THERE WAS NO CRASH OR RESULTING INJURIES--BUT HAVING A CLUTCH WHICH STICKS MAY EVENTUALLY LEAD TO A CATASTROPHIC INCIDENT. THE DEALERSHIP ADDRESSED THE PROBLEM AT 50,000 MILES, BUT IT HAS SINCE RETURNED. THERE ARE MANY G35-DEVOTED WEBSITES AND BLOGS WHERE G35 OWNERS COMPLAIN ABOUT THE SAME PROBLEM, BUT IT DOES NOT APPEAR THEY HAVE FOLLOWED UP BY FILING A COMPLAINT. MANY OWNERS REPORT THE SAME STICKY CLUTCH PROBLEM AT VARIOUS SPEEDS. FOR ME, IT'S HAPPENING AT ANY SPEED WHETHER IT IS SLOW OR FAST. INFINITI CLAIMS THIS REQUIRES A NEW CLUTCH--GIVEN THAT THE OWNERS HAVE HAD THEIR PROBLEMS AT VARIOUS POINTS OF MILEAGE, I AM NOT CONVINCED THIS IS RELATED TO THE CLUTCH ITSELF. THANKS VERY MUCH. *TR

HEAVY VIBRATIONS FROM THE TRANSMISSION/MOTOR WHEN STOPPED AND IN NEUTRAL W/O THE AIR ON. FEELS AS IF THE VEHICLE WANTS TO STALL WHEN IT VIBRATES. VIBRATIONS GET WORSE WHEN DRIVEN AT HIGH RPM'S. INFINITI DEALER TECH ADVISES THAT IT'S A TRANSMISSION PROBLEM BUT INFINITI'S CORPORATE OFFICE CLAIMS ITS NORMAL. *NM

SEVERAL TIMES WHEN DRIVING MY 2004 INFINITI G35X, THE CAR WILL ACCELERATE WHEN I DOWNSHIFT IN THE "TIPTRONIC" MODE FROM 3RD TO 2ND OR FROM 2ND TO 1ST. ALTHOUGH THIS HAS NOT CAUSED AN ACCIDENT, I WANTED TO PROVIDE THIS INFORMATION TO YOU AS I AM NOT SURE IF THIS IS THE WAY THE CAR IS INTENDED TO OPERATE. THIS CONDITION WOULD POTENTIALLY CAUSE AN ACCIDENT AT AN LOW SPEED (30 MILES PER HOUR OR LESS) WHERE THE DRIVER WAS NOT EXPECTING THE CAR WOULD "LUNGE" FORWARD WHEN DOWNSHIFTING WITH A TIPTRONIC TRANSMISSION

THIS COMPLAINT IS IN REGARDS TO THE 6 SPEED MANUAL TRANSMISSION. I HAVE HAD THE CAR SEVERAL MONTHS AND HAVE NOTICED A RATTLE/GRINDING NOISE EMINATING FROM THE TRANSMISSION WHILE THE CAR IS STOPPED AND IDLING. THE CAR MUST BE WARMED UP AND HAVE BEEN DRIVEN IN STOP AND GO TRAFFIC FOR APPROXIMATELY 15 MINUTES IN ORDER TO HEAR THE NOISE. WHEN I DEPRESS THE CLUTCH PEDAL, THE NOISE STOPS. I UNDERSTAND THIS IS AN ISSUE WITH THE "THROW OUT" BEARING IN THE MANUAL TRANSMISSION THAT HAS APPARENTLY BEEN RESOLVED IN THE 2005 MODEL. IN ADDITION TO THE NOISE WHILE IDLING, I HAVE NOTICED A "CLUNK" SOUND WHEN SHIFTING INTO AND OUT OF FIRST GEAR. THE NOISE IS GETTING WORSE, BUT IS CURRENTLY TOLLERABLE. THE NOISE WHILE IDLING IS NOT TOLLERABLE.*AK

TRANSMISSION MAKES CHATTERING NOISE AS THE ENGINE SHUTS DOWN (ONLY ABLE TO HEAR WHEN THE TRANSMISSION IS WARMED UP AND ONLY ABLE TO HEAR IT FROM OUTSIDE OR WITH THE DOOR OPEN.). TRANSMISSION WAS REPLACED BUT THE CHATTERING NOISE STILL EXISTS. I WAS TOLD THAT THE PROBLEM EXISTS INTERNALLY IN ALL 6 SPEED TRANNYS' AND THE PROBLEM CAN NOT BE ATTENDED TO UNLESS MORE PEOPLE COMPLAIN. *JB

2004 WITH APPROX. 7,200 MILES. RATTLING NOISE HEARD IN 1ST AND 2ND GEAR. DEALER SAID IT NEEDED NEW TRANNY. REPLACED TRANNY. PICKED UP CAR AND WHILE DRIVING HOME, COULD NOT GET IT INTO 5TH OR 6TH GEAR. BACK TO DEALER. WAS TOLD THAT TRANNY WAS BAD AND HAD TO BE REPLACED AGAIN. PICKED UP CAR AND WITHIN A WEEK HEARD A KNOCKING NOISE IN 5TH GEAR, VIBRATION IN STICK SHIFT AND A CLANKING NOISE WHEN APPLYING THE BRAKES FOR THE FIRST TIME AFTER CAR SITTING FOR A BIT. LATER FOUND OUT THAT DEALER LIED ABOUT INSTALLING THE 2ND TRANSMISSION. DEALER REFUSES TO TELL ME OR GIVE ME PAPER WORK STATING WHAT WAS DONE ON CAR THE 2ND TIME THEY HAD. INFINITI CONSUMER AFFAIRS AND REGIONAL MANAGER HAVE NOT PROVEN TO BE OUT FOR CONSUMERS INTEREST. IN FACT, THEY CALL LYING ABOUT THE 2ND TRANNY A "MISTAKE". SOUNDS LIKE FRAUD TO ME, ESPECIALLY WHEN I WAS TOLD SEVERAL TIMES THAT THEY DON'T REPAIR TRANNYS ...THEY ONLY REPLACE THEM. THEY ALSO GAVE ME A WORK ORDER/PAPERWORK STATING THAT NEW TRANNY WAS INSTALLED TWICE. *JB
