ME THAT IT WAS A REOCCURRING PROBLEM WITH THAT MODEL FOR THE FUEL PUMP RELAY TO GO OUT AND AFTER A COUPLE TIMES OF IT GOING OUT IT WOULD ULTIMATELY FRY THE FUSE AND RELAY BLOCK AND IT WOULD NEED TO BE REPLACED SO THAT IS WHAT THEY DID AT THE DEALERSHIP AND WITHIN THEY YEAR THAT I HAVE OWNED IT I HAVE REPLACED THE FUEL PUMP RELAY 3 TIMES AND DRIVING TO THE PARTS STORE LAST WEEK THE CAR JUST DIED IN THE MIDDLE OF THE STREET AND HAS NOT STARTED SINCE. I WAS TOLD IT WAS DUE TO THE HINGE ON THE SEAT RUBBING THE SIDE OF THE FUSE AND RELAY BOX SPECIFICALLY...

RECENTLY REPLACED FUEL PUMP. AFTER REPAIR, CAR WAS STILL A CRANK/NO START. REPLACED FUEL PUMP RELAY WHICH HAD OBVIOUS BURN/SCORCHING EVIDENCE, AS WELL AS MELTING AROUND FEMALE PORT ON THE FUSE BOX. SINCE THEN HAVE HAD TO REPLACE 3 OTHER NEW FUEL PUMP RELAYS DUE TO PROBLEM OF EXCESSIVE HEAT OR ELECTRICAL SURGE FRYING THE RELAY. AFTER RESEARCHING THE PROBLEM, IT WAS FOUND THAT THE PROBLEM IS CAUSED BY THE BACK SEAT OF THE VEHICLED COMING IN CONTACT WITH THE TOP OF THE FUSE BOX CAUSING THE RELAY TO MOVE, CAUSING THE RELAY TO WORK HARDER TO MAINTAIN A CONNECTION, WHICH IN TURN CREATES MORE CURRENT AND THE RESULTING HEAT INCREASE MELTS THE CASING IN THE FUSE BOX AND KILLS THE RELAY. WHEN THE RELAY IS COMPROMISED IN SUCH A WAY THE FUEL PUMP STOPS OPERATING AND THE ENGINE GETS NO GAS THUS CREATING A CRANK/NO START IF THE CAR...

FUSE BOX UNDER THE SEAT OVERHEATS AND BURNS OUT FUEL PUMP RELAY ALONG WITH THE FUSE BOX. UNSAFE IF IT HAPPENS WHILE DRIVING

EXPERIENCED A CRANK NO START ON MY 2008 BUICK LUCERNE, DID SOME RESEARCH TO FIND THIS MAKE/MODEL/YEAR HAS A LONG HISTORY OF ISSUES WITH THE REAR ELECTRICAL CENTER DUE TO THE PLACEMENT UNDER THE BACK SEAT. THE FUEL PUMP RELAY FUSE WAS EXTREMELY BURNT AND NOTICED THE FUSE BOX WAS MELTED NEAR THE RELAY FUSE. BROUGHT MY CAR TO THE LOCAL BUICK DEALERSHIP AND THEY NOTIFIED ME A 10 YEAR "SPECIAL COVERAGE" WAS AVAILABLE ON THIS CAR BUT I WAS NEVER NOTIFIED OF THE ISSUE. I AM THE 2ND OWNER OF THIS VEHICLE. ENDED UP HAVING TO PAY FOR AN ENTIRE NEW REAR ELECTRICAL CENTER AND THE LABOR TO REPLACE IT (~$700). I CALLED GM CUSTOMER SERVICE AND THEY SAID THEY WOULDN'T BE ABLE TO DO ANYTHING ABOUT IT. IF THE ELECTRICAL BOX IS BEING BURNED AND IT'S DIRECTLY UNDER A SEAT I FEAR THIS IS A MAJOR SAFETY CONCERN....

