Is the Alfa Romeo Giulia Reliable?
Later models from 2020 onward are noticeably more refined and have improved reliability. Early cars (2016 to 2018) were more prone to electrical issues, infotainment faults and trim rattles. However, the engines and drivetrains are generally robust if serviced on time. Software updates and battery health are key to keeping faults to a minimum.
