2011 Infiniti G37

ECT: AUTOMATIC TRANSMISSION CONTROL LOGIC / ADAPTIVE SHIFT PATTERN: THE VEHICLE DOES NOT PRODUCE CONSISTENT AND RELIABLE RESPONSE TO THROTTLE COMMAND WHEN ACCELERATING INTO AND AROUND TRAFFIC. ON SEVERAL INSTANCES, WHEN PULLING OUT OF A DRIVEWAY INTO ONCOMING ARTERIAL TRAFFIC, THERE HAS BEEN NO RESPONSE TO THROTTLE INPUT. A DELAY OF 2 ~ 4 SECONDS HAS OCCURRED AND CREATES AN EXTREMELY HAZARDOUS SITUATION. THIS FAULT HAS ALSO OCCURRED AT FREEWAY SPEEDS WHEN ATTEMPTING TO PASS FROM SPEEDS BETWEEN 40 & 75 MPH! THIS BEHAVIOR WAS NOT OCCUR INITIALLY, UNTIL THE CAR HAD ABOUT 3,000 MILES. I HAVE CONTACTED INFINITI USA, AND KEPT AN APPOINTMENT WITH A REGIONAL CUSTOMER SERVICE REP. ALONG WITH A DEALER SERVICE MANAGER IN TACOMA, WA LAST DECEMBER. THE OUTCOME OF THIS DIALOG WAS THAT THE VEHICLE DID NOT EXHIBIT THE "FAULT" ON THAT TEST DRIVE, THE MANUFACTURER IS AWARE OF "SOME CUSTOMER CONCERNS REGARDING THE 7-SPEED AT BEHAVIOR", AND THAT THERE IS NO SERVICE BULLETIN AS-YET TO RESOLVE SUCH A FAULT. THE REGIONAL REP. DID SUGGEST THAT (UN-OFFICIALLY), THERE IS AN EFFORT SEEKING TO RELEASE A SERVICE BULLETIN UPDATE IN THE FORM OF A PCM / TCM FLASH OF ROM DATA (MAPPING) TO RESOLVE THE ONGOING COMPLAINTS OF UN-RELIABLE TRANSMISSION & POWER TRAIN RESPONSE BEHAVIORS. THERE HAVE ALREADY BEEN 2 SUCH SERVICE BULLETINS TO RESOLVE OTHER MINOR ANNOYANCE BEHAVIORS REGARDING SHIFT QUALITY, BUT NOT FOR THIS GROSS LACK OF COMMAND / CONTROL. I HAVE NOT HEARD BACK FROM INFINITI USA / 3 MONTHS. I BELIEVE THIS IS A SERIOUS SAFETY HAZARD AND WOULD LIKE THE US-DOT / NHTSA TO PURSUE THIS ISSUE WITH NISSAN MOTORS CORP. / INFINITI USA TO MANDATE AN EFFECTIVE RESOLUTION. *TR

2011 INFINITI G37X SIDE MIRRORS BECOME VERY DISTORTED IN COLD WEATHER. THE DEALER AND INFINITI ATTEMPTED TO FIX THE PROBLEM 3 TIMES, WITH NO SUCCESS. AFTER THE 3RD TIME, BOTH THE DEALER AND INFINITI'S CORPORATE OFFICE HAVE STATED THIS PROBLEM APPEARS TO EXIST ON ALL INFINITI'S IN THIS MODEL YEAR, AND THERE IS NOTHING THEY CAN DO ABOUT IT. THE DISTORTION CAUSES OBJECTS IN SIDE MIRROR TO BECOME WAVY, HINDERS DEPTH PERCEPTION, AND CAUSES CONFUSION. *TR

TL* THE CONTACT OWNS A 2011 INFINITI G37SX COUPE. WHILE DRIVING APPROXIMATELY 20 MPH, THE CONTACT APPROACHED A STOP SIGNAL, ENGAGED THE BRAKE PEDAL AND THE VEHICLE SURGED FORWARD WITH AN INCREASE IN THE RPMS. THE IDENTICAL FAILURE OCCURRED FIVE TIMES. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER ON SIX OCCASIONS REGARDING THE UNINTENDED ACCELERATION. THE TECHNICIAN WAS UNABLE TO DUPLICATE THE FAILURE OR DETECT A TROUBLE CODE DURING THE DIAGNOSTIC TEST; HOWEVER, THE ELECTRONIC MODULE WAS REPROGRAMMED. THE FAILURE CONTINUED TO OCCUR. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 1,000.

