2002 INFINITI Q45

ENGINE AND ENGINE COOLING

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.

I HAD A PROBLEM WITH MY CAR, WITH THE TIRES CONSTANTLY LEAKING. I HAD TO FILL THEM WITH AIR ALL THE TIME, HAD THEM CHECKED A NUMBER OF TIMES, AND HAD TO HAVE THE RIMS CLEANED AND REGROUND, ETC., TRYING TO DETERMINE AND SOLVE THE PROBLEM. AFTER INCREDIBLE AGGRAVATION, WE FINALLY TRACKED THE PROBLEM DOWN TO CRACKS IN THE VALVE STEMS. THE VALVE STEMS CONTAINED THE AIR PRESSURE SENSORS AND WERE EXPENSIVE TO REPLACE, PARTS WERE AS MUCH AS $135 OR SO EACH, PLUS LABOR, WHICH COULD BE $200 OR MORE, AND THEN ALL THE TIRE PRESSURE SENSORS HAD TO BE RE-SET - I THINK THE TERM WAS RECALIBRATED OR SOMETHING, WHICH MOST PLACES DIDN'T HAVE EQUIPMENT TO DO OR COULDN'T DO CORRECTLY, AND I ALWAYS ENDED UP HAVING TO GO TO A DEALERSHIP. AT LEAST THEY SOMETIMES DIDN'T CHARGE AS MUCH AS THEY COULD, AS I WAS A CAPTIVE; IF THEY DIDN'T DO IT, NONE OF THE SENSORS WOULD WORK. I DISCOVERED THAT THESE VALVE STEM SENSORS WERE SUBJECT TO CRACKING, AND HAD JUST BEEN PUT ON THE CAR FOR THAT MODEL YEAR. MIDWAY THR

MY CAR RANDOMLY SHUTS OFF IN THE MIDDLE OF DRIVING. FIRST TIME I WAS ON THE HIGHWAY AND IT STARTED RIGHT BACK UP. THEN AGAIN WHEN I GOT HOME. ONE TIME IT HAD A P0340 CODE FOR THE CAMSHAFT POSITION SENSOR, AND I CHANGED IT THREE TIMES IN THE LAST WEEK AND IT STILL SHUTS OFF IN THE MIDDLE OF DRIVING.

WAS ON THE HIGHWAY TAKINGS GRANDKIDS HOME AND THE CAR JUST CUT OFF RIGHT IN THE MIDDLE OF A BUSY HIGHWAY. IT TOOK SEVERAL TRIES TO GET IT TO START AGAIN BUT IT STAYED ON ONLY LONG THOUGH FOR ME TO GET IT ON THE SHOULDER. WE COULD HAVE BEEN IN A SERIOUS WRECK. IT IS ONLY BY THE GRACE OF GOD AND FUNCTIONAL HAZARD LIGHTS THAT WE AND OTHER VEHICLES WEREN'T INJURED. WE HAD TO BE TOWED BECAUSE WE WERE TOO FAR FROM AN EXIT TO RISK TRYING TO DRIVE IT ANY FURTHER! *TR

HAVE HAD 3 HID HEADLIGHT ACTUATOR/BALLAST FAILURES, LEADING TO INOPERATIVE LAMPS (TWO LEFT SIDE, ONE RIGHT SIDE). THE BALLAST IS A HIGH-VOLTAGE TRANSFORMER THAT DRIVES THE DISCHARGE LAMPS. OCCURRENCES AT 24K, 95K, AND 105K MILES. CAR ONLY HAS 110K. FIRST FAILURE REPLACED UNDER WARRANTY. LAST TWO REPAIRS ALMOST $1,000 EA FOR PARTS AND LABOR (MUST REMOVE ENTIRE FRONT FASCIA OF CAR TO REACH BALLAST UNITS). THE PART APPEARS TO BE SERIALLY DEFECTIVE, WITH THE OBVIOUS SAFETY HAZARD OF HAVING ONLY ONE WORKING LIGHT UNTIL TIME AND MONEY FOR REPAIR ARE FOUND. CALCULATED MEAN TIME BETWEEN FAILURE SEEMS TO BE ONE THOUSAND OPERATING HOURS OR LESS. *TR

ON 5/15/08 MY CAR WOULD NOT START, HAD IT TOWED FROM FAYETTEVILLE TO INFINITI DEALER IN RALEIGH. THEY R/R STARTER ASSY TO RESOLVE ISSUE AT NO CHARGE, OLD PART NOT AVAILABLE. ON 7/26/08 CAR WOULD NOT START AGAIN. HAD IT TOWED FROM FAYETTEVILLE TO INFINITI DEALER IN RALEIGH. THEY SAID MOTOR BURNED OUT DUE TO IGNITION SWITCH MALFUNCTION & R/R STARTER ASSY & IGNITION SWITCH TO RESOLVE & CHARGED $1,205.54. I ASKED ABOUT RECALL I FOUND ON NHTSA WEBSITE REGARDING ENGINE & ENGINE COOLING BECAUSE IT STATED THIS COULD CAUSE A NO START CONDITION. THEY DID NOT ACKNOWLEDGE THIS RECALL AND THAT'S WHY THEY CHARGED ME. I WOULD LIKE SOME ASSISTANCE IN DETERMINING IF THIS RECALL IS CAUSING MY CAR TO PERIODICALLY NOT START. THIS SEEMS TO OCCUR EVERY 2 MONTHS. *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.
