For the 2014 Infiniti QX80, engine and fuel system complaints make up the bulk of what owners report. On the engine side, owners describe grinding or winding noises, abnormal vibrations, and illuminated check engine lights, with timing chain failure coming up as a diagnosed cause in at least one case. The fuel system draws a separate cluster of complaints: high-pressure fuel pump failures are reported more than once, with owners noting the pump can fail and then continue causing problems even after a repair attempt. A handful of owners also describe a noticeable fuel odor while the vehicle is parked, sometimes strong enough to be detected indoors, without any warning light triggering.

Total Complaints
By System
The 2014 Infiniti QX80 has 3 recalls, the most serious being a driver's frontal airbag that may fail to deploy in a crash or whose inflator can rupture, potentially sending fragments into the cabin.
The remaining two recalls both involve incorrect information on the vehicle's certification label. On models equipped with 20-inch wheels, the label lists an incorrect rear axle weight rating, which could lead to overloading the axle. A separate filing covers vehicles where the label may also show the wrong rim diameter. Both issues are limited to certain production windows.
