Known Issues, Recalls, and Technical Service Bulletins (TSBs)

A significant issue affects the fuel pump on these vehicles, leading to a major safety recall. Many owners 🎬 Watch: Learn more about the investigation into these fuel pump issues. have experienced sudden and unexpected engine stalling while driving.

Recall 93C: Sudden Fuel Pump Failure

Stellantis (Alfa Romeo's parent company) issued a recall for approximately 54,000 Giulia and Stelvio vehicles, including 2017-2019 Giulia models with both the 2.9L V6 and 2.0L engines. The recall, identified by NHTSA, addresses a defect where the low-pressure fuel pump can fail without warning.

The root cause is believed to be components within the pump that are sensitive to heat, which can cause them to warp and stop fuel flow. This results in fuel starvation and a sudden loss of power, often while driving at speeds over 25 mph. In many cases, the vehicle cannot be restarted after it stalls. As of late 2025, the manufacturer was still developing a permanent remedy for this issue.

TSB 18-001-18: Low Fuel System Pressure

Prior to the recall, Alfa Romeo released Technical Service Bulletin #18-001-18 for 2017-2018 Giulia models built on or before August 30, 2017. This bulletin was created to address customer complaints of an illuminated Malfunction Indicator Lamp (MIL) and the diagnostic trouble code P008A-00 - Low Pressure Fuel System Pressure - Too Low. The prescribed fix was to inspect and, if necessary, replace the fuel pump module.

Symptoms of a Failing Fuel Pump

A failing fuel pump on the Giulia Quadrifoglio often provides little to no warning before a critical failure. Key symptoms include:

• Sudden Engine Stall: The most reported and dangerous symptom is the engine completely shutting off while driving.
• Warning Lights: Multiple warnings may appear on the dashboard simultaneously, such as "Service Engine," "Service Electronic Throttle Control," and "Start/Stop Unavailable."
• Failure to Restart: After stalling, the engine will typically crank but will not start, or it may start for a few seconds and then die again.
• Hesitation Under Acceleration: Some owners notice a loss of power or fuel pressure drop specifically during hard acceleration at higher RPMs.
• Check Engine Light with Code P0087 / P008A: If the pump is failing but has not died completely, it will often trigger a check engine light with a code for low fuel system pressure.

Buying a Used Fuel Pump: What to Check

For a high-performance vehicle like the Quadrifoglio, a quality used OEM fuel pump is often a better choice than a questionable aftermarket part. Here’s what to inspect before buying a recycled unit:

• Verify the Part Number: The most important step. Ensure the part number matches your original pump. Common numbers for the 2.9L V6 are 00505688900 or 505474790. Do not purchase a pump intended for the 2.0L engine.
• Inspect the Electrical Connector: Check the plastic connector and pins on top of the pump assembly. Look for any signs of melting, discoloration, or charring. This can indicate an overheating pump or a poor electrical connection, which is a major red flag.
• Check the Fuel Level Sender: The fuel level sender is the arm and float attached to the pump assembly. Make sure the arm moves freely and is not bent or damaged. A damaged sender will cause an inaccurate fuel gauge reading.
• Ask About Mileage: While even low-mileage pumps from 2017-2019 could be part of the defective batch, choosing a lower-mileage unit from a later model year (2020+) may increase your chances of getting a more reliable part. Used pumps can be found with mileage as low as 20,000-45,000 miles.
• Condition of the Strainer: Look at the fuel strainer (the mesh sock at the bottom). It should be relatively clean. A heavily contaminated or dark, sludgy strainer suggests the pump came from a vehicle with a very dirty fuel tank, which can shorten the pump's life.

Replacement Cost Breakdown

The cost to replace the fuel pump can vary based on location and whether you choose a new or used part. Due to the recall, a dealer may perform this work for free on affected 2017-2019 models once a final remedy is available.

Replacement Overview & Difficulty

Replacing the in-tank fuel pump on a Giulia is a moderately difficult job, primarily because it involves working with the fuel system and requires a specific electronic procedure after installation.

• Difficulty Rating: 4 out of 5
• DIY Feasible: Not recommended for beginners.
• Procedure Summary: The technician will first relieve pressure from the fuel system and disconnect the battery. Access to the pump is typically under the rear seat cushion via a metal access cover. The fuel lines and electrical connector are disconnected, and a large retaining ring is unscrewed to remove the pump assembly from the tank.
• Special Tools Required: A professional scan tool is needed after installation. According to Alfa Romeo's service information, a "Fuel Supply System Components Replacement" procedure must be performed, followed by a reset of the "Self-Adaptive Parameters." Skipping this step can result in incorrect fuel delivery or persistent error codes.
