2009 Infiniti G37

PULLING INTO PARKING STALL (BRAKES APPLIED / TRAVELING 5-10 MPH) THE CAR LURCHED FORWARD TWICE AND STUCK A PARKED FULL SIZE TRUCK. THE CAR BOUNCED BACKWARDS AND LURCHED FORWARD AGAIN AND STUCK THE TRUCK A SECOND TIME AND BOUNCED BACKWARDS AGAIN. THE ( OFF BUTTON) WAS ABLE TO BE PUSHED AT THAT TIME. THE BRAKE WAS FULLY APPLIED THE ENTIRE TIME. THIS HAS BEEN THE ONLY OCCURRENCE. INFINITY HAS NOT BEEN ABLE TO DUPLICATE PROBLEM AND HAS DOWNLOADED THE DATA BASE. THE FORMAL REPORT WILL TAKE APPROX. 4 WEEKS TO COMPLETE. NO PARTS HAVE BEEN REPLACED. INFINITIES CONSUMER'S AFFAIR HAS TOLD US TO PICKUP THE VEHICLE AND DRIVE THE VEHICLE DESPITE NO EXPLANATION OR WRITTEN PROOF THE VEHICLE IS SAFE TO DRIVE. THE PROBLEM IS RELATED TO EITHER BRAKING, ACCELERATION OR BOTH. *TR

MY 2009 INFINITI GX 37X LOST POWER WITHOUT WARNING. THE MPH WENT FROM 50 DOWN TO 30 IN SECONDS, THE RPMS WOULD NOT GO ABOVE 1500. ACCELERATION FAILED. POWER STEERING AND BRAKING STILL WORKED. I HAD TO PULL OVER AND RESTART THE ENGINE. THE FIRST TIME THIS HAPPENED WAS JULY 2009 AND THE DEALERSHIP SAID NOT TO WORRY, THAT IT WAS PROBABLY AN ISOLATED INCIDENT AND TO BRING IT IN IF IT HAPPENED AGAIN. IF SOMETHING HAPPENS ONCE, I CAN REASON IT AWAY. BUT, TWICE? THIS IS A MAJOR SAFETY ISSUE AND INFINITI NEEDS TO ISSUE A RECALL ASAP. DRIVING CONDITIONS HAVE NO FACTOR AND THIS PROBLEM STRIPS THE DRIVER OF ANY CONTROL OF THE VEHICLE. THE DEALERSHIP DID A "REFLASH" OR ECU UPDATE AND SAID THAT A SIMILAR PROBLEM OCCURED ON A "M" MODEL. I AM NOT CONVINCED THIS HAS SOLVED THE PROBLEM. I AM TERRIFIED OF DRIVING THIS CAR. *TR

