This Problem Across All Years
WHEN COLD OUTSIDE, MY 2001 INFINITI I30 RECENTLY STARTED LOOSING POWER BRAKE BOOST AFTER THE BRAKE PEDAL IS DEPRESSED TWO TIMES. AN INTERNET SEARCH REVEALED THAT THIS IS A COMMON PROBLEM WITH VARIOUS NISSAN/INFINITI MODELS. THE PROBLEM, WHICH I VERIFIED THIS MORNING IS A CHECK VALVE IN THE VACUUM LINE COMING FROM THE INTAKE MANIFOLD TO THE BRAKE BOOSTER. I STARTED THE CAR, DEPRESSED THE BRAKE PEDAL TWICE TO RELIEVE THE VACUUM RESERVE IN THE BRAKE BOOSTER AND THE PEDAL STIFFENED UP WITH NO VACUUM ASSIST. I IMMEDIATELY PULLED THE VACUUM LINE FROM THE BRAKE BOOSTER AND THERE WAS NO VACUUM AT THE BOOSTER WITH THE MOTOR RUNNING AND THUS NO VACUUM ASSIST. AFTER FLEXING AND TAPPING THE LINE IN THE CHECK VALVE AREA, THE CHECKBALL RELEASED WITH A CLICK AND VACUUM WAS RESTORED. THIS IS A VERY VERY SERIOUS DESIGN FLAW THAT IS OCCURRING ON MANY NISSAN/INFINITI CAR AT THIS VERY MOMENT, JUST DO AN INTERNET SEARCH ON "NISSAN BRAKE PROBLEM WHEN COLD". THIS PROBLEM IS PARTICULARLY DANGEROUS IN THAT IT OCCURS ON START-UP AFTER THE BRAKE PEDAL IS DEPRESSED SEVERAL TIMES(THE VACUUM RESERVE IS DEPLETED). THIS CONDITION IS LIKELY TO OCCUR AFTER MOVING INTO TRAFFIC. ALTHOUGH THE BRAKING SYSTEM CONTINUES TO WORK WITHOUT ASSIST, THE FORCE REQUIRED TO OVERCOME THE NO VACUUM ASSIST IS MORE THAN MANY FEMALE, OLDER OR TEENAGE DRIVERS CAN APPLY. THE CONDITION FEELS LIKE THERE ARE NO BRAKES EVEN THOUGH THE PEDAL DOES NOT GO TO THE FLOOR. SOMETHING NEEDS TO BE DONE (RECALL) IMMEDIATELY! I HAVE NOT REPLACED THE PART(RUBBER VACUUM HOSE WITH INTEGRAL CHECK VALVE) YET, BECAUSE I KNOW TO DEPRESS THE BRAKES AT STARTUP SEVERAL TIMES BEFORE I MOVE THE CAR. I DO HAVE THE PART AND WILL BE MORE THAN HAPPY TO VIDEO TAPE THE FAILURE ON THE NEXT COLD MORNING(BELOW32 DEGREES APPROX) OR I WILL SEND THE HOSE TO YOU FOR TESTING. IF I WERE THE ONLY PERSON WITH THIS PROBLEM, I WOULD CONSIDER THIS DISTURBING, BUT NOT A DESIGN PROBLEM. I ONLY FIGURED OUT WHAT THE REAL PROBLEM IS(CHECKVALVE) ON THE INTERNET. *TR

SINCE OCT 25 2006 I HAD TO REPLACE 2 SETS OF OXYGEN SENSORS AND A LR WHEEL/ABS SENSOR AT MY EXPENSE AND ALL BEFORE 49,000 MILES. I THINK A SENSOR PROBLEM EXISTS OR SOMEONE IS TAKING ADVANTAGE OF ME. *NM

AT 31,000 BRAKES PULSATED BUT DID STOP CAR BUT NOT AS QUICKLY AS BEFORE PULSATING. I DID NOT EXPERIENCE ANY CLOSE CALLS SINCE I DRIVE SLOWLY AND BROUGHT CAR TO DEALER FOR REPAIR AT MY EXPENSE.. THE DEALER MACHINED FRONT ROTORS AND REPLACED PADS DUE TO ROTORS BEING WARPED. *NM

I OWN A 2001 INFINITI I30. I HAVE A RECURRENT PROBLEM WITH THE BRAKES ON THIS CAR. THE CAR SHAKES SO MUCH WHEN I'M BRAKING DRIVING AT AROUND 65 MPH. IT MAKES ME VERY NERVOUS BECAUSE I HAVE A TWO-YEAR-OLD CHILD IN THE BACK SEAT. I HAVE TAKEN IT BACK TO THE DEALER THREE TIMES. THE FIRST TIME WAS WHEN THE CAR WAS ONLY ABOUT A COUPLE YEARS OLD. THE FIRST TWO TIMES, THEY FIXED THE PROBLEM WITH THE ROTOR AND THE BRAKES FOR ME WITHOUT CHARGE. THE SERVICE PERSON AGREED THAT THIS IS A RECURRING PROBLEM WITH THIS MODEL. THE THIRD TIME I TOOK MY CAR BACK, THEY REFUSED TO FIX IT WITHOUT CHARGING ME. AND THE NEW SERVICE PERSONNEL THAT WAS THERE DENIED THAT THERE IS ANYTHING WRONG WITH THE BRAKING/ROTOR SYSTEM OF THIS MODEL. I HAVE RESEARCHED A LITTLE BIT MORE, AND HAVE FOUND THAT OTHER CAR OWNERS HAVE ALSO HAD SIMILAR PROBLEMS WITH THIS MODEL. I'M NOT SURE WHAT TO DO AT THIS POINT TO GET THIS PROBLEM FIXED. IF I HAVE TO PAY TO FIX THE ROTOR/BRAKES PROBLEM EVERY YEAR, THEN THAT WOULD BE VERY EXPENSIVE. I HAVE OWNED OTHER CARS BEFORE, AND I NEVER HAVE SO MUCH PROBLEMS WITH THE BRAKES SO OFTEN, ESPECIALLY IN A RELATIVELY NEW CAR. *JB
