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.

This issue also affects: Alfa Romeo Stelvio, Chrysler 300, Chrysler Aspen

Common Symptoms

  • Engine stalls while driving
  • No-start condition
  • Multiple warning lights
  • Loss of electrical power

How to Fix

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.

Typical repair cost:$200 - $2,000

On the 2020-2025 Alfa Romeo Giulia, a printed-circuit-board defect and software-stability fault in the Marelli-supplied infotainment/radio unit can cause the rearview camera to display a blank, black, blue, or inverted image when reverse is selected, reducing rear visibility. This led to NHTSA recall 25V667 covering 62,910 Giulia and Stelvio vehicles. Owners also report the infotainment screen freezing or scrambling more generally.

Common Symptoms

  • Blank, black, blue, or inverted rearview camera image
  • Backup camera unavailable message
  • Infotainment screen freezing or scrambling
  • Display reboots on its own

How to Fix

Under recall 25V667, dealers inspect and replace the radio/head unit as necessary and update the rearview-camera software, free of charge. For general freezes, owners report a long-press on the volume knob can reboot the unit; vehicles built after March 2025 already have the updated hardware/software.

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.

This issue also affects: Alfa Romeo Stelvio, Chrysler Town & Country, Fiat 500X

Common Symptoms

  • Coolant loss without visible puddle
  • Sweet smell from engine bay
  • Low coolant warning
  • Steam from turbo area

How to Fix

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.

Typical repair cost:$300 - $800

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.

This issue also affects: Alfa Romeo Stelvio, Jeep Wrangler, Porsche Macan

Common Symptoms

  • Whining during turns
  • Grinding noise during acceleration
  • Vibration from center tunnel
  • AWD warning light

How to Fix

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 2017-2026 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.

This issue also affects: Alfa Romeo Stelvio, Jeep Wrangler, Porsche Macan

Common Symptoms

  • Squealing during light braking
  • Excessive black brake dust on wheels
  • Grinding noise when cold
  • Vibration during braking

How to Fix

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.