CAR WOULDN'T START CHECKED FUSE PANEL AND FUEL PUMP RELAY TERMINAL IS MELTED UPON FURTHER RESEARCH THIS IS A COMMON OCCURRENCE IN THE 2008-2011 BUICK LUCERNE MODELS CAUSED BY THE PANEL BEING DIRECTLY UNDER THE REAR SEAT BRACKET. BRACKET APPLIES PRESSURE TO PANEL LID WHICH INTERN PUSHES AND APPLIES PRESSURE TO FUEL PUMP RELAY GM RECOMMENDS REPLACING RELAY WITH LOW PROFILE STYLE RELAY AND CUTTING SEAT BRACKETS. IF THIS IS SUCH A KNOW ISSUE AND GM RECOMMENDS THESE MODIFICATIONS WHY IS THIS NOT A SAFETY RECALL? IF THE TERMINAL IS MELTING AND BURNING LIKE THAT THIS COULD CAUSE A FIRE DIRECTLY UNDER A FOAM SEAT IN THE REAR OF A CAR AND IN MY CASE DIRECTLY UNDER MY CHILDREN'S CAR SEATS!!!!!!!!! I HAVE TO REPLACE THE ENTIRE FUSE PANEL DUE TO THE MELTED CONTACTS WITH ESTIMATE REPAIR COSTS OF OVER $300 FOR SOMETHING THAT COULD BE PREVENTED BY GM DOING...

THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 135,000.

"TAKATA RECALL"RELAY TO FUEL PUMP IN FUSE BOX UNDER DRIVERS SIDE REAR SEAT. KEEPS MELTING (RELAY AND FUSE BOX) LEAVING AN ELECTRICAL FIRE SMELL IN CAR. THIS IS THE 2ND BOX AND FUEL PUMP TO BE REPLACEED IN LESS THAN 2 YEARS.

CRANK NO START. BACK SEAT HOUSING WAS PUSHING AGAINST FUSE BOX IN BACKSEAT CHUSHION CAUSING FUEL RELAY TO NOT WORK. RELAY WAS DAMAGED AS A RESULT. FUEL PUMP WAS ALSO DAMAGE

THE CAR SHUT DOWN AND WILL TURN OVER BUT WON'T START AGAIN THE RELAY FOR THE FUEL PUMP IS MELTED AND THERE IS NO VOLTAGE GOING TO THE FUEL PUMP FUSE IN THE FUEL BOX UNDER THE BACK SEAT OF THE VEHICLE THIS SHOULD BE A RECALL DUE TO A FIRE COULD START OR THE VEHICLE COULD SHUT DOWN AT ANY MOMENT AND CAUSING A ACCIDENT AND OR DEATH

TL* THE CONTACT OWNS A 2008 BUICK LUCERNE. THE CONTACT STATED THAT THE VEHICLE FAILED TO START WITHOUT WARNING. THE VEHICLE WAS NOT TAKEN TO AN INDEPENDENT MECHANIC OR DEALER FOR DIAGNOSTIC TESTING OR REPAIRS.

WAS DRIVING AND VEHICLE STARTED TO STUTTER,HESITATE , THEN TOTAL LOSS OF STEERING BRAKES DIDN'T WORK PROPERLY. WE WERE ON AN OVER PASS DURING RUSH HOUR TRAFFIC BUSY INTERSECTION. FINALLY AFTER ABOUT 1 HR WE MADE IT TO AUTOZONE LIMP MODE ALL THE WAY. PURCHASED COILS X 3 , COIL IGNITION MODULE, SPARK PLUG WIRES,SPARK PLUGS, CAMSHAFT SENSOR,CRANKSHAFT SENSOR. THEN FIND OUT IT WAS ONLY A FREAKING FUSE UNDER SEAT THAT WAS BURNT AND MELTING AWAY. NOT VERY HAPPY. GM SHOULD BE HELD ACCOUNTABLE FOR KNOWING ABOUT THIS AND NOT OFFERING TO FIX IT.