APPARENTLY ON 2009 INFINITI G37S, THERE IS A PROGRAMMING ERROR/DEFICIENCY IN THE ELECTRONIC ENGINE CONTROL MODULE (ECM) AFFECTING THE PROCESSING OF THE MASS FLOW RATE SENSOR THAT WILL CAUSE THE ENGINE TO UNEXPECTEDLY (AND WITHOUT A DASH WARNING INDICATOR) TO LOSE POWER. AT OCCURRENCE OF THE FAILURE, THE CAR WILL DECELERATE FROM HIGHWAY SPEED TO LESS THAN 35 MPH WITHIN A FEW SECONDS. FOLLOWING THE FAILURE, THE ENGINE RPM WILL NOT EXCEED 2,400 RPM AND SPEEDS ABOVE 35 MPH ARE IMPOSSIBLE (I FOUND THAT 4TH GEAR IS THE HIGHEST GEAR SELECTABLE). THIS FAILURE CAN BE DANGEROUS IN A NUMBER OF TRAFFIC SITUATIONS. I HAVE LEARNED FROM AN INFINITI SERVICE DEPT. THAT THE FAILURE WILL TEMPORARILY CORRECT ITSELF IF THE ENGINE IS TURNED OFF FOR A PERIOD OF TIME, BUT THAT THE FAILURE COULD REOCCUR. THE CAR'S ECM WAS RE-PROGRAMMED BY TOWBIN INFINITI (LAS VEGAS, NV) ON AUGUST 30 AND THAT SUPPOSEDLY FIXES THE FAILURE. WHILE AT TOWBIN, THE SERVICE MAN SAID THAT INFINITI KNOWS OF THE PROBLEM, BUT IS WAITING TO SEE HOW WIDE-SPREAD THE PROBLEM IS. OWNERS HAVE NOT BEEN TOLD OF THIS PROBLEM. TOWBIN SERVICE SAID THEY HAVE SEEN ABOUT 300 CASES OF THE PROBLEM. A SALT LAKE CITY DEALER SERVICE DEPT. HAD ALSO HEARD OF THIS PROBLEM. AGAIN, I FEEL THIS PROBLEM CAN BE DANGEROUS, BECAUSE: IF IT WERE TO OCCUR IN HEAVY TRAFFIC, IT MAY BE DIFFICULT TO GET OUT OF THE WAY OF OTHERS; IF IT WERE TO OCCUR WHEN TURNING IN FRONT OF ONCOMING TRAFFIC; AFTER IT OCCURS, THERE IS NO WAY TO KEEP UP WITH HIGHER SPEED TRAFFIC - ONE IS LEFT GOING SLOW AND HOPING NO ONE REAR ENDS ME; WITHOUT MORE INFORMATION, I HAVE NO WAY OF KNOWING IF THE PROBLEM HAS REALLY BEEN FIXED. *TR

1. I WAS DRIVING MY 2009 INFINITI G37XS ON I-95 NEAR PHILADELPHIA. I WAS USING CRUISE CONTROL WITH SPEED SET AT NEAR 65MPH. I WAS LISTENING TO PANDORA INTERNET RADIO ON MY HTC EVO 4G ANDROID PHONE USING WIMAX (4G WIRELESS). THE HTC EVO WAS BEING CHARGED USING A CELLET PMOTQ9C CAR CHARGER FOR CELL PHONES. 2. OUT OF BLUE, ALL ELECTRICAL AND ELECTRONIC SYSTEM WENT BLACK. ALL DASHBOARD DISPLAY(LCD), ENTERTAINMEN/NAVIGATION SYSTEM AND AC AND LEFT/RIGHT TURN SIGNAL AND LIGHTING ALL WENT OUT. NOTHING ELECTRONIC WORKS INCLUDING TURN SIGNAL/EMERGENCY LIGHT. I WAS QUITE NERVOUS, BUT DIDN'T WANT TO STOP AT MIDDLE OF INTERSTATE FREEWAY AND DRIVE STRAIGHT HOME AND PRAYED THAT POWER TRAIN STAY WORKING TILL I GOT HOME. THANK GOD, IT DID. AS SOON AS I STOPPED THE CAR BY PRESSING THE START/STOP BUTTON AFTER I DROVE INTO MY GARAGE, I WAITED A MINUTE OR TWO AND TRIED TO START MY CAR BY PRESSING THE START/STOP BUTTON WHILE PRESSING THE BREAK PEDAL. THE CAR WOULD NOT START. I THOUGHT THAT MY WIRELESS CARD KEY HAD BAD BATTERY. SO I SPENT 15MIN OR SO TO FIND MY 2ND WIRELESS CARD KEY AND STRANGELY ENOUGH I WAS ABLE TO START THE CAR. HOWEVER, THE "SERVICE ENGINE SOON" LIGHT ON DASHBOARD WENT ON. I CALLED THE DEALER SERVICE AND WANTED TO BRING THE CAR. BUT DEALER DIDN'T HAVE ANY LOAN CAR AVAILABLE TILL NEXT TUESDAY. SO I WAITED AND DROVE CAREFULLY WITH MY CAR AND BROUGHT IT TO DEALER ON THE FOLLOWING TUESDAY. AGAIN STRANGELY, JUST ONE DAY EARLIER, THE "SERVICE ENGINE" LIGHT DISAPPEARED. I TRUSTED DEALER HAD RIGHT EQUIPMENT TO DIAGNOSE. 3. DEALER TOOK A FEW DAYS LOOKED AT IT AND COULD ONLY TOLD ME SOME LIMITED DIAGNOSTIC INFO ABOUT LOSS OF COMM AND COULD NOT PIN POINT THE ROOT CAUSE OF PROBLEM. I EXPRESSED MY SAFETY CONCERNS ON AT NIGHT DRIVING ON I-95 SITUATION WHEN THIS HAPPENS AGAIN. THE DEALER ASSURED ME THAT ALL TESTS WERE DONE AND NO PROBLEM WAS FOUND AND THE CAR WAS SAFE TO DRIVE. 4. I DON'T FEEL COMFORTABLE AND FEEL THAT MAYBE NHTSA CAN BETTER INVESTIGATE THIS. *TR

