What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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 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.
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.
The night rear backup camera is extremely dark and blurry. You can’t see anything via the camera at night.
The backup camera cannot see see at nighttime, a real safety issue.
Today, I went to my sons soccer game and guess what, battery dead yet again! I have never in my life had an issue like this. This is an 80,000 vehicle and completely unacceptable to have had this happen 3 times in 6 months.
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.
Also being told the qx80 is not meant to sit without being driven for a week or longer, as this can cause the battery to drain enough it will not start. So I used the example that I cannot leave the qx80 at the airport if I was flying out and going on vacation for a week. They recommended that I do not do that.
