2018 Infiniti QX30

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 QX30.

Body PASSENGER CARTransmission Automatic (AM7)

The 2018 Infiniti QX30 is a passenger‑car‑class crossover that pairs its automatic AM7 transmission with a modestly sized powertrain requiring 6.0 qt of 0W‑30 oil, delivering an EPA rating of 24 mpg city, 33 mpg highway and a combined 27 mpg. While the model’s overall owner‑complaint count sits at 22 and it has been subject to three recalls, the most frequent issues fall under an “Unknown or Other” category rather than a specific system. Within its three‑year complaint window (20172019), the 2018 year falls between a peak of 32 complaints in 2017 and a low of just three in 2019, suggesting a middle‑ground position in the model’s reliability trajectory.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 45,000 mi; coolant at 155,000 mi. The big-interval services (at 155,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 20172019 Infiniti QX30 generation exhibits a clear downward trend in reported issues, with complaints falling from 32 to 3, recalls from 4 to 1, and TSBs from 137 to 56 across the three model years. The 2018 model, with 22 complaints and 3 recalls, sits in the middle of this arc, representing a meaningful improvement over the debut 2017 year but not yet reaching the minimal levels of the final 2019 model. Its top complaint areas are sparse and non-specific, led by two "Unknown Or Other" reports and no crash or fire incidents, suggesting no widespread or severe defects. This indicates that many early production concerns were being addressed by 2018, making it a more refined choice than the 2017 version. For a used buyer, the 2018 QX30 offers a good balance of reduced early issues and likely lower cost compared to the 2019, making it a solid purchase.