AS I WAS WAITING TO CROSS A MAJOR HIGHWAY JUNCTION IN UPPER MARLBORO, MD, I ALMOST HAD A COLLISION AFTER CROSSING THE HIGHWAY DUE TO WHAT I SUSPECT A FAULTY TRANSMISSION WITH HESITATION IN SHIFTING. THERE WAS A SUV WAITING TO TURN AND WHILE I HAD THE RIGHT OF WAY, THEY PULLED OFF AND AS MY CHANCE TO CROSS THE 2 LANE HIGHWAY, THEY DID TOO. I PUNCHED THE GAS AND IN THE MIDDLE OF THE ROAD, THE ENGINE TOOK A FEW SECONDS TO GET INTO GEAR SO I LITERALLY WAS IN THE ROAD OF ONCOMING TRAFFIC THAT WAS DRIVING AT SPEEDS IN EXCESS OF 55+ MPH. IT HAPPENED WITHIN 5 SECONDS BUT AFTER I CROSSED AVOIDING A FRONT AND SIDE COLLISION, I PULLED OFF THE ROAD BECAUSE I WAS SHAKING. OTHER INSTANCES WHILE DRIVING AT HIGHWAY SPEEDS THAT I PULL INTO THE LEFT HAND LANE TO PASS A CAR IN FRONT OF ME AND THE ENGINE IS SLOW TO RESPOND AS IT ACCELERATES FROM A LOW GEAR RESULTING IN A LAGGING SOUND/ READING OF THE TACH JUMPING AROUND AS I'M NEARLY HIT FROM BEHIND BECAUSE THE CARS HESITATION IN ACCELERATING. I'M ALSO HEARING THE ENGINE REV UP WITH NO TAKE OFF, SHIFTING IN DRIVE SPORT (DS) MODE IS NOT RESPONSIVE AND EVEN USING THE PADDLE SHIFTERS ISN'T ANY BETTER. I FEEL THIS CAR IS GOING TO BE A DETRIMENT IF INFINITI DOESN'T ADDRESS THE PROBLEM WITH THE 7 SPEED AT. IT HAPPENS UNDER LIGHT ACCELERATION ON THE 3-4 OR/AND 5-6 UPSHIFT. I EVEN SMELLED THE ENGINE AFTER I GOT OUT OF THE CAR AFTER DRIVING TO THE STORE THAT WAS IN MEDIUM/ LIGHT TRAFFIC ABOUT 20 MINUTES. *TR

AFTER LESS THAN 3700 MILES THE CONVERTIBLE TO HAS BEEN DENTED BY THE RETRACTING MECHANISM. THE DEALER INDICATES IT IS DUE TO STOPPING THE RETRACTION AND LIFTING OF THE TOP BY THE HYDRAULIC SYSTEM. IT IS NOT COVERED UNDER WARRANTY. THE PURPOSE OF THE HYDRAULIC LIFT AND RETRACT SYSTEM IS JUST THAT, TO LIFT AND RETRACT! HOW CAN NORMAL OPERATION CREATE DAMAGE TO THE VEHICLE? *KB

TL* THE CONTACT OWNS A 2011 INFINITI G37 COUPE. THE CONTACT STATED THAT AT 2 MPH, HE WAS ATTEMPTING TO PARK THE VEHICLE IN A RESIDENTIAL GARAGE WHEN THE VEHICLE ABNORMALLY ACCELERATED AND CRASHED. THE FRONT BUMPER WAS SLIGHTLY DAMAGED BUT THE CONTACT WAS NOT INJURED. THE VEHICLE WAS TAKEN TO THE DEALER WHO CONTACTED THE MANUFACTURER AND A REPRESENTATIVE WAS SENT TO INSPECT THE VEHICLE. THERE WERE NO FAILURES FOUND WITHIN THE VEHICLE. THE CONTACT STATED THAT HE HAD EXPERIENCED THE FAILURE TWICE PRIOR TO THE CRASH. THE DEALER ALSO INSPECTED THE VEHICLE BUT COULD FIND NO FAILURES. THE FAILURE MILEAGE WAS 750.

I PURCHASED A NEW INFINITI G37X SEDAN IN THE BEGINNING OF JULY 2011. EACH TIME I REFILL THE CAR AT GAS STATION, THE PUMP JUST STOPS FILLING AFTER ONLY A COUPLE OF SECONDS. EACH REFILL WAS DONE BY BYPASS THE PRESSURE SENSOR BUILT IN THE PUMP AND BY GUESSING HOW MANY GALLON CAN BE FILLED IN THE TANK, BLINDLY, EVEN THOUGH IT DOESN'T LIKE A LIFE THREAT ISSUE, IF THE FUEL DID OVERFLOW, IT WOULD RESULT IN A GAS STATION IN FIRE. *TR

I PURCHASED A NEW 2011 INFINITI G37X FROM SALERNO DUANE RT 10 DENVILLE NJ. ABOUT 1 MONTH INTO OWNERSHIP OF THE CAR I HAD THE CAR PARKED IN MY DRIVEWAY RUNNING WHILE I WALKED TO THE END OF THE DRIVEWAY TO PICK UP GARBAGE CANS. I HEARD A CRASH , I FOUND THE CAR CRASHED INTO MY GARAGE DOING DAMAGE TO THE CAR , MY GARAGE WALL AND MY SON'S BIKE. THE CAR WAS STILL IN PARK WHEN I FOUND IT . I FEEL THERE IS A SOMETHING WRONG WITH THE CAR MY DRIVEWAY IS FLAT AND I WANT TO KNOW WHY THIS HAPPENED. I WANT THE CAR REPAIRED OR REPLACED. *TR
