8 Common Alfa Romeo Giulia Engine Failures & Solutions

The Alfa Romeo Giulia is a sleek, stylish Italian car with powerful engines and impressive driving dynamics.

Despite its many desirable features, the Alfa Romeo Giulia has struggled with reliability concerns since its launch in 2016.

While some owners have enjoyed their cars without issue, others have reported engine failures that can cost thousands of dollars to repair.

In this article, we will take a closer look at the reported Alfa Romeo Giulia engine failure and examine potential causes. Let’s scroll down!

8 Common Alfa Romeo Giulia Engine Failure

Users can experience many major issues with the engine, such as electrical problems, malfunctioned rear brake discs, fuel leaks, loss of ABS, contaminated brake fluid, engine misfires, cruise control, and broken fuel gauge.

These problems can explain why Alfa Romeo not popular.

Electrical Problems

Most complaints in used Alfa Giulia review forums mention its electrical designs. Many have reported various symptoms.

For instance, always-on reverse lights drain the car battery, the start-stop system fails too often, and the vehicle shuts down without illuminating any check engine lights.

In other circumstances, bad wiring may be the source of the issue (which can explain the car’s exterior lights staying on although your vehicle is shut off).

Failing Rear Brake Discs

Rear brake discs are a type of braking system located on a vehicle’s rear wheels. They work in conjunction with the front brake discs to slow down and stop the vehicle.

Several Alfa Romeo Giulia buyers reported an abrupt shortage in braking power that resulted in hazardous situations.

It was eventually discovered that the 2020 Giulia’s rear brake discs were susceptible to breaking.

At the 2020 end, Alfa Romeo issued recall number 20V714000, and the brake pads and discs were changed for free

Fuel Or Oil Leaks And Fire Risk

Fuel leaks are one of the most-mentioned Alfa Romeo Stelvio problems. A car with fuel leaks can be a serious safety hazard and should be addressed immediately.

Fuel leaks can occur for various reasons, including a damaged fuel tank or fuel lines, loose connections, or faulty fuel injectors.

A fracture in the fuel line sensor housing caused this usual issue. Fuel would seep from the fuel lines, increasing the fire risk.

Upon the discovery of the flaw, Alfa Romeo’s manufacturer offered free engine replacement for all impacted Giulia cars.

ABS Loss

ABS stands for Anti-lock Braking System, a safety feature in modern vehicles that helps prevent the wheels from locking up during emergency or hard braking.

In fact, there was a serious recall involving Giulia cars manufactured between 2020 and 2021 due to a mechanical fault.

Harsh braking could lead to a bad ABS module and the HCU rotor separating, resulting in reduced brake power and ABS loss.

Car owners were informed of this issue in June 2021, and the part was replaced at no cost.

Contaminated Brake Fluid

Polluted Brake Fluid

First, some 2017 – 2018 Giulias armed with a GME 280 horsepower engine and AWD were recalled.

The brake fluid line may come into touch with a hose clamp of the coolant and break, allowing fluid to leak in the exhaust. And owners have to flush the brake fluid more often.

The recall, 18V828000, was requested in late 2018.

Some vehicles produced in early 2018 were also recalled in 2017 due to the possibility of harmful substances.

The recall was proceeded under reference number 17V823000. The manufacturer resolved both issues for free.

Engine Misfires

The 2017 and 2018 models of the Alfa Romeo Gulia were recalled due to an engine misfiring issue.

This problem affected the 2.0-liter turbocharged versions and, if not addressed, might lead to more serious failures.

Misfires can overheat the catalytic converter, damage engine wiring, and cause other electrical failures.

Worst-case circumstances might include engine fires and malfunctioning exhaust systems.

Cruise Control

Another issue concerned Giulia owners from 2017 to 2019. In some cases, they could not turn off the smart cruise control.

This problem resulted from incorrect module software in the brake system, which prevented this from happening when traction control sensed a wheel slip.

In 2019, there was a recall numbered 19V148000 to fix the software for free.

Wrong Fuel Gauge

A fuel gauge is an instrument located on a vehicle’s dashboard that displays the fuel amount in the gas tank.

The fuel gauge typically consists of a needle that moves across a range of markings or numbers to indicate the fuel remaining in the tank.

A defective Body Control Module (BCM) of the 2018 – 2019 Giulias caused the fuel gauge to show a larger gasoline level than what was in the tank.

As a result, people ran out of gas before they believed they had to replenish. The manufacturer decided to recall these faulty cars (number 19V551000), and the BCM was upgraded at no cost.

So how many miles can a Alfa Romeo Giulia last? You can expect to drive 521 miles with a full tank.

Yes. According to many Alfa Romeo Giulia reviews, it earns a 4.7/5 star rating.

However, the Alfa Romeo Giulia 2.2 reliability has received mixed reviews.

While some owners report having a positive ownership experience with few issues, others have reported various problems and maintenance issues.

It’s important to note that reliability ratings can vary depending on the model year and specific trim level.

Some newer Giulia models have reportedly seen improvements in reliability, while older models may have had more issues.

Overall, it is often praised for its driving dynamics, stylish design, and powerful engines.

Buyers should research and carefully consider their priorities before deciding if the Alfa Romeo Giulia is the right car for them.


While the Alfa Romeo Giulia is a car that impresses with its sleek design and powerful engines, it’s clear that engine failure is a significant issue for some owners.

Whether it’s caused by poor manufacturing, design flaws, or other factors, Alfa Romeo Giulia engine failure can be a frustrating and expensive problem to address.

While Giulia offers many desirable features, it’s important to consider the long-term costs and potential headaches that can come with these issues.

Thus, buyers should carefully check the car’s reliability record and weigh the potential risks before purchasing.
