2003 Infiniti G35 Speed Control & Cruise Problems

WAS DRIVING MY INFINITI G35 2003, WHILE PASSING A VEHICLE GOING SLOW MY ACCELERATOR WENT TO THE FLOOR, BEYOND MY CONTROL, I HIT THE GAS PEDAL HARD WITH MY RIGHT FOOT WHILE PANICKING TRYING TO RELEASE IT. I WAS COMING TO AN INTERSECTION I HAD TO STAND ON MY BRAKE PEDAL. I DON'T KNOW HOW FAST EXACTLY BUT IT WAS OVER 100 MPH. IT HAPPENED VERY FAST, I DID TRY TO PUT IT IN NEUTRAL BUT MISSED AND HIT REVERSE I THEN WENT SIDEWAYS AND MY CAR MADE SOME VERY WEIRD WHINING SOUNDS. I THEN SHUT OFF THE IGNITION. I SHOULD'VE DONE THAT FIRST BUT IN THAT SITUATION YOU JUST PANIC. AFTER COASTING TO A LONG STOP I STARTED IT AGAIN. SAME THING STILL 8K RPMS, PEDAL STILL AT THE FLOOR, I SHUT IT OFF AND INSPECTED MY PEDAL IT WAS STUCK TO THE FLOOR. NO FLOOR MAT GRABBED IT (LIKE INFINITY INSISTED HAPPENED) AND I AM 150 PERCENT SURE I DID NOT DEPRESS MY PEDAL THEN OR EVER TO THE FLOOR FOR WHICH IT COULD STICK. *TR

I WAS DRIVING MY SISTER-IN-LAW TO MACARTHUR AIRPORT IN ISLIP, NY. WE CAME TO A RED LIGHT JUST OUTSIDE THE AIRPORT. I TOOK MY FOOT OFF THE GAS PEDAL AND PUT IT ON THE BRAKE PEDAL, BUT I FELT THE CAR WAS STILL TRYING TO MOVE AS THOUGH THERE WAS ANOTHER FOOT ON THE GAS PEDAL. FORTUNATELY IT WAS NOT THAT MUCH THRUST INVOLVED. I KEPT PRESSING HARDER ON THE BRAKE, BUT THE CAR KEPT INCHING FORWARD AT ABOUT 2 MPH. I WASN'T SURE IF I COULD STOP BEFORE HITTING THE CAR IN FRONT OF ME (FORTUNATELY I ALWAYS LEAVE LOTS OF ROOM). SO I PUT THE CAR IN NEUTRAL. BECAUSE MY FOOT WAS PRESSED VERY HARD ON THE BRAKE, THERE WAS A SUDDEN JERK AS WE STOPPED SUDDENLY. LUCKILY WE ALL HAD OUR SEAT BELTS ON. IT HAS NOT HAPPENED SINCE. I DON'T THINK THERE IS ANYTHING WRONG WITH THE PEDAL. MAYBE THERE WAS SOME TYPE OF ELECTRICAL INTERFERENCE FROM THE AIRPORT THAT MESSED WITH MY CAR'S ELECTRONICS? *TR

2003 INIFINITI G35 SEDAN LURCHES FORWARD WHEN CAR IS STOPPED. THE CAR ACCELERATES UNTIL BRAKES ARE SEVERELY DEPRESSED. THIS HAS OCCURRED AT STOP SIGNS, STOP LIGHTS AND IN MY GARAGE. THIS PROBLEM IS A DANGEROUS ISSUE. MY CAR HAS BEEN DAMAGED DUE TO THIS ISSUE. *TR

TL* THE CONTACT OWNS A 2003 INFINITI G35. WHILE APPROACHING AN INTERSECTION AT SPEEDS OF 55 MPH AND DEPRESSING THE BRAKE PEDAL, THE VEHICLE BEGAN TO ABNORMALLY ACCELERATE. SHE ATTEMPTED TO APPLY PRESSURE TO THE BRAKE PEDAL TO NO AVAIL. A PEDESTRIAN WAS IN HER PATH WHEN SHE FORCED THE VEHICLE INTO THE PARK POSITION TO AVOID HITTING HIM. IMMEDIATELY, THERE WAS A SUDDEN AND ABNORMAL INCREASE IN THE ENGINE RPMS ACCOMPANIED BY A LOUD NOISE. SHE SHUT THE ENGINE OFF AND RESTARTED THE VEHICLE AND WITHIN A FEW MOMENTS, THE VEHICLE WAS FUNCTIONING NORMALLY. THE DEALER COULD NOT DUPLICATE THE FAILURE. NO REPAIRS WERE MADE. THE MANUFACTURER WOULD NOT OFFER ANY ASSISTANCE. THE FAILURE MILEAGE WAS 35,000 AND THE CURRENT MILEAGE WAS 78,000.

