Infiniti G37 Power Train Safety Report | July 01, 2011
Reported on July 01, 2011
| 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 | |
