2002 Infiniti Q45

RIGHT REAR TIRE SUDDENLY BEGAN TO LOSE PRESSURE, AS MUCH AS 5 PSI IN ONE MILE OF FREEWAY DRIVING. I KEPT STOPPING TO AIR UP TIRE, CONFIRMING LOW PRESSURE WITH ACCURATE BOURDON TUBE-TYPE GAUGE. AFTER FOUR STOPS TO AIR UP, PROBLEM QUIT. WHEN I REACHED DESTINATION CITY, SET UP SERVICE APPT. WITH LOCAL INFINITI DEALER. AFTER FOUR DAYS OF A LONG WEEKEND, INCLUDING SLOW-SPEED AND FREEWAY DRIVING OF OVER 200 MILES, PRESSURE LOSS HAD QUIT. CANCELLED DEALER APPOINTMENT. THREE MONTHS LATER, PROBLEM OCCURRED AGAIN. HAD TIRE CHECKED AT NTB, NO LEAKS FOUND. TIRE DISMOUNTED, CHECKED ON INSIDE, NO DEFECTS OR PUNCTURES OR BLISTERS FOUND, WHEEL IN GOOD SHAPE, TIRE REMOUNTED. ONE MONTH LATER, PROBLEM OCCURRED AGAIN, THIS TIME LOSING 10 PSI IN TWO MILES OF FREEWAY DRIVING. AIRED UP. LOST 5 PSI. CHANGED TO SPARE. DEALER MOUNTED NEW TIRE. PRESSURE DROPPED TWO DAYS LATER. DEALER INSTALLED NEW WHEEL (COULDN'T EXACTLY MATCH EXISTING COLOR--GREAT ON A $60K CAR.) AND REMOTE PRESSURE SENSOR. PROBLEM CURED. COST: NEW TIRE--$350, TOSSED TIRE WITH 30K LEFT ON IT (SUSPECTED OF BEING CAUSE)--$350, NEW TAKE-OFF WHEEL--$800, NEW SENSOR--$260. TOTAL COST, INCLUDING MECHANIC AND TRASHED GOOD TIRE--$2,000. NO DIAGNOSIS EVER OFFERED. *TR

1 - THERE IS UP TO A TWO SECOND DELAY WHEN QUICK ACCELERATION IS REQUIRED. AT TIMES IT FEELS AS IF THE ENGINE COMPLETELY STALLED. 2 - THE VEHICLE OFTEN WILL NOT DOWNSHIFT TO SLOW THE VEHICLE ON A HILL. I COULD BE IN 5TH GEAR AT AROUND ONLY 1800 RPM, AND WHEN I DOWNSHIFT TWICE, IT WILL NOT GO TO 3RD. I OFTEN HAVE TO DOWNSHIFT UP TO 6 TIMES FOR IT TO RESPOND AND SWITCH TO THIRD. I NEED TO TAKE MY EYES OFF THE ROAD TO CONSTANTLY CHECK IF I'M IN THE GEAR I SELECT. 3 - THE PARKING/EMERGENCY BREAK WILL NOT HOLD THE FULLY LOADED VEHICLE ON A HILL. IF THE TRANSMISSION IN PARK FAILS, THE VEHICLE WILL ROLL. ALL ISSUES ARE CONSIDERED TO BE NORMAL BY THE MANUFACTURER. THEY CORRECTED THE PROBLEM ON THEIR NEW 2005 VERSION AND REFUSE TO DO SO ON MY VEHICLE.

THE CONSUMER WAS INFORMED BY THE INFINITY CSR THAT BASED ON THEIR RECORDS, THE CRANK POSITION SENSOR WELD RECALL 03V455000 WASN'T PERFORMED. PRIOR TO CONTACTING THE MANUFACTURER, THE CONSUMER HAD TAKEN THE VEHICLE TO THE DEALERSHIP TO HAVE THE RECALL BREPAIRSPERFORMED AND WAS TOLD WHEN THEY PICKED THE VEHICLE THAT THE RECALL WAS DONE.*AK

CONSUMER AND THE DEALERSHIP NOTICED THAT ENGINE WAS CONSUMING 2 AND A HALF QUARTS OF OIL EVERY 4400 MILES. ALSO, VEHICLE HAD BRAKE ROTORS PROBLEMS. *AK WHEN THE SECOND OIL CONSUMPTION TEST WAS DONE FOR 33000 MILES THE VEHICLE USED ONE AND A HALF QUARTS OF OIL. HEAVY BLUE SMOKE EMITS FROM THE EXHAUST PIPE DURING INITIAL START UP. *NM

A FEW WEEKS AFTER PURCHASE OF MY 2002 INFINITI Q45 (UNDER 4000 MILES)DURING AN EXTENDED ROAD TRIP, I LOST ALL CONTROLS ON MY A/C AND AUDIO SYSTEMS.IN A SEPARATE INCIDENT, I ALSO LOST CONTROL OF MY CRUISE CONTROL SYSTEM. AFTER STOPPING AND RESTARTING THE CAR, THE SYSTEMS WERE RE- ACTIVATED. WITH THE EXTENSIVE COMPUTERIZED SYSTEMS ON THIS CAR, THIS COULD HAVE BEEN A MUCH MORE SERIOUS PROBLEM! I REPORTED THIS PROBLEM TO MY DEALER BUT THEY WERE NOT ABLE TO REPLICATE THE PROBLEM. ON ANOTHER LONG TRIP,A FEW THOUSAND MILES LATER,BOTH PROBLEMS REOCCURRED. THIS TIME MY DEALER ASKED TO KEEP THE CAR FOR SEVERAL DAYS DURING WHICH TIME THE SITUATION DID REPLICATE. THE TECHNICIANS TRACED THE PROBLEM TO A DEFECTIVE RADIO(?) WHICH THEY REPLACED. LESS THAN 100 HUNDRED MILES LATER ON A HIWAY TRIP, BOTH CONDITIONS REOCCURRED.THE CAR IS BACK IN THE SHOP!I HAVE ALERTED INFINITI CONSUMER AFFAIRS FOR THE SECOND TIME OF THIS PROBLEM . THEY ARE SAYING THEY CAN'T FIX IT, IF THEY CAN'T FIND THE PROBLEM!HELLO!!!ANY ADVICE WOULD BE APPRECIATED. I CERTAINLY DO NOT FEEL SAFE DRIVING THIS CAR. WHAT CAN HAPPEN NEXT?

