2004 Infiniti QX56 problems

“My wife was driving home from work, said brake is failing, makes loud grindy, rattling noise when brake is applied. Once the car is turn off and back on, everything is back to normal. When I got home, i took the wheels off to check everything was ok, pads were almost new, which I replaced last year. Drove around for 10 miles no problem. This is a serious safety issue which Nissan/Infiniti should take care of.”

“DRIVING WITH MY TWO YOUNG CHILDREN ABOUT 35 MPH WHEN I DEPRESSED THE BRAKES THE CAR SHUTTERED BADLY ON THE FRONT END AND THE PEDDLE WENT ALL THE WAY TO THE FLOOR AND THE VEHICLE BARELY SLOWED DOWN. LUCKILY THERE WAS NO-ONE IN FRONT OF ME OR I WOULD HAVE CRASHED. PROBLEM CONTINUED UNTIL THE VEHICLE WAS TURNED OFF AND RE-STARTED. EXTREMELY DANGEROUS!!! MANY OTHER SIMILAR ACCOUNTS AND IT DOESN'T SOUND LIKE THERE IS A DIFINITIVE RESOLUTION TO THE PROBLEM EVEN AFTER SPENDING THOUSANDS AT THE DEALERSHIPS. *TR”

“TL* THE CONTACT OWNS A 2004 INFINITI QX56. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE SUDDENLY SHUT OFF. IN ADDITION, THE FUEL GAUGE AND OTHER GAUGES ON THE INSTRUMENT CLUSTER DISPLAYED INACCURATE INFORMATION. THE VEHICLE WAS TAKEN TO A LOCAL DEALER (INFINITI OF ELK GROVE, 8586 LAGUNA GROVE DR, ELK GROVE, CA) WHERE IT WAS DIAGNOSED THAT THE ELECTRONIC CONTROL UNIT WAS FAULTY AND NEEDED TO BE REPLACED; HOWEVER, THE PART WAS NO LONGER AVAILABLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 167,000.”

“WHILE DRIVING DOWN THE ROAD ON SUNDAY, JULY 19TH, 2015. THE LIGHT FOR THE AIR BAGS STARTED BLINKING OUT OF THE BLUE. NOW EVERY TIME I GET IN THE SUV TO GO SOMEWHERE IT STAYS BLINKING.”

“The contact owns a 2004 Infiniti QX56. The contact stated that the vehicle would fail to start up after multiple attempts with several unknown warning lights illuminated on the instrument panel. In addition, he stated that the vehicle would intermittently stall while driving at various speeds with several unknown warning lights illuminated on the instrument panel. The contact had taken the vehicle to a dealer where they informed him that his vehicle was not included in NHTSA Campaign Number: 10V517000 (Engine and Engine Cooling). The contact was referred to NHTSA for assistance. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 68,000.”

“EMERGENCY BRAKE: E-BRAKE APPEARS TO ENGAGE ON ITS OWN AND THE BRAKE LIGHT INDICATOR COMES ON. THERE'S ALSO A GRINDING SOUND WHEN BRAKE IS PRESSED. GRINDING SOUNDS ONLY OCCURS WHEN THIS ISSUE COMES UP. EXHAUST MANIFOLDS: WAS NOTIFIED BY THE DEALER UPON A SERVICE INSPECTION THAT THERE WAS A SMALL CRACK IN THE EXHAUST MANIFOLDS. IS THIS A NORMAL THING? AND SHOULD THIS BE A RECALL ITEM AS IT COULD THROW OFF ANY SMOG CHECK TESTING. IN ADDITION HOW ABOUT THE EXHAUST IN THE CABIN ISSUE? MAYBE THEY USED TOO THIN OF A METAL FOR THE MANIFOLDS.”