FUEL PUMP RELAY BURNT UP IT IS UNDER BACK SEAT REPAIR SHOP SAID THE CAR WOULD HAVE BURNT UP COMPLETELY IF CONTINUED MY LITTLE BABIES RIDE IN BACK SEAT AS REQUIRED BY LAW I WOULD NOT GET THEM OUT IN TIME IF THE CAR ON FIRE UNDER THEM1 HELP HELP

MY BUICK HAS BEEN CONSTANTLY BREAKING DOWN AND EVERY MECHANIC HAS TOLD ME THE SAME PROBLEM. IT IS THE FUEL PUMP AND THE FUSE BOX UNDER THE SEAT. I NEVER THOUGHT THAT I WOULD HAVE ANY PROBLEMS SINCE BUYING THIS CAR IN 2016. BUT, I HAVE HAD NUMEROUS PROBLEMS AND ALL I SEE ARE RECALLS ON MY BUICK. EVERYTIME I CALL IN TO COMPLAIN AND ASK ABOUT THE RECALL ITS ALWAYS SOMETHING NEW AND THAT YOU GUYS CAN'T DO ANYTHING. THIS WAS MY FIRST PURCHASE FOR MY 21ST BIRTHDAY AND I NEVER WANT A BUICK EVER AGAIN. IF THERE IS SOMEONE THAT COULD HELP ME REGARDING MY FUEL PUMP AND FUSE BOX PLEASE CONTACT ME AND MAYBE YOU COULD DO BETTER AND SEND ME THE PARTS TO FIX MY CAR. THIS IS RIDICULOUS AND I HOPE SOMEONE COULD CONTACT ME RIGHT AWAY.

GAS ,PUMP AND RELAY STOPPED WORKING . REPLACED PUMP THREE TIMES, PUMP RELAY ONCE. CAR WILL NOT START AGAIN. ANOTHER PUMP . NUMBER 4.CALLED GM CHECKED ON RECALL NOTHING .THIS ALL WITHIN A TWO YEAR PERIOD.

THE CAR WAS PARKED AND WOULD NOT START HAD IT TOWED TO A REPAIR SHOP. THE REPAIR SHOP FOUND THE FUEL RELAY HAD OVER HEATED AND MELTED THE FUSE PANEL UNDER THE BACK SEAT. I DID SOME RESEARCH ONLINE AND FOUND ON REPAIR PAL THAT 105 OTHER PEOPLE HAD THE SAME PROBLEMS. EBAY SELLER HAS SOLD 1264 FUSE BOXES LIKE THIS ANOTHER EBAY SELLER SOLD 275 FUSE BLOCKS FOR BUICK AND GM CARS. DID SOME MORE RESEARCH FOUND PROBLEMS BACK TO 1996 2006-2011 BUICK LUCERNE'S HAD ISSUES.

FUEL PUMP RELAY BURNED OUT TWICE. SCORCH MARKS FROM SERIOUS OVERHEAT POSSIBLY FIRE ON BOTTOM OF REAR SEAT. CAR STOPS IN MIDDLE OF ROAD WHEN FUEL PUMP RELAY APPEARS TO POP LOOSE SHUTTING OFF FUEL TO ENGINE. HAVE TO PRESS AND WIGGLE RELAY TO RESTART CAR. POSSIBLE BAD CONNECTION IN FUSE BOX UNDER REAR SEAT.. RECOMMEND MAKING MANUFACTURERS BE PROHIBITED FROM INSTALLING BATTERIES AND ELECTRICAL FUSE BOX FROM INSIDE PASSENGER COMPARTMENT. HIGH FIRE HAZARD IN CASE OF ACCIDENT!!!

LOST POWER WHILE DRIVING 65 MPH ON HIGHWAY WHICH CAUSED POWER STEERING AND BRAKES TO BECOME HARD TO USE. I TOOK IT TO MECHANIC AND FOUND THAT THE FUEL PUMP RELAY HAD OVER HEATED CAUSING THE FUEL PUMP TO STOP. I LOOKED ON RECALLS ON THE INTERNET AND SAW WHERE THIS HAS BECOME A COMMON PROBLEM WITH THESE CARS AND THAT GENERAL MOTORS REFUSES TO ISSUE A RECALL. THIS IS A VERY DANERVOUS CONDITION AND NEEDS TO BE CORRECTED.

