2004 Infiniti QX56

MY 2004 INFINITY Q56 ENGINE CUTS OFF GOING DOWN THE ROAD. DEALER IS AWARE OF A PROBLEM WITH SEVERAL YEAR MODELS DOING THIS SAME THING. ALL POWER IS LOST BRAKES , STEERING ECT. HAVE HAD 4 COMPUTER BOARDS REPLACE AND GOING BACK FOR ANOTHER TRY OCT.25-2010. INFINITY CONSUMER AFFAIRS HAS BEEN CONTACTED BUT EVEN THOUGH THEY ARE CONCERNED THEY ARE NOT SURE OF A FIX. WHAT WILL IT TAKE TO GET HELP, A BAD CRASH OR TWO? IF YOU TYPE IN PROBLEMS WITH Q56 CUTTING OFF WHILE GOING DOWN THE ROAD YOU WILL SEE THAT THE INTERNET HAS A GROUP OF PEOPLE EXPERIENCING THIS SAME SCARY ISSUE. THANK YOU FOR LOOKING INTO THIS. I MYSELF HAVE HAD A FEW CLOSE CALLS TRYING TO GET THE CAR OFF THE ROAD SAFELY. FIRST INCIDENT JUNE 2007 LAST INCIDENT OCT. 20 , 2010. *TR

TL* THE CONTACT OWNS A 2004 INFINITI Q-X56. THE VEHICLE WAS HAVING A ROUTINE OIL CHANGE WHEN THE DEALER INFORMED HIM THAT THE FRONT BRAKE PADS WERE DEFECTIVE. THE BRAKE PADS WERE REPLACED AT THAT TIME. WHILE DRIVING HOME FROM THE DEALER AT UNKNOWN SPEEDS, THE BRAKES DID NOT FEEL NORMAL AND TOOK THE VEHICLE BACK TO THE DEALER. THE DEALER ADVISED THAT THE BRAKES WERE NORMAL AND WOULD FEEL UNCOMFORTABLE UNTIL THEY WERE BROKEN IN. THE NEXT DAY WHILE DRIVING AT 55 MPH AND APPLYING THE BRAKES, THE BRAKES WOULD NOT ENGAGE AND THE CONTACT CRASHED INTO A GUARD RAIL. THE CONTACT SUFFERED INJURIES TO HIS RIGHT FOOT. THE VEHICLE WAS DESTROYED. THE CONTACT WAS TRANSPORTED TO THE HOSPITAL AND ONE THIRD OF HIS FOOT WAS AMPUTATED DUE TO THE INJURY SUSTAINED IN THE CRASH. A POLICE REPORT WAS AVAILABLE. THE MANUFACTURER SENT AN INVESTIGATOR TO FURTHER ASSESS THE FAILURE IN THE VEHICLE BUT WAS RULED AS INCONCLUSIVE DUE TO THE EXTENSIVE DAMAGE TO THE VEHICLE. THE MANUFACTURER ADVISED THE CONTACT TO ADDRESS THE FAILURE WITH HIS INSURANCE COMPANY. THE FAILURE MILEAGE WAS 100,000.

TLA* THE CONTACT OWNS 2004 INFINITY QUIZ. WHILE DRIVING AT APPROXIMATELY 30 MPH, WHEN THE BRAKE PEDAL WAS APPLIED IT WENT DOWN TO THE FLOOR, MADE A LOUD NOISE AND FAILED TO OPERATE. THE ABS BRAKE LIGHT ILLUMINATED AFTER THE FAILURE OCCURRED. THE CONTACT SHIFTED THE GEAR FROM FOURTH GEAR TO FIRST GEAR TO SLOW THE VEHICLE DOWN. THE MANUFACTURER TOOK A REPORT AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO THE DEALER TO BE DIAGNOSED, BECAUSE THERE WAS NOT A RECALL OR A TECHNICAL SERVICE BULLETIN FOR THE BRAKE FAILURE. THE FAILURE MILEAGE WAS 89,000 AND THE CURRENT MILEAGE WAS 99,008. UPDATED 10/22/10 *BF THE CONSUMER STATED THERE IS A FAILURE IN THE SENSOR INSIDE THE BRAKE BOOSTER. UPDATED 10/26/10

