Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2026 QX80.
The 2026 Infiniti QX80 is defined by its Automatic (S9) transmission and EPA fuel economy ratings of 16 city, 20 highway, and 18 combined mpg. With only three total owner complaints primarily targeting the service brakes and forward collision avoidance systems, alongside a single recall, the vehicle's early quality data remains tight. This places the 2026 model near the lowest complaint watermark of one set in 2022, a stark contrast to the twenty complaints recorded for the 2014 model year, meaning this current iteration represents a notably stable chapter in the nameplate's reliability history.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2026 Infiniti QX80 sits at the tail end of a generation that has seen a clear downward trend in owner complaints and technical service bulletins (TSBs) since 2014. Complaints peaked at 20 in 2014 and have since fallen to just 3 in 2026, while TSBs dropped from 154 to 5 over the same period—indicating that later model years have benefited from cumulative refinements. Recalls have also moderated: after a spike of 3 in 2025, the 2026 model has only 1 recall, matching the low seen in 2022 and 2023. The 2026 year reports zero crash or fire complaints, and its top complaint areas (brake/forward collision avoidance and back-over prevention) each have only a single report, suggesting no widespread or safety-critical issues. Compared to the 2025 model, which had 8 complaints and 3 recalls, the 2026 shows further improvement, and it aligns closely with the very low complaint counts of 2024 (2) and 2022 (1). Based solely on the federal record, the 2026 QX80 is a strong buy for a used luxury SUV, as it represents the most refined and least problematic year of this generation.