TL*THE CONTACT OWNS A 2009 INFINITI G37. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 55 MPH, THE VEHICLE SUDDENLY DOWNSHIFTED TO APPROXIMATELY 10 MPH AND ALMOST CAUSING A CRASH. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALERSHIP WHERE A CHIP WAS CHANGED. HOWEVER, THE FAILURE OCCURRED THREE MORE TIMES. THE DEALER THEN STATED THAT THE FLUID IN THE VEHICLE WAS TOO FULL AND WAS THE CAUSE OF THE FAILURE. THE VEHICLE WAS AT THE DEALERSHIP AT THE TIME OF THE COMPLAINT AND THE CONTACT WANTED TO TRADE IT IN FOR ANOTHER VEHICLE. THE FAILURE MILEAGE WAS UNKNOWN. THE CURRENT MILEAGE WAS APPROXIMATELY 12,000.

2009 INFINITI G37 HAS ELECTRICAL WIRING INSULATION MADE OF SOY-BASED POLYMER. SOY BASED POLYMER IS APPARENTLY BIODEGRADABLE. THE PROBLEM IS THAT IT IS ALSO ATTRACTIVE TO RODENTS, WHO EAT THE WIRING, CREATING ELECTRICAL SAFETY HAZARDS. IN ADDITION TO THE SAFETY HAZARDS, IT ALSO CREATES AN ECONOMIC STRESSOR ON CONSUMERS AND INSURERS WHO HAVE TO PAY FOR REPAIRS DONE TO THESE AUTOMOBILES, WHICH INFINITI CLAIMS IS NOT COVERED UNDER ANY EXISTING WARRANTY. *TR

THE MANUAL TRANSMISSION IN MY 2009 INFINITI G37S STARTED GRINDING GEARS NEARLY EVERY TIME THE TRANSMISSION WAS PLACED IN 6TH GEAR. THIS RESULTED IN LONGER THAN NECESSARY GEAR CHANGES AT HIGH SPEEDS AND PROLONGED TIME WITH ONLY ONE HAND ON THE STEERING WHEEL. THE CAR WAS NEVER DRIVEN EXCESSIVELY ROUGH. THIS PROBLEM STARTED AT ~6000 MILES ON THE ODOMETER. AT ~8500 MILES, I TOOK THE CAR IN FOR REPAIR. INFINITI REPLACED THE TRANSMISSION WITH A NEW TRANSMISSION UNDER THE FACTORY WARRANTY AT NO COST TO ME. *TR