I BOUGHT THIS BUICK USED A COUPLE OF MONTH AGO WITH 87K. I'VE SINCE DRIVEN OVER 4K MILES. I BOUGHT THIS CAR BECAUSE IT WAS A BIG TOURING CAR AND I NEEDED SOMETHING RELIABLE AND COMFORTABLE FOR LONGS DAYS ON THE ROAD. SEVERAL HUNDRED MILES AGO IT JUST WOULDN'T START IN THE DRIVEWAY. RESEARCH LED ME TO THE FUSE BOARD. CHECKED THE FUSES AND RELAYS FOUND NOTHING OBVIOUS. CAR STARTED UP A FEW MINUTES LATER. THIS HAPPENED LATER THAT DAY WHEN IN ANOTHER CITY AND THEN A FEW MORE TIMES THAT DAY. ALMOST HAD IT TOWED BUT THEN IT STARTED. NOW, AFTER ALMOST 1000 MILES IT GAVE UP THE GHOST AND I FOUND ONE OF THE TEETH ON THE RELAY BURNED AND THE PLASTIC PARTIALLY MELTED ON THE RELAY HOUSING AND THE FUSE PANEL. WENT TO THE PARTS STORE AND BOUGHT A RELAY REPLACEMENT BUT IT DIDN'T DO ANY GOOD....

TL* THE CONTACT OWNS A 2008 BUICK LUCERNE. THE CONTACT STATED THAT THE VEHICLE WAS LEAKING FUEL FROM UNDERNEATH THE FUEL TANK AND ABOVE THE EXHAUST SYSTEM. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

WHEN READY TO LEAVE WORK THE VEHICLE WOULD NOT START. DETERMINED THE FUEL PUMP WAS NOT OPERATING. REPLACED THE FUEL PUMP AND THE VEHICLE STILL WOULD NOT START. I FOUND THE FUEL PUMP RELAY WAS THE ULTIMATE CAUSE OF FAILURE. AFTER REPLACING THIS RELAY TWO OTHER TIMES I DECIDED TO LOOK FURTHER INTO THE CAUSE. I DISMANTLED THE FUSE BOX TO FIND IT WAS NOT COMPLETE INSIDE. THE FUSE BOX IS FILLED WITH FEMALE TO FEMALE COUPLERS TO CONNECT THE BOTTOM WIRING HARNESS TO THE FUSES. THE FUEL PUMP RELAY SHOULD HAVE FOUR OF THE COUPLERS INSTALLED IN THE FUSE BOX. THERE ARE ONLY THREE INSTALLED. THE MALE PINS ARE LONG ENOUGH TO TOUCH AND MAKE CONTACT. THEY WILL EVENTUALLY OVERHEAT. THIS IS A MANUFACTURING DEFECT AND A FIRE HAZARD; AS MANY PEOPLE HAVE HAD THE ISSUE. BUICK STILL HAS NOT ISSUED A SAFETY RECALL AND REFUSES TO ACTUALLY INVESTIGATE...

TL* THE CONTACT OWNS A 2008 BUICK LUCERNE. THE CONTACT STATED THAT THE VEHICLE FAILED TO START.

FUEL RELAY BURNT SO REPLACED FUEL PUMP AND RELAY AND MY BRAND NEW RELAY JUST BURNT UP WHILE SITTING IN DRIVEWAY MY WIFE WAS DRIVING THE CAR WHEN CAR STOPPED AS SHE WAS LEAVING THE PARKING LOT OF A FRIENDS HOME WHERE I CHANGED THE FUEL PUMP AND FOUND OUT RELAY WAS BURNT AND NOW IT'S MELTING RELAYS

FUEL PUMP SHORTS OUT AND MELTS THE FUSE BOX THIS WAS WITH THE CAR PARKED IN THE DRIVEWAY COULD BE A FIRE HAZARD IF THIS HAPPENS YOU LOSE ALL CONTROL OF THE CAR AND MAKES IT A DEATH TRAP

