What can fail
The fuel pump can fail, stopping fuel from reaching the engine and causing a loss of driving power.
This page covers 10 recalls, 80 owner complaints and EPA fuel economy for the 2018 Alfa Romeo Giulia.

Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 3 tested variants for this model year.
The most common thread running through 2018 Giulia complaints centers on the fuel and propulsion system and the engine. Owners frequently report sudden, unexpected power loss while driving, the car hesitates, then cuts out entirely, sometimes at highway speeds. Many describe an electronic throttle control fault triggering the stall or near-stall condition, and some note the vehicle struggles to accelerate afterward. Unintended acceleration also appears across several reports, with owners describing the engine revving abnormally at a stop or the vehicle surging and failing to slow when the brake is applied. A smaller cluster of engine-related complaints involves excessive smoke at startup, attributed to what owners describe as a fuel delivery issue causing an over-rich condition in the combustion chamber. Electrical system complaints round out the top three reported categories, though at lower volume. The power-loss and stalling pattern, particularly at speed, is the most consistently repeated symptom across this model year's complaint set.

By System
The 2018 Alfa Romeo Giulia has 10 recalls, the most serious being a fire risk on AWD models with the 280HP engine, where a brake fluid line can contact a coolant hose clamp and drip fluid onto the hot exhaust.
A second fire risk affects 2.0L engine models: the engine can misfire, causing the catalytic converter to overheat and damage nearby wiring and components, which can also lead to an engine stall. On the brake side, several recalls overlap: contaminated brake fluid may have been used during assembly and can degrade braking performance, carbon ceramic brake-equipped vehicles can develop excessive clamping force that fractures the rotor, and a software issue in the brake system module can prevent the driver from turning off adaptive cruise control after a wheel slip event. The fuel pump can also fail and cut drive power without warning. Two separate recalls address fuel gauges that read higher than the actual level, which can cause the engine to stall unexpectedly when the tank runs dry. A seatbelt buckle sensor may be improperly connected, preventing the front airbag from deploying in a crash. The final recall involves incorrect tire pressure and size information on the vehicle label, which can lead to improper tire inflation or fitment.
