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 30,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 model year marks the starting point of the provided federal record, exhibiting significantly higher scrutiny than subsequent years with 118 complaints and 11 recalls compared to just 33 complaints and 8 recalls in 2019. A clear downward trajectory is evident across the generation, as complaints drop steadily from 118 in 2018 to single digits by 2020, while Technical Service Bulletins decrease from 142 to 55 by 2022. Specific federal records for 2018 highlight Fuel System, Gasoline as the leading complaint area with 19 reports, alongside 10 Engine complaints and 3 fire-related complaints, though the data does not specify the root cause for these incidents. This arc implies that the 2018 model year bears the brunt of initial model year issues that were largely mitigated in later model years, as evidenced by the sharp reduction in complaints and recalls after the first year. Consequently, unless priced significantly lower than later models to account for potential repairs, the 2018 Stelvio is a higher-risk purchase than the stabilized 2020 or 2021 model years.
