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.

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?
ON CERTAIN PASSENGER VEHICLES, THE CIRCUIT BOARD FOR THE CRANK POSITION SENSOR OR CAM POSITION SENSOR MAY HAVE AN IMPROPER SOLDER JOINT DUE TO SOLDER DEFORMATION CAUSED BY HEAT STRESS ACCELERATED BY THE EXISTENCE OF FLUX RESIDUE DURING THE SOLDERING PROCESS.
Consequence & remedy
Consequence: THIS COULD CAUSE THE "SERVICE ENGINE SOON" WARNING LIGHT TO COME ON, CREATE A NO START CONDITION, CAUSE REDUCED ENGINE POWER, OR CAUSE THE ENGINE TO STOP RUNNING WITHOUT WARNING DURING VEHICLE OPERATION, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL REPLACE THE CRANK POSITION SENSORS. CAMSHAFT POSITION SENSOR(S), AND IN SOME CASES, THE VARIABLE TIMING CONTROL SENSOR(S). VEHICLES INVOLVED IN A PREVIOUS RECALL CAMPAIGN, 01V357, ARE ALSO INCLUDED IN THIS NEW CAMPAIGN. THE REPLACEMENT SENSORS USED IN THAT CAMPAIGN ARE ALSO AFFECTED. OWNER NOTIFICATION BEGAN ON DECEMBER 22, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261 OR INFINITI AT 1-800-662-6200.