AT APPROXIMATELY 8K MILES THE DEALER REPLACED THE ROTORS AND CALIPERS PER THEIR SERVICE BULLETIN WHICH SEEMED TO SOLVE THE PROBLEM. SINCE THEN, PERIODICALLY WHILE DRIVING, THE BRAKE LIGHT WILL ILLUMINATE WHEN BRAKES ARE APPLIED AND THE ABS SYSTEM ACTIVATES AND THE BRAKES BEGIN TO GROAN, ARE SPONGY, HAVE LESS THAN 10% BRAKING POWER. THIS HAS HAPPENED TO ME 5 TIMES OVER 90K MILES. ALTHOUGH I DID NOT MAKE THE CONNECTION AT THE TIME, I BELIEVE THAT IT WAS THE CAUSE OF A REAR END COLLISION THAT I WAS INVOLVED IN 2008 WHEN I ATTEMPTED TO BRAKE THE CAR ON THE FREEWAY BUT FELT THAT THE CAR TOOK MUCH TOO LONG TO COME TO A COMPLETE STOP WHEN I QUICKLY SLAMMED ON THE BRAKES.THE VEHICLE CONTINUES THESE SYMPTOMS UNTIL THE IGNITION IS TURNED OFF. WHEN RESTARTED, THE PROBLEM IS RESOLVED. IT HAS MOSTLY ONLY OCCURRED TO ME WHILE DRIVING AWAY FROM A PARKING SPOT BUT YESTERDAY IT OCCURRED WHILE I WAS DRIVING ON THE FREEWAY AT SPEED EXCEEDING 50 MPH. I WAS ONLY ABLE TO STOP THE VEHICLE BY DOWNSHIFTING MY AUTOMATIC TO 1ST GEAR WHILE ATTEMPTING TO ACTIVATE THE EMERGENCY BRAKE. I WAS FORTUNATE THAT I WAS ON A LEVEL FREEWAY AND NOT GOING DOWN A STEEP INCLINE. AFTER I WAS ABLE TO SAFELY PULL OVER, THE IGNITION WAS TURNED OFF AND THE CAR WAS RESTARTED WITH NO BRAKE PROBLEMS. TODAY I TOOK THE CAR INTO THE INFINITI DEALER AND THEY SAID THAT IT WAS A 'COMMON PROBLEM' BUT NOT A RECALL AND THAT THEY WOULD TRY TO REPROGRAM THE COMPUTER. REPROGRAMMING DID NOT WORK AND THEY SAID I WOULD NEED A NEW ABS BOOSTER PUMP AT A COST TO ME OF $925. I LOOKED UP THE PROBLEM ON CONSUMER WEBSITES AND FOUND THAT THE PROBLEM IS FAIRLY COMMON WITH BOTH THE 2004 NISSAN TITAN AND ARMADA AND THE INFINITI QX56. IT SEEMS TO BE A PROBLEM WITH THE C1179 CODE. WHAT I DISCOVERED IS THAT ANY CONSUMERS STILL HAD THE PROBLEM EVEN AFTER THEY REPROGRAMMED THE COMPUTER AND REPLACED THE ABS BOOSTER PUMP. A SERVICE BULLETIN REPAIR EXISTS FOR THE 2004 NISSAN TITAN (NHTSA ITEM NUMBER: 10020026). THIS IS A SERIOUS SAFETY CONCERN. *TR

AT THE BEGINNING OF JUNE 2008, I NOTICED SPOTS ON MY GARAGE FLOOR UNDER THE CAR, TOWARDS THE FRONT OF THE ENGINE; I THOUGHT IT MUST BE THE OIL FILTER AND IT NEEDED TO BE TIGHTENED. I CONTINUED TO NOTICE THIS FOR THE FOLLOWING WEEKS. I WENT UNDER THE VEHICLE AND NOTICED THAT THE LEAKY FLUID HAD CASCADED ALL UNDERNEATH THE VEHICLE. I WENT INTO HAVE IT SERVICED, DEALER SAID THAT IT WAS ATF FLUID, DEALER TIGHTENED A CLAMP. PROBLEM CONTINUED TO PERSIST, WENT INTO SERVICE, DEALER REPLACED HOSE. PROBLEM CONTINUED TO PERSIST, WENT INTO SERVICE, DEALER SAID THEY NEEDED TO REPLACE THE ENTIRE RADIATOR SYSTEM DUE TO DESIGN DEFECT IN THE HOSE AND CLAMP CONNECTION...TOTAL COST FOR THIS REPAIR $1086.96. WROTE LETTER TO INFINITY CONSUMER AFFAIRS, STATING I SHOULD BE REIMBURSED FOR THIS REPAIR AS IT WAS A NHTSA 10012879 BULLETIN AND MANUFACTURE DESIGN FAILURE.....THEIR REPLY: "SORRY CANT HELP YOU". THEY WOULD ONLY COVER THIS REPAIR TO THE LEAKING ATF FLUID IF THE CAR WAS UNDER WARRANTY ((I NOTICED THE PROBLEM WHILE MY CAR WAS UNDER WARRANTY, BUT TOOK IT IN TO HAVE THE WORK DONE WITHIN 60DAYS OF MY WARRANTY EXPIRING, WITH ONLY 40K MILES ON THE CAR ' I THOUGHT IT WAS JUST THE OIL FILTER NEEDING TO BE TIGHTENED)) THIS IS A SAFETY ISSUE THAT THE MANUFACTURE NEEDS TO COVER IN FULL, REGARDLESS OF THE CAR BEING IN OR OUT OF WARRANTY; IF THIS LEAK CONTINUED TO PERSIST, THE FLUID COULD COME IN CONTACT WITH THE EXHAUST MANIFOLD OR CATALYTIC CONVERTER AND CAUSE A FIRE. *TR

