2007 Infiniti G35 Powertrain & Transmission Problems

powertrain control module my car keeps dying out at stop lights and on freeway Yes by a service center Auto care Precision Tune Autocare just dying out on freeway when have to stop and go on freeway. It started doing this about 4 weeks ago as of today. 6/7/2021

TWO DIFFERENT INCIDENTS - I WAS IN TWO MINOR LOW SPEED INCIDENTS. I BELIEVE AT THE TIME OF THE SECOND THE BRAKE ROD GOT BENT (WHICH IS CURRENTLY SPECULATION AND THE INSURANCE IS INVESTIGATING) FROM THE FIRST ACCIDENT. AFTER THE FIRST MY ACCELERATOR WOULD NOT FUNCTION ON SOME LEFT HAND TURNS. I GOT IN THE SECOND ACCIDENT BECAUSE OF THE INABILITY TO "BRAKE HARDER" AND I WAS AMAZED I COULDN'T STOP IN THE DISTANCE PROVIDED, AND THIS BRAKING SCENARIO AND OUTCOME IS REPEATABLE. IF I BRAKE HARD -- HARDER -- FULL STOP. BY THE TIME I DO A FULL STOP MY BRAKING POWER IS DIMINISHED AND IN MY ACCIDENT I WAS UNABLE TO STOP IN A "NORMAL" DISTANCE. FURTHERMORE, AFTER THIS SECOND ACCIDENT AT < 20 MPH. I HAVE INTERMITTENT ACCELERATOR FAILURE IN ALL DRIVING SCENARIOS. I COULD BE DRIVING AND IT JUST CUTS OUT. NO ERROR LIGHTS IN EITHER OF THESE SCENARIOS. NO CHECK ENGINE, NO SLIP, NO ABS, WARNINGS. I PREVIOUSLY TRIED TO BRING IT UP TO CORPORATE NISSAN AND THEY SAID I HAD TO CONTACT THE LOCAL DEALERSHIP. BOTH DEALERSHIPS I TRIED PAWNED ME OFF TO PARTS DEPARTMENT, WHICH THE GUY WAS CONFUSED AS TO WHY I AM ASKING HIM ABOUT POTENTIAL SHORT FALLS. THEY WANTED OVER $1,000 EACH ISSUE TO INVESTIGATE. MEANWHILE AS I NOW FIND MY CAR UNSAFE TO DRIVE FOR LACK OF ACCELERATING AND BRAKING ABILITIES, AND THE INSURANCE COMPANY IS INVESTIGATING. TWO ACCIDENTS IN 6 MONTHS, AND AT LEAST THE LATTER I THINK COULD BE DUE TO A POTENTIAL FAULTY PART - AS EVERY MECHANIC I HAVE REACHED OUT TO SAID IF IT IS THE BRAKE ROD, AND IN THE ACCIDENTS I HAD, IT SHOULD NOT HAVE BENT (IF THAT ENDS UP BEING THE ROOT CAUSE). LET ALONE THE ACCELERATOR ISSUES. *TR

THERE IS A HESITATION WHEN ACCELERATING FROM STOP AND THE VEHICLE IS WARMED AFTER ABOUT 10 MINUTES OF RUNNING. WHEN TACHOMETER HITS 1100 RPMS THE ENGINE SPUTTERS DOWN TO ABOUT 800 RPM AND JERKS FORWARD. THIS DOES NOT APPEAR TO BE A TRANSMISSION ISSUE AS THIS HAPPENS EVERY TIME WHETHER IN DRIVE, PARK OR NEUTRAL. VEHICLE HAS ONLY STALLED ONCE SO FAR. THERE APPEARS TO BE REPORTS OF THIS BEING RELATED TO A REAR TIMING BELT SHIELD GASKET. THIS IS VERY CONCERNING WITH THE VEHICLE STALLING. *TR

TL* THE CONTACT OWNS A 2007 INFINITI G35 SPORT. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE CLUTCH PEDAL FAILED TO OPERATE NORMALLY. THE CONTACT ALSO MENTIONED THAT HE HAD TO BURN THE CLUTCH AND GRIND THE GEARS IN ORDER TO MANEUVER THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO STATED THAT CLUTCH SLAVE CYLINDER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 93,000. UPDATED 11-25-13 *BF THE VEHICLE WAS REPAIRED. UPDATED 12/04/13

