2018 Audi Q7

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Q7.

Body SUV

The 2018 Audi Q7 is an SUV that requires 5.4 to 5.5 quarts of 5W-40 engine oil, a precise specification for researchers tracking its service requirements. In terms of reliability, this iteration generated 140 owner complaints alongside three recalls, with the engine serving as the top complaint area. While this represents a notable decline from the preceding 2017 model's historical peak of 316 complaints, the 2018 still sits well above the model's lowest-complaint years like 2024, indicating that owners face a higher probability of encountering issues compared to the most reliable versions of the vehicle.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 60,000 mi; coolant every 20,000 mi. The big-interval services (every 20,000 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 2018 Audi Q7 sits in the middle of a sharp reliability arc within the second-generation model (2017+). The 2017 launch year recorded a massive 316 complaints and 7 recalls, making it the worst year in the entire dataset. The 2018 model drops to 140 complaints and 3 recalls—a clear improvement—but still remains elevated compared to the 2019 (61 complaints, 4 recalls) and 2020 (25 complaints, 5 recalls) model years. The top complaint areas for 2018 are engine (27), exterior lighting (17), and suspension (14), with 3 crash-related complaints and no fires reported. The data does not specify root causes for these issues, but the complaint and recall trend shows the 2018 as a transitional year: better than the problematic 2017 but not yet as settled as the 2019–2020 models. For a used-car buyer, the 2018 Q7 is a reasonable choice if you prioritize lower price over maximum reliability, but you should budget for potential engine and lighting repairs and verify that all three recalls have been performed.
