Jaguar XJ8 acceleration problems

VEHICLE SPEED CONTROL

AN INCIDENT WITH THE VEHICLE OCCURRED SOMETIME AROUND CHRISTMAS 2011. THE MOTOR SURGED WHILE I WAS FULLY STOPPED AT A STREET LIGHT. THE MOTOR WAS RUNNING, THE CAR WAS IN DRIVE GEAR, AND MY FOOT WAS ON THE BRAKE. I WAS ABLE TO QUICKLY BRING THE CAR UNDER CONTROL. A SECOND EVENT OCCURRED IN 2012, MAY 15TH, AT 11:00 P.M. WHILE I WAS FULLY STOPPED AT A DRIVE THROUGH WINDOW. AGAIN THE MOTOR SURGED, THIS TIME WITH A LOUD SCREECHING SOUND. I APPLIED MAXIMUM BRAKE PRESSURE BUT THE CAR CONTINUED TO SURGE FORWARD, APPROXIMATELY SIX FEET. I SUSTAINED FULL FORCE PRESSURE TO THE BRAKE, THREW THE CAR INTO NEUTRAL GEAR, AND TURNED OFF THE IGNITION IN ORDER TO STOP THE CAR. I IMMEDIATELY DROVE IT HOME WHERE IT HAS REMAINED PARKED---EXCEPT FOR TWO EXCURSIONS TO THE SACRAMENTO JAGUAR DEALERSHIP SERVICE DEPARTMENT.

WHILE DRIVING ON 95 SOUTH IN RI AT APPROX. 60MPH, MY 2004 JAGUAR XJ8 SUDDENLY LOST ALL POWER, INCLUDING ENGINE, STEERING AND BRAKING ABILITIES. IT NEARLY RESULTED IN A MULTI CAR FATAL ACCIDENT FROM BEING HIT FROM BEHIND. THE DEALER STATED, AFTER A SYSTEMS CHECK, THAT AN ACCELERATOR PEDAL SENSOR HAD FAILED RESULTING IN A $500.00 REPLACEMENT COST. THIS IS A VERY DANGEROUS DEFECT THAT SHOULD HAVE BEEN PART OF A SAFETY RECALL.

2004 JAGUAR XJ8 . CONSUMER STATES UNINTENDED ACCELERATION *TGW THE CONSUMER STATED WHILE APPROACHING A FOUR-WAY STOP, HE BEGAN TO SLOW DOWN. HE WAS DRIVING SLOWLY, WHEN HE REMOVED HIS RIGHT FOOT FROM THE ACCELERATOR AND BEGAN TO PRESS DOWN ON THE BRAKE PEDAL. INSTEAD OF THE VEHICLE GRADUALLY SLOWING DOWN, THE ENGINE RACED TO AN EXTREMELY HIGH RPM. HE PRESSED FURTHER ON THE BRAKE, BUT THE VEHICLE LUNGED FORWARD ABOUT 30 FEET BEFORE STOPPING JUST SHORT OF A TRUCK CROSSING IN THE INTERSECTION. THE SAME SITUATION HAPPENED AGAIN IN A PARKING LOT WHICH CAUSED THE CONSUMER T RUN UP ON A CONCRETE STOP ALMOST STRIKING A PEDESTRIAN. WHEN THE CONSUMER ARRIVED HOME LATER IN THE EVENING, THERE WAS A RECALL NOTICE IN THE MAIL AND HE IMMEDIATELY TOOK THE VEHICLE TO THE DEALER. THE DEALER CHECKED FOR THE RECALL AND THE PROBLEM, BUT THEY WERE UNABLE TO FIND ANYTHING WRONG. THE SAME INCIDENT HAPPENED AGAIN WHERE THE CONSUMER ALMOST HIT A VEHICLE APPROACHING FROM HIS LEFT. A NOTIFICATION LIGHT ILLUMINATED WHICH READ DSC NOT AVAILABLE. IN EACH INSTANCE, THE CONSUMER WAS TRAVELING NO MORE THAN 5 TO 10 MPH. 8JB

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

JAGUAR 2004 FAILURE OF ACCELERATOR SENSOR WHILE DRIVING ON I-40/I75 IN KNOXVILLE, TN RESULTING IN A INSTANT SHUTDOWN OF ENGINE THAT COULD HAVE RESULTED IN A FATAL OR NEAR FATAL ACCIDENT BY BEING "RUN OVER" BY TRAFFIC FROM THE REAR. RESULTED IN A 900 DOLLAR REPAIR AS SENSOR WAS A PART OF THROTTLE BODY THAT ACCORDING TO DEALER HAD TO BE REPLACED. I AM QUESTIONING THAT JAGUAR CAN HAVE A CAR ON THE ROAD THAT DOES NOT HAVE A BACKUP FOR THIS TYPE OF FAILURE.