2009 INFINITI G37X COUPE IS EXPERIENCING DANGEROUS SURGES IN ACCELERATION UPON BRAKING, THE TRANSMISSION IS JERKING AND GOING INTO "FAIL SAFE MODE" (MEANING SUDDENLY THE CAR IS STUCK IN THE HIGHEST GEAR), THE REAR DIFFERENTIAL IS CLUNKING AND JERKING AS IF THE CAR IS GOING INTO AWD MODE AT TIMES IT SHOULD NOT BE, AND QUITE FRANKLY I AM NOW BECOMING SCARED OF THE CAR. IT HAS 3800 MILES ON IT. I TOOK IT INTO THE DEALERSHIP ON FRIDAY AND WAS TOLD THERE ARE A COUPLE OF KNOWN ISSUES WITH THE TRANSMISSION BUT NO FIX. THEY ALSO ARE CALLING HQ ON MONDAY TO TALK ABOUT IT. I DO NOT WANT TO LEAVE MY CAR TO BE DRIVEN AROUND ERRATICALLY AS THEY TRY TO "BREAK" IT AS THAT WILL CAUSE FURTHER DAMAGE TO THE TRANSMISSION AND ENGINE AS WELL AS PUT MORE MILES ON THE CAR. INFINITI SERVICE AGREED THAT REMAPPING THE COMPUTER WOULD MOST LIKELY TAKE AWAY THE SPECIFICATIONS OF THE CAR WHICH ARE WHAT THEY MARKET AND I BOUGHT THE CAR FOR (HORSEPOWER, ACCELERATION, "SAME AS A BMW". IF THEY HAVE TO GUT THE POWER OF THE CAR TO FIX THE PROBLEM, I FEEL THIS IS FALSE ADVERTISING AND THE CAR IS NOT WHAT I CONTRACTED TO PURCHASE. I AM ON THE VERGE OF WATCHING MY RESALE PLUNGE BEFORE THE CAR IS EVEN SIX MONTHS OLD AND BELIEVE INFINITI SHOULD HAVE TO REPLACE THE VEHICLE. THIS PROBLEM IS HAPPENING REPEATEDLY EVERYTIME I DRIVE THE CAR. SEE NOTES BELOW: 1. CENTRAL COMPUTER CLEARLY FAILING - HAD TO BE RESTORED YESTERDAY. 2. REAF DIFF CLUNKING IN AND OUT OF AWD LOUDLY AND WITH A JERK AND AT UNEXPECTED TIMES 3. SURGING RPMS AS MUCH AS 5000 UPON DRIVING 4. SURGING RPMS AND ACCELERATION UPON BRAKING (3000 RPM) 5. HANGING INSTEAD OF DOWNSHIFTING 6. VERY JERKY DOWNSHIFTS 7. TRANNY WENT INTO FAILSAFE AT LEAST 3 TIMES NOW (MEANING NO GEAR BELOW 5TH IS AVAILABLE AT ANY TIME). *TR

I OWN A TWO-MONTH OLD INFINITI G37X. WHEN BRAKING AT HIGHWAY SPEED, THE ENGINE DOES NOT SEEM TO SLOW DOWN AS FAST AS IT SHOULD. I BROUGHT THIS TO MY INFINITI DEALER THIS WEEK. THEY CONDUCTED TESTS ON IT AND FOUND THAT IT "PERFORMS AS DESIGNED." HOWEVER, THEY ACKNOWLEDGED THAT THE TRANSMISSION DOES NOT SLOW DOWN WHEN THE BRAKE IS APPLIED - THAT THE ENGINE IS DESIGNED TO "CLICK DOWN" FROM GEAR TO GEAR. BUT WHEN BRAKING HARD AT A HIGHWAY SPEED, THE CAR DOES NOT SLOW DOWN IMMEDIATELY BECAUSE OF THIS DESIGN. I'VE BEEN DRIVING FOR 33 YEARS AND HAVE NEVER BEFORE FELT LIKE THE CAR WAS NOT GOING TO STOP WHEN IT NEEDED TO. THIS CAR GIVES ME THAT FEELING. I'VE HAD TO STOP QUICKLY A COUPLE OF TIMES ON THE HIGHWAY AND I DID NOT FEEL AS THOUGH I WAS IN CONTROL OF THE CAR. INFINITI'S TESTS SEEM TO CONFIRM THIS. HOWEVER, THEY DID NOT OFFER ANY SORT OF REPAIR BECAUSE, AGAIN, THE CAR IS REACTING AS DESIGNED. THEY DID SAY THAT A SOFTWARE CORRECTION MIGHT OCCUR IN THE FUTURE BECAUSE CORPORATE INFINITI IS AWARE OF THIS PROBLEM. *TR
