Owner report 11291109 · 2019-12-24 (December 24, 2019)
WENT TO START CAR AFTER IT WAS SITTING OVER NIGHT (AND TEMPERATURE HAD DROPPED) AND IT WOULD NOT START, REQUIRING A JUMP. NOTHING WAS LEFT ON OVERNIGHT. CAR REQUIRED JUMP START TWO MORE TIMES UNTIL I WAS ABLE TO TAKE TO DEALER. I WAS TOLD IT WAS A DEFECTIVE BATTERY AND BATTERY WAS EXCHANGED. THREE WEEKS LATER, AFTER STOPPING FOR GAS AT 5AM ON WAY TO WORK, CAR WOULD NOT START AGAIN. AGAIN NOTHING HAS BEEN LEFT ON. CAR IS CURRENTLY DEAD IN MY DRIVEWAY. IT IS A 2019! ALSO, THE DOOR COVERING MY GAS CAP NO LONGER OPENS, REQUIRING IT TO BE PRIED OPE…

ON THREE OCCASIONS THE BATTERY IN MY 2019 QX80 HAS DIED FOR NO APPARENT REASON. THE CAR IS A 2019 AND THE BATTERY DIED 8 MONTHS, 10 MONTHS AND NOW 13 MONTHS AFTER PURCHASING IT BRAND NEW. EACH TIME THE CAR HAS DRIVEN FINE IN THE MORNING ON MY WAY TO WORK BUT WHEN I TRIED TO TURN IT ON TO HEAD HOME IT DIDN'T START. I WAS INITIALLY TOLD IT WAS A BAD BATTERY AND THEN TOLD IT WAS AN ALTERNATOR ISSUE. I HAVE TWO YOUNG CHILDREN AND AM NOW SCARED TO DRIVE THEM IN OUR FAMILY VEHICLE OUT OF FEAR OF BEING STRANDED AGAIN.

THE CRUISE CONTROL DOES NOT WORK GOING DOWN A HILL. IT WORKS ON A LEVEL ROAD. IT WORKS GOING UP A HILL. I SET IT AT SAY 50 MPH ON US ROUTE 30, BOSWELL, PA GOING DOWN A HILL AND WITHOUT APPLYING THE BRAKES THE VEHICLE WOULD BE GOING 60 MPH AT THE BOTTOM OF THE HILL. THIS IS DANGEROUS. DEALER TOLD ME NOT TO USE THE CRUISE CONTROL GOING DOWN A HILL!

Owner report 11549615 · 2023-10-12 (October 12, 2023)
This car has the SAME issue as explained in NHTSA Bulletin ITB17-008c for 2017-2018 year Infiniti QX80's but Infiniti will not diagnose and fix. Instead they are seeking nearly $4k in repair work. The torque converter should last up to 200k miles and my car started having this issue around 65k miles. Ive escalated to Infiniti HQ and they will not listen to my complaint and continually are telling me there is not a recall. This recall needs to be put into place for model year 2019, the issue is NOT fixed!