TL* THE CONTACT OWNS A 2007 INFINITI G35. WHILE DRIVING UPHILL AT AN UNKNOWN SPEED, THE CLUTCH PEDAL TRAVELED TO THE FLOORBOARD. IN ADDITION, THE BRAKE PEDAL REQUIRED EXCESSIVE FORCE. THE VEHICLE WAS TAKEN TO A DEALER WHO REPLACED THE CLUTCH SLAVE CYLINDER, BUT THE FAILURE RECURRED A YEAR AFTER THE REPAIR. ON A SECOND OCCASION, THE CLUTCH PEDAL WAS STUCK AND WAS PUMPED IN ORDER TO BE RELEASED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE CLUTCH SLAVE CYLINDER NEEDED TO BE REPLACED AGAIN. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

CAR WOULD DIE AFTER BEING STARTED. LAG TIME IN ACCELERATION. UPON INSPECTION WE WERE TOLD THE REAR TIMING COVER HAS A SEAL INSIDE OF IT THAT IS BROKEN. THE MECHANICS SHOWED US 4 VEHICLES IN THEIR SHOP WITH THE SAME ISSUE. THE SEAL INSIDE THIS COVER IS SO HARD TO REACH THE ENTIRE ENGINE MUST BE DROPPED IN ORDER TO FIX THIS. IT IS A $3K+ JOB. THE MECHANICS ADVISED THAT UNTIL NISSAN FIXES THE QUALITY OF THIS SEAL IT WILL BLOW AGAIN IN 80K. THE SEAL IS CREATING OIL LEAKS INTO MY ENGINE AND WILL EVENTUALLY LOCK UP THE TRANSMISSION. WE WERE ADVISE THERE MAY BE A SERVICE BULLETIN ON THIS ISSUE, AND A 100,000K EXTENSION ON THE POWERTRAIN IS IN THE WORKS. WE CANNOT CONFIRM THIS YET, AS WE ARE WAITING FOR INFINITI TO RESPOND. WE HAVE ALWAYS KEPT UP WITH THE SUGGESTED MAINTENANCE ON THIS VEHICLE WITH REGULAR OIL CHANGES. WE ARE EXTREMELY DISPLEASED WITH THE FACT THAT THIS IS AN ISSUE THAT INFINITI IS AWARE OF BUT HASN'T FIXED YET. WE CAN ALSO CONFIRM THAT THE PASSENGER SEAT (FRONT) SHOWS THAT I AM NOT SITTING IN THE CAR AND THE AIRBAGS TURNOFF. THIS FLUCTUATES GIVEN THE TEMP OUTSIDE. WE BELIEVE THIS MAY BE AN ELECTRICAL ISSUE. *TR

TL*THE CONTACT OWNS A 2007 INFINITI G35. WHILE DRIVING APPROXIMATELY 35 MPH IN DAMP WEATHER, THE VEHICLE BEGAN MAKING A NOISE WHICH APPEARED TO BE COMING FROM THE ENGINE COMPARTMENT. THE CONTACT CONTINUED DRIVING 20 MILES AND THE NOISE CONTINUED. HE STATED THAT HE HAD TO DRIVE SLOWER BECAUSE WHEN HE ATTEMPTED TO SHIFT, THE VEHICLE WOULD LUNGE FORWARD. HE CALLED THE MANUFACTURER AND THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER. THE DEALER WAS UNABLE TO FIND A PROBLEM RELATED TO THE NOISE BUT INFORMED THE CONTACT THAT THE BATTERY NEEDED TO BE REPLACED. THE BATTERY WAS REPLACED; HOWEVER, THE FOLLOWING DAY, THE CONTACT HEARD THE NOISE AGAIN. HE CALLED THE MANUFACTURER AGAIN WHO REFERRED HIM TO AN AUTHORIZED DEALER. THE DEALER TOLD HIM THAT THE TRANSMISSION NEEDED TO BE REPLACED; THE TRANSMISSION WAS ALSO REPLACED. HE WANTED TO EXCHANGE THE VEHICLE FOR A DIFFERENT ONE BUT THE MANUFACTURER REFUSED. THE FAILURE MILEAGE WAS APPROXIMATELY 36,000. THE CURRENT MILEAGE WAS APPROXIMATELY 38,000.

