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; 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 Alfa Romeo Stelvio exhibits significantly higher instability than subsequent model years, recording 118 complaints and 11 recalls compared to just 4 complaints and 2 recalls for the 2022 model. Across the generation's record, there is a sharp downward trend in complaints, suggesting that the 2018 model represents the peak of reported issues. For the 2018 model, the most frequent complaints center on the fuel system, gasoline (19), fuel/propulsion system (10), and engine (10), though the data does not specify the root causes of these failures. This target year also recorded 142 TSBs, 3 crash complaints, and 3 fire complaints. Because 2018 sits at the highest point of the generation's complaint and recall arc, it is not a recommended year to buy.
