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.
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.
On 2017-2018 Giulia sedans with the 2.0L turbo four (and 2018 Stelvio), an engine misfire can dump unburned fuel into the exhaust and overheat the catalytic converter. The excess heat can damage nearby engine-compartment wiring and components, which FCA identified as both an engi… Severity: high.
NHTSA lists 337,128 potentially affected vehicles under recall 24V510 across several models, including certain 2017–2024 Giulias. A disrupted buckle-switch connector can interfere with the restraint system's belt-status signal, so a front seat airbag may not perform as intended i… Repairs typically run $0-$0. Severity: high.
A batch of Giulias and Stelvios left the assembly plant with brake and clutch fluid contaminated by an incompatible mineral oil. The contamination can swell seals and degrade braking performance, in some cases producing system failure with little warning. NHTSA/Alfa identified ro… Severity: high.
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.
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.
Recall 19V-148 / V27 concerns certain 2017–2019 Giulia vehicles equipped with Adaptive Cruise Control, sales code NH3. During a specific wheel-slip event with ACC active, the Brake System Module can retain a positive torque request. Normal cancellation may fail and unexpected acc… Repairs typically run $0-$0. Severity: high.
Recall 24V-943 / E0B covers certain 2019–2020 Giulia vehicles built May 30, 2019–February 6, 2020. A loose pedal-to-booster rod connection can separate and cause loss of brake function.

The Giulia Q4 AWD system can develop two related transfer case symptoms with age: a perceptible jolt or slip during light-throttle acceleration in 2nd-3rd gear (output-shaft clutch wear) and a resonant low-frequency rumble at highway speed around 4th-5th gear (worn output bearing… Repairs typically run $300-$2,500. Severity: medium.
Owners frequently report the 12V battery draining when the car sits for several days, often traced to modules not sleeping properly, a faulty Intelligent Battery Sensor (IBS), or BCM-related charging logic. Symptoms include battery warning lights after 4-5 days of inactivity, sto… Repairs typically run $150-$600. Severity: medium.
US recall 19V551 / Alfa Romeo V84 covers selected 2018–2019 Giulia vehicles with affected BCM software. The filing identifies 11,148 Giulias built April 5, 2018–May 29, 2019.