WHEN DRIVING MY G35 COUPE IN STOP & GO TRAFFIC IN WARM WEATHER, THE CLUTCH DOES NOT COMPLETELY ENGAGE. THE PEDAL ONLY COMES ABOUT HALF-WAY UP AND SOMETIMES LESS THAN THAT. I ALMOST HAD TO PUT THE CAR OF THE SIDE OF THE ROAD BECAUSE THE CLUTCH WOULD NOT ENGAGE AT ONE POINT. I HAVE REPLACED THE FLUID AND ENSURED THE LINES WERE CLEAR OF AIR TO NO RESOLVE. THE CAR HAS LESS THAN 20K MILES. *TR

THE 2007 INFINITI G35 SEDAN MANUAL TRANSMISSION'S CLUTCH HAS BEEN KNOWN TO STICK TO THE FLOOR, THUS STRANDING IT'S DRIVER. THIS IS A PROBLEM WITH EITHER THE MASTER OR SLAVE CLUTCH CYLINDER. THIS IS RANDOM AND DOES NOT MATTER HOW THE CAR IS BEING DRIVEN. I FEEL THIS IS A SAFETY ISSUE WHICH SHOULD BE ADDRESSED BY INFINITI. I PERSONALLY KNOW SEVERAL PEOPLE WHO WORK FOR INFINITI, AND THEY HAVE RECOGNIZED THIS AS A COMMON PROBLEM. I FEEL A TECHNICAL SERVICE BULLETIN IS NECESSARY TO ADDRESS THIS ISSUE. *TR

USUALLY AFTER THE CAR HAS NOT BEEN DRIVEN FOR A FEW DAYS, I WILL GET IN AND PRESS THE CLUTCH AND IT WILL SINK TO THE GROUND (I.E. THERE IS NO PRESSURE IN THE CLUTCH LINE). AFTER PUMPING IT A FEW TIMES, IT WILL USUALLY REBUILD PRESSURE AND BE DRIVABLE. I HAVE REQUESTED THAT MY DEALERSHIP FIX THE PROBLEM, BUT THEY CLAIM TO BE UNABLE TO DIAGNOSE IT, REGARDLESS OF MY EXPLANATION. THEY HAVE BLED THE CLUTCH LINE AT ONE POINT, TEMPORARILY FIXING THE PROBLEM, BUT IT IS NOT A SUSTAINED SOLUTION. *TR

PURCHASED A NEW 2007 INFINITI G35, VEHICLE HAS UNDER 10000 MILES AND HAS HAD ISSUE ON AT LEAST 6 OCCASIONS. THE CLUTCH PEDAL HAS ONLY PARTIALLY DISENGAGED WHILE SHIFTING. SLOWING THE VEHICLE AND PUMPING THE CLUTCH WILL RELEASE IT. THE SMELL OF CLUTCH IS PRESENT FOLLOWING THE EVENT. INFINITI COULD NOT DUPLICATE THE PROBLEM SO NO WORK WAS DONE ON MY CAR. IT STILL HAPPENS. ALSO OCCURED ON THE HIGHWAY, LOSS OF POWER ETC. SAFETY CONCERN! *CN

I HAVE HAD MANY PROBLEMS WITH MY G35X MOST NOTABLY THE CAR JERKS VIOLENTLY AT OR AROUND 38 MPH, I HAVE CALLED CONSUMER AFFAIRS AND THE DEALER AND THEY BOTH DENY THERE EVEN BEING A PROBLEM. THE COLOR IS LIQUID PLATINUM AND THERE SEEMS TO BE METAL FLAKES IN THE CLEAR CAUSING THERE TO BE THOUSANDS OF TINY RUST SPOTS ON THE PAINT. *TR
