On the 2017-2026 Alfa Romeo Giulia, 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 93C) covers free replacement. Symptoms include stalling at idle, no-start hot, and intermittent fuel pump prime noise from the rear of the vehicle. Failures cluster at 30,000-80,000 miles.
Have the ECM and wiring harness inspected at an Alfa Romeo dealer. FCA has issued TSB 18-024-17 REV.A addressing the wiring harness routing. ECM replacement with updated software may be required.

On the 2017-2022 Alfa Romeo Giulia, 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 failures. Owners have reported headlights, brake lights, turn signals, and driver-assist systems all cutting out at speed, plus dead batteries and warning-light storms.
Fix the water-intrusion source first (reseal bulkhead gasket, reattach fresh-air vent, clear the A/C drain) before replacing electronics. A water-damaged BCM must be replaced and re-programmed with a proxy alignment (not plug-and-play); used modules often require harness re-pinning. Dry and inspect the footwell wiring loom.

On the 2017-2026 Alfa Romeo Giulia, the Uconnect infotainment system reboots randomly during driving, losing navigation, audio, and phone connectivity. The system can take 30-60 seconds to restart, leaving the driver without backup camera or climate controls.
Update the Uconnect software to the latest version. Perform a factory reset if issues persist. Some units require hardware replacement of the head unit.

On the 2017-2021 Alfa Romeo Giulia, 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, stop-start system failures, and corroded/leaking batteries. Measured parasitic draw stays elevated (250mA+) instead of dropping to a low sleep current.
Replace a faulty Intelligent Battery Sensor (IBS) with the revised part, which has resolved intermittent drain for many owners. Address any BCM water damage and apply available software updates to correct charging/sleep logic; verify with a parasitic-draw test and replace the battery if internally damaged.

On the 2017-2018 Alfa Romeo Giulia, 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 roughly 307 affected vehicles built in a specific window.
Common Symptoms
Decreased braking performance
Soft or spongy brake pedal
Brake warning light
Reduced clutch feel
How to Fix
Under the recall, dealers inspect the braking system and replace the affected brake/clutch fluid and components as necessary, free of charge. Out of warranty, a full brake fluid flush with the correct DOT-spec fluid and seal inspection is the remedy.
On the 2017-2026 Alfa Romeo Giulia, 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.
Replace the OEM brake pads with a ceramic compound alternative for reduced noise and dust. Clean and lubricate the caliper slide pins and apply anti-squeal shims. The Quadrifoglio Brembo calipers need specific QV pads.

On the 2017-2026 Alfa Romeo Giulia 2.0L Turbo I4, 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.
Replace the turbo coolant lines with updated Mopar parts that use improved fittings. Check the coolant level and top off with the correct FCA MS-90032 coolant. Pressure test the system after repair.

On the 2017-2019 Alfa Romeo Giulia, 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. NHTSA opened preliminary evaluation PE24-003 and the issue escalated to a full recall (25V586) covering roughly 53,849 Giulia and Stelvio vehicles; Stellantis acknowledged 437+ North American complaints and five crashes in Europe.
Under recall 25V586, dealers replace the fuel delivery module (fuel pump assembly) free of charge. Owners experiencing stalling, hard starts, or P0087 low fuel rail pressure codes should have the fuel pump tested for pressure dropout and replaced. Out of warranty, fuel pump module replacement typically runs in the listed range.
On the 2017-2019 Alfa Romeo Giulia, 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 loosen, dropping oil pressure and accelerating chain/actuator wear; some owners found metal particles in the oil. Alfa updated the oil pump on 2019/2020+ engines.
Diagnose the rattle source: tighten/replace the wastegate actuator if loose, or replace the timing chain assembly and camshaft actuators (variable valve timing solenoids) if the chain has stretched. For affected early engines, inspect/re-torque or replace the oil pump with the updated part. Maintain shorter oil-change intervals (around 6,000 miles) with correct-spec oil.

On the 2017-2026 Alfa Romeo Giulia 2.0L Turbo I4, 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 bearings). Both are exacerbated by infrequent transfer-case fluid changes. The original 'whining during low-speed turns' description was incorrect — that pattern matches differential wear, not the Q4 transfer case.
Drain and refill the transfer case with the correct Alfa Romeo-specified fluid. If noise persists, the transfer case clutch pack assembly needs replacement. FCA extended warranty coverage for some VINs.

On the 2017-2022 Alfa Romeo Giulia, beyond its electrical consequences, the Giulia has a recurring water-leak problem where rain or car-wash water enters via the cowl under the windshield, a failed firewall/bulkhead seal, or a clogged A/C evaporator drain, soaking the passenger footwell carpet. Dealers report seeing the detached fresh-air vent and bulkhead leak repeatedly. Standing water promotes mold, odor, and downstream electronics corrosion.
Common Symptoms
Wet passenger or driver footwell carpet
Water dripping from under the dash
Musty/mold odor in cabin
Foggy windows
Leaks after rain or car wash
How to Fix
Identify the source: reseal the bulkhead gasket, reattach the fresh-air inlet vent, clear or extend the A/C evaporator drain tube, and confirm cowl drains are unobstructed. Dry the carpet and underlayment thoroughly and inspect any footwell electronics for water damage.

On the 2017-2021 Alfa Romeo Giulia, 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 (D) mode where shift mapping is intentionally aggressive, and worsens when the powertrain is cold.
Common Symptoms
Jerking back and forth at low speed
Harsh shifts in Dynamic mode
Gear hunting at light throttle
Hesitation pulling away from stop
How to Fix
Have the dealer open a case to apply ECM/TCM software updates and reprogramming, which smooths shift quality for many owners. As a workaround, disable auto stop-start and use Normal/All-Weather modes for low-speed driving; ensure the car is fully warmed up. Verify transmission fluid level/condition if symptoms persist.
