2002 INFINITI Q45 — Problems, Recalls & Safety Data

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 THROUGH THE MODEL YEAR, THEY WERE REPLACED WITH ANOTHER TYPE MADE OUT OF BETTER MATERIAL. BEFORE MY MODEL YEAR, THE TYPE USED WAS IN SERVICE I THINK FOR SEVERAL YEARS. THE MID-YEAR REPLACEMENTS WERE USED FOR THE NEXT SEVERAL MODEL YEARS. THIS ALL SUGGESTS THAT THEY KNEW THERE WAS A PROBLEM, BUT AVOIDED PAYING FOR IT OR ISSUING A RECALL. COULD YOU PLEASE INVESTIGATE? THANK YOU

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.

TL* THE CONTACT OWNS A 2002 INFINITI Q45. THE CONTACT STATED THAT THE AIR BAG LIGHT WAS CONSTANTLY ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE DEALER AND MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 90,000. THE VIN WAS NOT AVAILABLE.

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
