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
NHTSA complaint #11758084 — an unverified report by a vehicle owner.
Summary: Recurring weak/no-start condition due to low battery voltage despite new battery replacement. Charging system (VVCS) fails to adequately maintain battery charge on normal driving patterns. -Purchased certified pre-owned vehicle Dec 2024. -Began experiencing weak battery (weak or no starts) approximately Jul 2025. Jump started and charged for a few months, as issue was intermittent. -Symptoms got worse, brought vehicle to dealer Nov 2025. Battery tested bad and replaced by dealer. -Experienced weak battery again June 2026. Voltage readings: 12.16V resting, drops to ~12V while driving after initial 15V spike. Charged battery with battery charger. -Took vehicle to dealer again 6/29/26. Dealer confirmed smart charging behavior, no parasitic draw, no codes, good battery (had been recently charged), good alternator.

NHTSA complaint #11747704 — an unverified report by a vehicle owner.
What component or system failed or malfunctioned, and is it available for inspection upon request? Two components have failed: the infotainment/Apple CarPlay system, including the USB-C connectivity port, and the front collision detection/crash sensor system. The entire A/V unit was replaced on August 1, 2025, yet the infotainment defect persisted. Both systems are currently installed in my vehicle and are available for inspection upon request. How was your safety or the safety of others put at risk? The front collision detection system malfunction directly compromises my ability to rely on the vehicle's built-in safety features to prevent or mitigate crashes. Additionally, the infotainment screen has frozen and reset while the vehicle was in motion. I have also been locked out of my vehicle twice while the engine was running, which created a dangerous situation. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. On July 25, 2025, a technician at Georgetown Infiniti attempted and failed to connect their own phone to the CarPlay system, confirming the defect was in the vehicle and not my personal device. The collision system malfunction has been documented across multiple service visits at both Georgetown Infiniti and Grubbs Infiniti. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle has been inspected and serviced by authorized Infiniti dealerships, specifically Grubbs Infiniti and Georgetown Infiniti, both of which are manufacturer-authorized service centers. Most recently addressed 2/4/20226. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The infotainment screen displayed warning messages, froze, and reset while driving. The front collision system displayed malfunction warnings on the dashboard.

Vehicle acting as a non conforming testing asset running in Factory Debug Mode (Unit ID: 01). This also shows and caused systemic U1000 Electrical Network Jam from an obsolete/unconfigured 2G TCU. Critical Failures: Airbags disabled showing current codes B0022-13(Left), B002A-13(Right) prove the primary curtain airbags are open/offline and won't deploy. Adaptive System Failure: Around View Monitor running Alpha Software(000154) which fails to lock out forward camera at highway speeds creating driver distraction. Ignition Hijack: Code B2401(Ignition Open) allowed vheichle to "Ghost Start" and recognize keys even when sealed in Faraday pouces. Voltage trauma: Sysemic VB Low (B142A-16) prevents vehicle from entering sleep mode, causing persistent network noise. The vehicle was sold as retail but remains in "Unconfigured" Manufacturing state Code: U122A-05. This violates FMVSS 208 and 49 USC Section 30112. AV Control Unit reveals Unit ID 01 and switch software 11401. It remains unconfigured in dubug mode Code: U122A-05, which should have never been for sale FMVSS208. Despite the airbags disabled and network jam codes, Matt Bowers Infiniti Advisor attempted to release vehicle with fraud estimate of $9930.75 for unrelated hardware, and overwrite EEPROM evidence of debug mode.

Odometer Fraud. The contact purchased a 2017 Infinity QX80. The contact discovered a mileage discrepancy after the purchase. The vehicle was a private sale. The seller had an LLC. At the time of purchase, the mileage was 90,743. It was later discovered that the mileage on the Title was 175,074 on January 6, 2026. The third-party warranty company that the contact hired discovered the discrepancy and informed the contact that the vehicle had a branded title.

