How long Alfa Romeo engines last depends heavily on maintenance discipline, driving habits, and the specific model in question. On average,a well-maintained Alfa Romeo engine can last between 150,000 and 200,000 miles. Models equipped with the 2.0L turbocharged GME engine, found in the Giulia and Stelvio, have shown reasonable reliability when serviced regularly. Historically,Alfa Romeo engines have had a reputation for complexity and sensitivity to neglected maintenance. Timing belt or chain intervals, oil change frequency, and coolant system upkeep are critical factors. Owners who follow manufacturer service schedules and use quality fluids consistently report fewer long-term Alfa Romeo engine problems.