I WAS BRAKING INTO A PARKING SPOT AT THE BANK WHEN WITHOUT NOTICE MY VEHICLE ACCELERATED WILDLY. I PRESSED ON THE BRAKE WITH ALL OF MY WEIGHT TO STOP FROM LITERALLY RAMMING MY VEHICLE INTO THE SIDE OF THE BANK. THE ROAR OF THE TRANSMISSION WAS LIKE SOMEONE WAS STEPPING FULL FORCE ON THE GAS PEDAL, BUT MY FOOT WAS SOLIDLY ON THE BRAKE AND NOT EVEN TOUCHING THE GAS PEDAL. IT WAS TERRIFYING. IF THERE HAPPENED TO BE SOMEONE WALKING ON THE SIDEWALK IN FRONT OF ME, I WOULD HAVE HIT THEM. I WOULDN'T HAVE BEEN ABLE TO AVOID IT. AS IT WAS, THE ONLY WAY I COULD STOP THE CAR FROM DRIVING FORWARD WAS TO SHIFT THE CAR INTO PARK AND THEN TURN IT OFF. AFTER WAITING A WHILE, I RESTARTED THE CAR AND CAUTIOUSLY DROVE HOME WITHOUT FURTHER INCIDENT. THIS PROBLEM WITH SUDDEN ACCELERATION IS SO SERIOUS. IT'S ONLY A MATTER OF TIME BEFORE SOMEONE IS SERIOUSLY INJURED OR KILLED....PLEASE LOOK INTO IT!

I WAS BRAKING INTO A PARKING SPOT AT THE LOCAL BANK WHEN WITHOUT NOTICE MY VEHICLE ACCELERATED WILDLY. I PRESSED ON THE BRAKE WITH ALL OF MY WEIGHT AS IF MY LIFE DEPENDED ON IT. THE ROAR OF THE TRANSMISSION WAS LIKE SOMEONE WAS STEPPING FULL FORCE ON THE GAS PEDAL, BUT MY FOOT WAS SOLIDLY ON THE BRAKE AND NOT EVEN TOUCHING THE GAS PEDAL. IT WAS TERRIFYING. I COULD HARDLY KEEP FROM DRIVING INTO THE SIDE OF THE BANK. IF THERE HAPPENED TO BE SOMEONE WALKING ON THE SIDEWALK IN FRONT OF ME, I WOULD HAVE HIT THEM. I WOULDN'T HAVE BEEN ABLE TO AVOID IT. AS IT WAS, THE ONLY WAY I COULD STOP THE CAR FROM DRIVING FORWARD WAS TO SHIFT THE CAR INTO PARK AND THEN TURN IT OFF. AFTER WAITING A WHILE, I RESTARTED THE CAR CAUTIOUSLY, AND DROVE IT HOME WITHOUT INCIDENT.

WHILE STOPPED AT A RED LIGHT, FOOT ON BRAKE, SHIFT IN DRIVE, VEHICLE WENT INTO VERY HIGH RATE OF ACCELERATION AND LUNGED UNCONTROLLABLY FORWARD. LUCKILY THERE WAS NO VEHICLE IN FRONT OF ME AS I WOULD HAVE CRASHED INTO IT. I NOTIFIED THE DEALER AND HE REFERRED ME TO A LOCAL DEALER. THE VEHICLE WAS INSPECTED AND I WAS ASSURED THAT THEY FOUND NOTHING WRONG. THIS WAS A VERY SCARY SITUATION AND THE MANUFACTURER SHOULD SERIOUSLY LOOK INTO THE MATTER.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