INFINITI QX56: INTELLIGENT CRUISE CONTROL ON VEHICLE CAUSES ALL OF INSTRUMENT PANEL TO MALFUNCTION AND THE VEHICLE TO SUDDENLY STOP RUNNING. THIS OCCURS EVEN WHEN THE CRUISE CONTROL IS NOT BEING USED. THE LASER GUIDED SYSTEM CAUSES ELECTRICAL MALFUNCTIONS THROUGHOUT THE VEHICLE CAUSING GAUGES TO FLUCTUATE RANDOMLY AND ALERT LIGHTS TO GIVE FALSE READINGS. DEALER DEEMS IT A "POOR DESIGN" AND CONSIDERS VEHICLE UNSAFE TO DRIVE UNLESS THE SYSTEM IS REPLACED. THE SYSTEM IS BEING REPLACED WITH THE EXACT SAME PART SO THE LIKELIHOOD OF RECURRENCE IS VERY HIGH. MULTIPLE VEHICLES AFFECTED; DEALER HAD SEVERAL VEHICLES IN THE SHIP WITH THE EXACT SAME PROBLEM. *TR

TL*THE CONTACT OWNS A 2004 INFINITI QX56. WHILE EXITING THE HIGHWAY AT 50 MPH, THE VEHICLE SHUT OFF AS IF THE IGNITION WAS TURNED OFF. THERE WAS NO POWER STEERING OR BRAKING ABILITY. THE CONTACT COASTED TO THE SIDE OF THE ROAD. AFTER APPROXIMATELY 2-3 ATTEMPTS, THE VEHICLE RESTARTED. THE VEHICLE STOPPED A SECOND TIME APPROXIMATELY 2-5 MINUTES LATER. THE VEHICLE RESTARTED AGAIN. APPROXIMATELY 20 MINUTES LATER, THE VEHICLE SHUT OFF FOR THE THIRD TIME. ON THE SECOND CRANK, THE VEHICLE RESTARTED. THE CONTACT DROVE HOME AND CALLED THE DEALER TO SCHEDULE A REPAIR APPOINTMENT. WHEN HIS WIFE DROVE THE VEHICLE, THE FAILURE RECURRED, BUT THE VEHICLE WOULD NOT START. THE VEHICLE WAS TOWED TO THE DEALER AND THEY STATED THAT THERE WAS AN INTERNAL FAILURE OF THE IPDM. THEY REPLACED THE IPDM WITH GOODWILL PARTS. THE CURRENT MILEAGE WAS 56,012 AND FAILURE MILEAGE WAS APPROXIMATELY 55,944. UPDATED 10-07-08 *BF UPDATED 10/09/08. *JB

I HAVE HAD MY VEHICLE IN FOR REPAIR A TOTAL OF 6 TIMES FOR THE BRAKES. 6/05 AND 9/05 FOR A SHUDDER AND SQUEAK ISSUE. 4/06, 8/06, 9/06 AND 11/06 FOR A COMPLETE BRAKE FAILURE ISSUE. THE DEALER DOES NOT SEEM TO BE ABLE TO FIX THE PROBLEM AND IT IS A SAFETY HAZARD TO DRIVE THE VEHICLE. THERE IS NO WARNING WHEN THE BRAKES FAIL. *JB

I PURCHASED AN INFINITI QX56 IN MAY 2004 HAD BRAKES PROBLEMS AFTER ONLY 3,000 MILES BROUGHT VEHICLE TO DEALER IN AUGUST 2004 THEY REPLACED THE ROTORS AND CALIPERS. HAD THE SAME PROBLEM AGAIN IN DECEMBER 2004 AT 6,700 MILES, DEALER AGAIN REPLACED ROTORS. AGAIN IN MAY 2005 AT 10,321 MILES BROUGHT THE VEHICLE BACK TO THE DEALER THEY AGAIN REPLACED THE ROTORS AND BREAK PADS, I WAS TOLD THAT THERE WAS A DEFECT WITH THESE VEHICLES BRAKING SYSTEM BUT THAT THEY WERE GOING TO UPDATE THE ROTORS AND THAT WILL CORRECT THIS PROBLEM FOR GOOD. IN MAY 2005 BROUGHT THE VEHICLE BACK FOR THE INSTALLATION OF THE UPDATED ROTORS BUT NOW AT 19,000 MILES, I'M STILL HAVING BRAKE PROBLEMS THE STEERING WHEEL SHAKES WHEN APPLYING THE BRAKES OR WHEN DRIVING OVER ROUGH PAVEMENT. CALLED DEALER TODAY TO FILE COMPLAINT. I WOULD LIKE TO KNOW IF THE LEMON LAW APPLIES UNDER THESE CIRCUMSTANCES. *JB