Camera monitoring system or rear visibility system. The rearview/backup camera has intermittently malfunctioned in my QX80 numerous times since I purchased the car in February 2024, including (1) displaying a frozen image from the backup camera when putting the car in reverse which stayed frozen (for example, did show a car driving directly behind me which I almost hit) and displayed the frozen image to the driver the entire time driving the car, including at highway speeds, and which could not be manually removed from view (including by pressing the camera button); and (2) the backup camera not turning on at all when the QX80 is put in reverse, not could the backup camera be turned on manually by pushing the camera button. I attached some photos of the frozen rearview/backup camera which remained displayed to the driver the entire time driving the car, including while traveling on the interstate at highway speeds (65 mph) when the photos were taken attached below. The date below is the date of the photo, however backup camera malfunctions has occurred numerous times and dates. I also have numerous videos of the malfunctions described herein that I can also share.
NHTSA complaint #11693639 — an unverified report by a vehicle owner.
Ongoing failure to start, multiple battery replacements in less than 2 years. Purchased a warranty and of course the vehicle will not replicate its failure to start when it is at the dealership for the warranty claims adjustor to review. Car has had to be towed to the dealership with no resolution even after being there multiple times. Dashlights have gone dim - issues with multiple lights coming on. Dash on order - been waiting months now with no update on when the new dash will arrive. Multiple TSB's have been issued regarding the issues mentioned - TSB ITB19-034b TSB MC-10239504 with no resolution. Infiniti is aware of these issues and has only offered to bypass "jump out" or bypass of the IPDM (Intelligent Power Distribution Module), noting that this action would void my warranty related to that specific issue. This is unacceptable. Infiniti serviced my vehicle in August and September no issues with the battery - but then it failed in October. A new battery had to be purchased in Oct after a visit by AAA.
NHTSA complaint #11691698 — an unverified report by a vehicle owner.
I am writing to report serious safety concerns regarding my 2017 Infiniti QX80. The vehicle has exhibited two primary issues: 1. Unintended Braking: The vehicle has a tendency to suddenly and unexpectedly brake, particularly when driving over specific road surfaces, such as brick-paved intersections. This behavior is extremely dangerous as it can lead to accidents, especially in high-traffic areas. Such abrupt braking can cause the vehicle to lurch forward, potentially leading to rear-end collisions. 2. Frequent Battery Drain and Failure: The vehicle's battery drains rapidly, requiring frequent replacement. Despite multiple visits to the dealership and attempts at repair, the issue persists. This problem significantly compromises the vehicle's reliability and can leave the driver stranded, particularly in emergency situations. I have taken the vehicle to an authorized Infiniti dealership multiple times to address these issues. While the dealership has attempted repairs, the problems have persisted. The frequency and severity of these issues pose a significant safety risk to myself and other drivers. I urge the NHTSA to investigate these issues and take appropriate action to ensure the safety of all 2017 Infiniti QX80 owners.

Similar to other complaints, the instrument cluster lighting is beginning to go dim or completely out starting at the high end of the RPM gauge and the low end of the speedometer gauge. This is an issue during night time driving.
NHTSA complaint #11607960 — an unverified report by a vehicle owner.
The primary instrument gauge for the QX80 starts to lose illumination from around the speedometer and tachometer. The vehicle has 55,000 miles and is a 2018 model. This is the SECOND time this has happened, with the instrument gauge being replaced first at approximately 32,000 miles for the same reason. Currently the instrument gauge is continuing to lose lighting - making the speedometer impossible to see at night (SAFETY ISSUE). Infiniti Dealership reports that there is a +/- 2 YEAR waitlist for replacement instrument clusters, and that this is a known problem. The same dealership that replaced it a few years ago. This 2nd instrument cluster started going out in the 20-45 mph segment, then 6500-8000 rpm tach, then 0-20 mph.

Something keeps killing my battery. There’s no lights that come on to indicate a problem. I’ve been stranded twice at work and now today, I get ready to leave and the battery is dead again!! I’ve gotten a new battery three times in a year’s time. I’ve searched for a recall because I see where others are having the same problem, but apparently there’s not one. Hopefully, the dealership will have some answers tomorrow.

I PURCHASED A 2016 QX80 LAST WEEK. AFTER FILLING MY CAR WITH FUEL, WITHIN 10 MINUTES, MY GAS GAUGE WENT FROM FULL, TO DOWN 3/4 OF A TANK OF GAS. AFTER ONLY 50 MILES OF DRIVING, WITH NO AIR CONDITIONING ON, I'M AT 1/2 OF A TANK ACCORDING TO MY FUEL GAUGE. THERE IS ABSOLUTELY NO WAY THAT CAN BE CORRECT.

I HAVE HAD THIS VEHICLE FOR A LITTLE OVER A YEAR AND SINCE APRIL, I HAVE BEEN STRANDED IN DIFFERENT PLACES. THE REASON IS BECAUSE I WOULD GO TO GET IN MY CAR AND THE BATTERY WAS COMPLETELY DEAD. THE FIRST TIME THIS HAPPENED, THE DEALERSHIP SAID IT WAS A RECALL ISSUE THAT THEY CLAIMED TO FIX. THIS HAPPENED AGAIN 3 MONTHS LATER, AT NIGHT WITH MY BABY AT THE GROCERY STORE. I WENT TO GET INTO MY CAR AND BATTERY WAS DEAD YET AGAIN. TOOK IT THE DEALERSHIP AND THEY TRIED TO TELL ME IT WAS MY FAULT BECAUSE I DON'T DRIVE IT ENOUGH. MIND YOU, I DRIVE MY VEHICLE EVERY SINGLE DAY TO WORK AND TO DAYCARE ETC. AFTER FIGHTING WITH THEM FOR A WEEK, THEY FINALLY FIXED IT, OR SO I THOUGHT. 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. I BOUGHT THIS CAR FOR SAFETY PURPOSES FOR ME AND MY BABY, AND IT IS LITERALLY THE EXACT OPPOSITE OF WHAT I NEEDED. I HAVE BEEN STRANDED WITH MY BABY 3 TIMES!!! THIS VEHICLE IS AN ABSOLUTE JOKE AND I BEG ANYONE READING THIS TO NEVER PURCHASE IT! I WILL BE SPEAKING TO AN ATTORNEY REGARDING LEMON LAWS. I WANT MY MONEY BACK AND I WILL NEVER PURCHASE AN INFINITI AGAIN.
