NHTSA complaint #11662446 — an unverified report by a vehicle owner.
There was previous recall on this vehicle, 10V-074 (Infiniti #R1011) for a fuel sender problem, causing the fuel gauge to be inaccurate. Infiniti says it was fixed in 2010. Unfortunately, I am having the exact same problem now, and have run out of gas twice because of it. Infiniti said they can't help because it was already fixed. Safety issue because running out of fuel while driving is dangerous. Both times has been on an interstate. It was a previously reported recall and "fixed" but has failed again. Infiniti says they won't fix it again.

NHTSA complaint #11388665 — an unverified report by a vehicle owner.
ON JUNE 1ST 2020 I TOOK MY 2011 INFINITI QX56 TO THE SHOP FOR HAVING THE CODE P0087. THE SHOP TOLD ME THAT I SHOULD TAKE IT TO THE DEALERSHIP BECAUSE THE PROBLEMS THE VEHICLE IS HAVING ARE RECALLED UNDER VOLUNTARY SAFETY RECALL CAMPAIGN. WHEN I CALLED MY LOCAL INFINITI DEALERSHIP THEY TOLD ME MY VIN # DOESN'T DOESN'T SHOW AS RECALLED. THEY DEALERSHIP PROVIDED ME WITH THE PHONE NUMBER OF INFINITI CONSUMER AFFAIRS. I CALLED INFINITI AFFAIRS AND TOLD THEM ABOUT MY VEHICLE THEY TOLD ME THAT THEY WERE SORRY BUT MY VIN DOESN'T SHOW UP ON THEIR SYSTEM. THE BOTTOM LINE IS THAT EVERY SINGLE THING THAT I RESEARCHED AND FIND THE WRONG OF THE VEHICLE COMES BACK WITH A VOLUNTARY RECALL. LIKE THE FUEL SYSTEM, TIMING CHAIN, VVT SOLENOIDS, HIGH PRESSURE FUEL PUMP. I USE VEHICLE IN THE CITY AND HIGHWAY.

THE FUEL GAUGE MAY BE SLOW TO REGISTER, FAIL TO READ FULL WHEN THE GAS TANK IS ACTUALLY FULL, OR READ INACCURATELY. WHEN FILLING GAS TANK TO FULL, AFTER 30 MILES THE GAUGE IS READING 2/3 OF A TANK OR LESS WHILE THE MILES TO EMPTY READING IS STILL HIGH.

MY TRUCK COMPLETELY SHUTS OFF WHILE DRIVING LONG DISTANCES ON THE FREEWAY AT SPEEDS GREATER THAN 60 MPH AND THEN SLOWING DOWN IN STOP AND GO TRAFFIC. IT ALSO FALLS DEAD ON LOCAL ROADS AT 30-40 MPH. I CAN LITERALLY PRESS THE GAS PEDAL TO THE FLOOR AND WITH NO PRESSURE TO THE ACCELERATOR. THERE ARE NO WARNING CODES OR ALERTS WHEN THIS HAPPENS. I TOOK MY VEHICLE TO THE SOUTHWEST INFINITI PAID FOR UNNECESSARY SERVICE AND THE PROBLEM STILL REMAINS. I AM ABLE TO RESTART THE VEHICLE;BUT FROM ONLY PARK OR NEUTRAL. I THEN HAVE TO REV UP THE ENGINE FOR AT LEAST 5 MINS BEFORE I AM ABLE TO GET ANY TYPE OF ACCELERATION. THIS IS VERY DANGEROUS AND I ALMOST GOT HIT SEVERAL TIMES.

LESS THAN A YEAR AFTER I GOT THE TIMING DEBACLE FIXED, I GET A "CHECK ENGINE LIGHT" ON 2011 QX56. ACCORDING TO MY WARRANTY APPROVED MECHANIC BOTH CATS WERE GONE AND WERE NOT COVERED. THIS COMPLAINT IS THE BEGINNING OF MY GOAL OF GETTING ASSURANT OR INFINITI TO OWN THIS PROBLEM SINCE THE COMBINED CA AND FED CAT WARRANTY IS 150K MILES. MY WARRANTY SHOULD COVER.