I HAVE A 2003 G35 SEDAN WITH APPROXIMATELY 13,000 MILES ON IT. WHILE TRAVELING DOWN A SIDESTREET AT 35 MPH APPROACHING A STOP SIGN AT A MAJOR FOUR LANE CROSS STREET, REMOVED FOOT FROM ACCELERATOR PEDAL TO BEGIN SLOWING DOWN THE VEHICLE WHEN THE CAR SPONTANEOUSLY REVVED AT HIGH RPM (OVER 6000 RPM). HAD TO APPLY THE BRAKE FORCEFULLY TO ATTEMPT TO STOP THE VEHICLE AND THE CAR POWERED THROUGH THE STOP SIGN AND INTO THE FIRST CROSS LANE OF THE FOUR LANE STREET. A CAR ON THE CROSS STREET HAD TO SWERVE TO AVOID STRIKING OUR VEHICLE. THE CAR COULD ONLY BE STOPPED BY THROWING THE SHIFT LEVER INTO NEUTRAL. ON TWO PREVIOUS OCCASIONS WHEN THE VEHICLE WAS ABOUT ONE MONTH OLD, EXPERIENCED A SUDDEN SPONTANEOUS REVVING OF THE ENGINE WHILE STOPPED AT A SIGNAL. THE TWO PREVIOUS OCCURRENCES DID NOT RESULT IN LOSS OF CONTROL OF THE VEHICLE. ON THE MOST RECENT OCCURRENCE, I HAD THE VEHICLE TOWED TO OUR SERVICING DEALER (AUTOPLACE INFINITI), WHERE THEY CLAIMED TO HAVE CONDUCTED A THOROUGH DIAGNOSTIC. THEY REPORTED THAT THEY WERE UNABLE TO FIND ANY DEFECTS, COMPUTER ERROR CODES OR MANUFACTURER SERVICE BULLETINS ON THIS PROBLEM, AND, OF COURSE, WERE UNABLE TO DUPLICATE THE PROBLEM. I HAVE WRITTEN TO INFINITI CONSUMER AFFAIRS ABOUT THE PROBLEM AS WE ARE TERRIFIED TO DRIVE THE VEHICLE AND IT HAS BEEN IDLE IN OUR GARAGE THE PAST THREE WEEKS AWAITING A RESPONSE FROM INFINITI AS TO THIS SERIOUS PROBLEM. *NM

2003 INFINITI G35 WAS TURNING INTO PARKING STALL AT ABOUT 5 MPH WHEN THE CAR SUDDENLY ACCELERATED WITHOUT THE ACCELERATOR PEDAL TOUCHED. BRAKES WERE NOT USED WITH SUFFICIENT FORCE TO STOP THE CAR. CAR JUMPED CURB, TRAVELED FIFTY FEET AND HIT A TREE.*AK

VEHICLE HAD ISSUES WITH NOT WANTING TO ACCELERATE FASTER THAN 5 MPH. TOWED VEHICLE TO DEALERSHIP, THEY STATED IT WAS A PINCHED CRUISE CONTROL GROUND WIRE AND FIXED IT UNDER WARRANTY. VEHICLE OPERATED FINE FOR ONE WEEK, HAD THE SAME PROBLEM. TOWED VEHICLE BACK TO DEALERSHIP. THIS TIME WAS TOLD THAT THE ECU AND WIRING HARNESS NEEDED TO BE REPLACED DUE TO IT GETTING WET FROM A GROMMET THAT WAS LOOSE DUE TO A AFTERMARKET ELECTRONICS WIRE UNDER IT. NOT COVERED UNDER WARRANTY. HAVE NOT HAD VEHICLE FOR ~5 WEEKS AND NO LOANER CAR WAS PROVIDED. UPON QUESTIONING INFINITI ABOUT WHY THE DELAY, I WAS TOLD THAT APPARENTLY THEY NEEDED TO REPLACE THE WIRING HARNESS AND NONE WERE AVAILABLE. THIS IS BECAUSE APPARENTLY THE 2003.5 G35 COUPE HAS A DIFFERENT HARNESS THAN THE 04 G35 COUPE. WAS TOLD JAPAN HAD TO SPECIALLY MAKE A HARNESS AND SHIP IT. WILL NOT GET HARNESS TILL THE 20TH OF MARCH. PROBLEM WAS THAT DEALERSHIP SHOULD HAVE CAUGHT THE PROBLEM WITH THE FIRST TRIP THERE. HAD THAT BEEN CAUGHT I WOULD NOT BE PAYING ~3000.00 AND WITH OUT A CAR FOR 5 WEEKS. UPON TRYING TO DISCUSS OPTIONS WITH SERVICE MANAGER I WAS TOLD THAT THEY WOULD GO TO COURT, AND THAT THEY WOULD WIN BECAUSE THEY HAVE MORE MONEY THAN I DO. *AK

2003 INFINITI G35 WITH ACCELERATION ISSUES. CUSTOMER STATES THAT THE CAR LUNGED FORWARD WHILE SHE WAS STOPPED AT A RED LIGHT. SHE SAYS THIS HAS HAPPENED FOUR TIMES. SHE SAYS SHE HAS HAD TO TURN THE WHEEL TO AVOID HITTING OTHER VEHICLES. *KB

WHEN VEHICLE IS AT A COMPLETE STOP WITH FEET DEPRESSED ON THE BRAKE PEDAL, AND AIR CONDITIONER IS ON, VEHICLE WILL SUDDENLY ACCELERATE. BRAKE PEDAL HAS TO BE DEPRESSED VERY HARD TO STOP VEHICLE. CAUSE OF SUDDEN ACCELERATION IS UNDETERMINED.*AK