THE FIRST INCIDENT WAS AT A PARKING LOT BOOTH. I HAD MY FOOT ON THE BREAK AND THE ENGINE RAISED FOR ABOUT TEN SECONDS LIKE IF SOMEONE WAS PRESSING THE GAS. IT SOUNDED LIKE THE ENGINE WAS GOING TO BLOW UP. I HAD TO PRESS THE BREAK PEDAL HARD TO KEEP IT FROM MOVING AND HITTING THE GATE. THE SECOND INCIDENT WAS APPROXIMATELY 2 WEEKS LATER AT AN INTERSECTION. I WAS STOPPED AT A LIGHT WITH MY FOOT ON THE BREAK WHEN THE ENGINE STARTED RAISING AGAIN LIKE IF SOMEONE WAS PRESSING ON THE GAS. I LOOKED DOWN TO SEE IF THE RUG WAS ON THE WAY. THERE WAS NOTHING PRESSING ON THE GAS PEDAL. THIS TIME IT DID NOT STOP BY ITSELF; I HAD TO SHIFT GEARS BECAUSE IT WAS HARD TO HOLD THE BREAK. I PUT IT ON PARK AND TURNED OFF THE CAR. I WAS ABLE TO START THE CAR BACK ON BUT IT WOULD NOT SHIFT GEARS. IT WAS TOWED TO THE DEALERSHIP. RUSNAK-PASADENA KEPT IT FOR 2 WEEKS. THEY REPLACED THE TRANSMISSION AND DETERMINED THAT THERE WAS NOTHING WRONG WITH THE CAR. THEY SUGGESTED I HAD MY FOOT ON BOTH PEDALS AND WANTED TO GIVE ME INSTRUCTIONS ON HOW TO USE ONE PEDAL AT A TIME. I DROVE THE CAR THREE MORE TIMES (LOCAL DRIVING ONLY). THE LAST TIME WAS YESTERDAY AFTERNOON. I WAS GETTING OUT OF A PARKING LOT, BEHIND TWO CARS, ALL OF A SUDDEN THE ENGINE STARTED TO RAISE AGAIN. I PLACED IT IN PARK AND THE ENGINE STOPPED RAISING. I DROVE THE CAR HOME AND STARTED LOOKING AT ANY OTHER SUCH REPORTS FOR THIS CAR. I FOUND TWO INCIDENTS IN YOUR FILES. ONE WAS REPORTED ON 01/26/05 (REFERENCE #1018965), THE OTHER WAS REPORTED ON 09/20/06 (REFERENCE #10168741).

OVER THE PAST SIX (6) MONTHS, THE VEHICLE HAS STALLED ON THE HIGHWAY APPROXIMATELY 4 TIMES. HAD TO DRIFT ONTO THE SHOULDER, PUT VEHICLE IN PARK TO START CAR AGAIN. THAT IS A VERY DANGEROUS SITUATION TO BE ON AN INTERSTATE TRAVELING AT A SPEED OF 50 AND ABOVE HAVING TO DRIFT ACROSS LANES WITH ABSOLUTELY NO POWER. AS OF THIS PAST WEEKEND, I STARTED THE CAR, THE AIRBAG LIGHT WOULD NOT GO OFF. THE NEXT DAY, THE CAR WAS MAKING A HORRIBLE NOISE AND ONCE AGAIN THE AIRBAG LIGHT WAS ON. THE NOISE SOUNDED AS IF SOMETHING WAS LOOSE UNDERNEATH THE HOOD. THE CAR SOUNDED SO HORRIBLE, I HAD IT TOWED VERSUS DRIVING IT TO THE SHOP. I GOT THE BAD NEWS THAT THE ENGINE HAS NO COMPRESSION AND NEEDS TO BE REPLACED. THE MECHANIC HAS NO IDEA WHAT WENT CAUSED THIS. I WILL HAVE TO GET ANOTHER ENGINE OR LET THE MECHANIC BREAK THE CURRENT ENGINE DOWN TO SEE WHAT PARTS CAN BE RE-USED. I READ ON ANOTHER WEBSITE THAT A FEW PEOPLE HAD TO HAVE ENGINES REPLACED ON THE 1998 JAGUARS FOR NO APPARENT CAUSE. THIS IS RIDICULOUS AND NO FAULT OF MINE. I HAVE KEPT UP THE MAINTENANCE. I FOUND THIS LINK WHICH SUGGESTS POSSIBLE ENGINE FAILURE CAUSES HTTP://WWW.JAGSERVICE.NET/JAGUAR_V8_SECONDARY_TENSIONERS.HTM.

RECALL REMEDY FAILED. AFTER THE RECALL FOR THE THROTTLE WAS PERFORMED THE RECALL DEFECT HAPPENED AGAIN. *AK RECALL CAMPAIGN# 98V022000. JAGUAR STATED THAT THE THEY WERE NOT RESPONSIBLE FOR ANY FURTHER CORRECTIVE ACTION. THE VEHICLE CONTINUED TO STALL. (MORE FREQUENTLY) IN OTHER ATTEMPTS TO REMEDY THE STALLING PROBLEM, THE DEALER WOULD REPROGRAM THE ECM (ELECTRONIC CONTROL MODULE) AND SUGGESTED THAT THE VEHICLE WAS FINE. THE SOFTWARE FIX RECOMMENDED BY JAGUAR HAD NOT CORRECTED THE PROBLEM. THE CONSUMER ALSO STATED THAT A CHIRPING NOISE WOULD OCCUR UPON DECELERATION. THE FRONT BRAKE SHROUD WAS ADJUSTED. JAGUAR INVESTIGATED AND CHANGED AN IDLER PULLEY AND THE SERPENTINE BELT BUT THE CHIRPING NOISE WAS STILL PRESENT. THE PROBLEM WAS DIAGNOSED AS A BAD DIFFERENTIAL AT 80K MILES. *SC
