Electrical system
9 reports
“I've had 2 incidents where my vehicle has stopped and not restarting. I took it to the dealership, and they stated I needed a starter. I see there are several complaints regarding this issue with the model QX80. Ive also had to get 2 new batteries with 1 year. Please look into the issues. I went to the dealership on 8/18/2026 they said my vehicle didn't start . My vehicle did start and I took it to another repair shop and save over 1300.00 To say my car wouldn't start and it did . I'm glad it did so I didn't have to pay so much for and it was done in less than 1hr”
Fuel/propulsion system
2 reports
“Fuel gauge erratically and inaccurately showing different levels of fuel- sometimes full, empty or anywhere in between. Potential risk of running out of gas and not knowing. Recalls are listed for other vehicle model years but not this one. No warning messages appear on dashboard. First noticed the problem Feb 2025 and continues to worsen. It has not been seen by a mechanic or dealership yet since first experiencing.”
Visibility/wiper
2 reports
“The night rear backup camera is extremely dark and blurry. You can’t see anything via the camera at night.”
Back over prevention
2 reports1 related recall
“The backup camera cannot see see at nighttime, a real safety issue.”
Service brakes
2 reports
“THE 2019 QX80 FORWARD EMERGENCY BREAKING SYSTEM (FEB) CONTINUOUSLY ENGAGES THE BRAKES WITHOUT WARNING OR AN OBSTRUCTION. ALWAYS WHILE A RAILROAD CROSSING IS IN SITE, SOMETIMES WHEN A REDLIGHT IS NEAR BUT (GREEN) WITH NO VEHICLES STOPPED AT IT. IT HAS ALSO DONE IT ON AN OPEN HIGHWAY & INTERSTATE AT SPEEDS OF 70 MPH WITH NOTHING AROUND. THIS CAUSES A VERY REAL CHANCE OF BEING REAR-ENDED, OR STARTELING THE DRIVER INTO CRASHING.”

“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!”
