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 Alfa Romeo Giulia recorded 84 federal complaints, nine recalls and one investigation, exceeding the 65 complaints and five recalls of the 2017 model and the 42 complaints and seven recalls of the 2019 model. This peak in complaints and recalls aligns with a generation‑wide arc that shows complaints rising to a high in 2018 before declining in subsequent years. The 2018 model’s top complaint categories — Fuel/Propulsion System (15), Fuel System, Gasoline (7), Engine (5) and Electrical System (5) — highlight fuel‑related concerns that also appear in the crash (6) and fire (1) complaint counts. The data does not specify a root cause for these issues, only that they are documented in the federal record. Consequently, the 2018 year is not the optimal choice for a used purchase compared with later model years.