MY "2002" INFINITI AUTOMOBILE MODEL Q45 WAS REAR ENDED BY ANOTHER AUTO WHILE TRAVELING THROUGH AN INTERSTATE CONSTRUCTION ZONE. MY CAR WAS MOVING AT THE TIME AND I WAS DRIVING. THE FORCE OF THE COLLISION BROKE EITHER MY SEAT BACK OR ITS ELECTRIC OPERATING ASSEMBLY TO THE EXTENT THAT THE SEAT BACK COLLAPSED REARWARD AND AS A RESULT I WAS BARELY ABLE TO REACH THE BRAKE PEDAL IN ORDER TO BRING THE CAR UNDER CONTROL AND STOP. THIS COULD HAVE MADE WHAT TURNED OUT TO BE MAJOR ACCIDENT A CATASTROPHIC ONE SIMPLY BECAUSE OF AN INFERIOR DESIGNED SEAT.*AK

LOW TIRE PRESSURE WARNING LIGHT CAME ON ALONG WITH LCD INFORMATION THAT VEHICLE NEEDED TO BE TAKEN TO DEALER FOR SERVICE; SOMETHING WAS WRONG WITH THE REMOTE TIRE PRESSURE-SENSING SYSTEM. IT TOOK TWO TRIPS TO THE DEALERSHIP, A TOTAL OF FIVE DAYS, AND A LOT OF TIME WITH THE MECHANIC EITHER ONLINE OR ON THE TELEPHONE WITH AN INFINIT "HOT LINE" ELECTICAL SPECIALIST TO DIAGNOSE THE PROBLEM: ONE DEFECTIVE TIRE PRESSURE SENSING GAUGE. TROUBLE IS, THE SAME THING HAD HAPPENED APPROXIMATELY ONE YEAR AGO, WHEN THE VEHICLE WAS ONLY ABOUT TWO MONTHS OLD. AT THAT TIME, THE DEALERSHIP WAS ABLE TO DIAGNOSE THE PROBLEM AND SIMPLY REPLACED A TIRE PRESSURE GAUGE. PROBLEM SOLVED. WHY, WITH THIS CAR'S PREVIOUS HISTORY, DID IT TAKE FIVE DAYS AND SEVERAL MINDS WORKING TOGETHER TO DETERMINE THAT MY CAR WAS SUFFERING FROM THE EXACT SAME PROBLEM AS A YEAR EARLIER?

VEHICLE UNSAFE TO DRIVE AT NIGHT DUE TO THE SHORT DISTANCE THAT THE HEADLIGHTS ILLUMINATE. *PH THE CONSUMER REQUESTED THAT THE DEALER ADJUST THE HEADLIGHTS BUT WAS TOLD THAT THEY COULD NOT BE ADJUSTED. THE CONSUMER CONTACTED THE MANUFACTURER WHO INDICATED THAT THE CAR MEETS GOVERNMENT SPECIFICATIONS WHICH WERE ENFORCED AT THE TIME OF PRODUCTION. *NM

I OWN A 2002 INFINITI Q45, WHICH WAS PURCHASED NEW. SINCE TAKING DELIVERY OF THE VEHICLE ON AUGUST 8, 2002, I HAVE REPEATEDLY COMPLAINED OF VIBRATION AND VIBRATION RELATED ISSUES, BUT THE DEALERSHIP WAS NEVER ABLE TO CORRECT THE PROBLEM. ON MY LATEST VISIT, DURING THE 22500-MILE SERVICE, THE DEALERSHIP INFORMED ME THAT ALL FOUR OF MY FACTORY WHEELS WERE BENT. THE TECHNICIAN AT THE DEALERSHIP SAID THAT THEY SEE THIS REGULARLY AND THAT IT IS CAUSED BY IMPERFECTIONS IN THE ROAD SURFACEPOTHOLES, BRICK ROADS, UNEVEN PAVEMENT, ETC. I EXPLAINED THAT I HAVE NOT HIT ANY POTHOLES OR UNEVEN PAVEMENT AND THE BRICK ROADS THAT I HAVE DRIVEN ON ARE IN GOOD CONDITION, BUT THE DEALERSHIP REFUSES TO REPAIR OR REPLACE MY WHEELS. BEING THAT THE DEALERSHIPS TECHNICIAN TOLD ME THIS IS A COMMON PROBLEM WITH MY CAR, I BELIEVE THAT THE FACTORY INFINITI 18 WHEELS ARE MADE OF AN ALUMINUM ALLOY, WHICH IS TOO SOFT AND BENDS TOO EASILY UNDER NORMAL ROAD CONDITIONS. FURTHERMORE, INFINITI OWNERS MAY BE UNAWARE THAT THEIR WHEELS ARE BENT AND UNSAFE AND CONTINUE TO DRIVE ON THEM. *PH