WE WERE OUT OF TOWN WHEN CAR FAILED TO START, NOT BATTERY RELATED. HAD TO BE TOWED TO SERVICE CENTER WHERE THEY DIAGNOSED, INSPECTED, AND REPLACED THE FUEL PUMP RELAY. ON 10/01/2015, 2000 MILES LATER SIMILAR INCIDENT EXCEPT THIS TIME MY LOCAL MECHANIC. HE CLEANED ALL CAVITIES, APPLIED DIELECTRIC GREASE, CHECKED THE FUEL PUMP AMPERAGE AT 7.5, TIGHTENED ALL RELAY CONTACTS AND REPLACED RELAY. BAD RELAY HAD SCORCH MARKS AROUND SEVERAL PINS. ON 10/07, 500 MILES LATER, SAME SCENARIO EXCEPT THIS TIME REPLACED FUEL PUMP MODULE. ON 10/10, AGAIN NO START, SIMILAR, SYMPTOMS. MECHANIC CAME TO MY HOUSE ON 10/12, COULD GET CAR TO START AFTER SEVERAL TRIES, TESTING AND MANIPULATION OF COMPONENTS , BUT IMMEDIATELY SHUT IT DOWN SINCE RELAY WAS VERY HOT. CONCERNED OVER SAFETY, HAD TO REPLACE THE WHOLE MODULE. REPLACEMENT MODULE WAS DEFINITELY AN UPGRADE TO ORIGINAL AND WAS SUCH BECAUSE OF, I UNDERSTAND, THE FAILURES...

HAVING A PROBLEM WITH THE CAR NOT STARTING. IT WAS STATIONARY IN THE GARAGE. HAD IT TOW TO GARAGE. THEY DIAGNOSED IT WAS A FUEL RELAY BURNING UP. A NEW RELAY DID START THE CAR.WE TOOK A SHORT TRIP OUT OF TOWN AND THE CAR STOPPED RUNNING...LEFT US STRANDED ON THE HIGHWAY. THE RELAY GAVE OUT AGAIN. A MECHANIC WILL NOW LOOK INTO THE FUEL PUMP REPLACEMENT. AND ELECTRICAL BOX UNDER THE SEAT.

THE FUEL PUMP RELAY OVERHEATED AND MELTED IN THE FUSE BOX. I HAD TO HAVE THE RELAY AND FUSE BOX REPLACED. THE MECHANIC TOLD ME THAT THE FUSE BOX COULD HAVE STARTED A FIRE. HE TOLD ME TO GOOGLE THE PROBLEM WITH MY CAR BECAUSE HUNDREDS OF OTHER CAR OWNERS HAVE HAD THE SAME PROBLEM. SURE ENOUGH I DID JUST THAT AND I SAW HUNDREDS OF PEOPLE WITH THE SAME COMPLAINT ABOUT THIS MODEL CAR. GM NEEDS TO BE HELD ACCOUNTABLE. ARE THEY WAITING UNTIL SOMEBODY DIES FIRST BEFORE THEY ACKNOWLEDGE THE PROBLEM OF THE FUEL PUMP RELAY AND THE FUSE BOX? BTW I HAD TO REPLACE THE FUEL PUMP.

TL* THE CONTACT OWNS A 2008 BUICK LUCERNE. THE CONTACT STARTED THE IGNITION AND A FEW MOMENTS LATER THE ENGINE STALLED.

WHEN MY WIFE WAS PARKING THE CAR IN A SHOPPING CENTER PARKING LOT, THE ENGINE ROARED (EVEN THOUGH SHE HAD HER FOOT ON THE BRAKE) AND THE VEHICLE JUMPED OVER THE CURB AND STRUCK SMALL BUSHES AND TREES IN THE MEDIAN BETWEEN THE STEIN MART AND HOME DEPT PARKING LOTS CAUSING DAMAGE TO THE FRONT GRILL AND DRIVER SIDE FRONT FENDER. MY WIFE WAS NOT INJURED LUCKILY. HAD THIS EVENT OCCURRED UNDER NORMAL DRIVING CONDITIONS SOMEBODY COULD HAVE BEEN SERIOUSLY INJURED AND OR KILLED DEPENDING UPON THE CIRCUMSTANCES. I HAD A SIMILIAR INSTANCE ABOUT A YEAR AGO WHEN THE CAR SURGED FORWARD WHILE I WAS STOPPED AT A INTERSECTION. MY FOOT WAS ON THE BRAKE AND I GOT THE CAR STOPPED. I CONTINUED TO DRIVE THE CAR AND DID NOT EXPERIENCE ANY FURTHER PROBLEMS. I THOUGHT IT MIGHT HAVE BEEN A STUCK ACCELERATOR LINKAGE THAT CLEARED. I'VE SINCE LEARNED THE...
