What is the 2017-2026 Alfa Romeo Giulia Low-Pressure Fuel Pump Failure Causing Stall (Recall 25V-586)?
2017+ Giulias can experience sudden engine stall or no-start due to a defective low-pressure fuel pump inside the fuel delivery module. The pump's internal commutator wears prematurely and loses contact, cutting fuel supply at any speed. NHTSA recall 25V-586 (Stellantis campaign… Repairs typically run $200-$2,000. Severity: high.
What is the 2017-2026 Alfa Romeo Giulia Turbo Coolant Line Leak?
The turbocharger coolant supply and return lines develop leaks at the crimped fittings, causing coolant loss and potential overheating. The plastic quick-connect fittings become brittle from heat cycling. Repairs typically run $300-$800. Severity: high.
What is the 2017-2022 Alfa Romeo Giulia Electrical Faults from Water Intrusion / BCM Failure?
Water enters the cowl/firewall area (failed bulkhead gasket, detached fresh-air vent, or clogged A/C evaporator drain) and drips onto the Body Control Module and wiring loom in the passenger footwell. The resulting corrosion and shorts cause wide-ranging, intermittent electrical… Repairs typically run $300-$1,500. Severity: high.
What is the 2017-2019 Alfa Romeo Giulia Low-Pressure Fuel Pump Failure (Sudden Power Loss)?
The in-tank low-pressure fuel pump assembly can warp/degrade from underhood and operating heat, reducing or stopping fuel flow to the engine. This causes engine fuel starvation, leading to stalling or a sudden loss of motive power (LOMP) while driving, often without warning. NHTS… Repairs typically run $700-$1,400. Severity: high.
What is the 2017-2019 Alfa Romeo Giulia Timing Chain Rattle / Oil Pump Bolt Loosening (2.0T)?
On the 2.0L turbo four-cylinder, owners report a metallic rattle at cold/hot start, attributed to the timing chain tensioner waiting for oil pressure or, in some cases, a loose wastegate actuator. More seriously, early 2017-2018 engines had an oil pump mounting bolt that could lo… Repairs typically run $800-$3,000. Severity: high.
What is the 2017-2026 Alfa Romeo Giulia Infotainment System Random Reboots?

Dealers report seein… Repairs typically run $150-$800. Severity: medium.
What is the 2017-2026 Alfa Romeo Giulia Front Brake Squeal and Dust?
The front brakes produce excessive squeal during light braking and generate heavy brake dust. The aggressive OEM pad compound prioritizes stopping power over noise and dust characteristics. Repairs typically run $150-$500. Severity: low.
What is the 2017-2021 Alfa Romeo Giulia Jerky / Hunting Transmission at Low Speed (ZF 8-Speed)?
The ZF 8-speed automatic, combined with throttle-by-wire and brake-by-wire, can shift harshly or hunt between gears (commonly around 3rd-4th) at low speed and light throttle, and jerk when transitioning off the auto stop-start neutral state. The behavior is exaggerated in Dynamic… Severity: low.
