The Alfa Romeo 159. Just the name evokes images of Italian flair, sporting prowess, and a certain je ne sais quoi that sets it apart from its more… sensible competitors. But beauty, as they say, is only skin deep. And when it comes to buying a used car, especially one as potentially temperamental as an Alfa, reliability is paramount. So, is the 159 a ticking time bomb waiting to drain your wallet, or a surprisingly robust classic in the making? Let's delve into the build quality and reliability of this stylish sedan and wagon to help you make an informed decision.

The Alfa Romeo 159: More Than Just a Pretty Face?

The 159, produced from 2005 to 2011, replaced the venerable 156 and aimed to elevate Alfa Romeo into a more premium segment. Based on the GM/Fiat Premium platform, it was a significant step up in terms of build quality and materials compared to its predecessor. But did that translate into improved reliability? That's the million-dollar question.

Under the Skin: Examining the Platform and Components

The shared platform with some GM vehicles (like the Saab 9-3) is often seen as a mixed blessing. On one hand, it meant access to proven engineering and components. On the other, it meant some of the "Alfa-ness" might have been diluted. However, the platform itself is generally considered robust.

Key areas to consider regarding build quality and reliability:

  • Engines: The engine range was diverse, including petrol and diesel options. Some engines are more reliable than others.
  • Suspension: The 159 boasts a sophisticated multi-link suspension setup, contributing to its excellent handling.
  • Electronics: Alfa Romeos, historically, have had a reputation for electrical gremlins.
  • Bodywork: Rust can be a concern, especially on older models.
  • Interior: Interior quality varies depending on trim level, but overall, it's a decent place to be.

Engine Choices: Separating the Wheat from the Chaff

The 159 offered a wide range of engines, each with its own quirks and potential problems. Understanding these differences is crucial for assessing overall reliability.

  • Petrol Engines:
    • 1.8 MPI (140 bhp): This engine, while relatively simple, is often considered underpowered for the 159's weight. It's generally reliable, but performance is lacking.
    • 1.9 JTS (160 bhp): The JTS engines (Jet Thrust Stoichiometric) are direct-injection units. These can suffer from carbon buildup on the intake valves, leading to reduced performance and misfires. Regular servicing and preventative maintenance are essential.
    • 2.2 JTS (185 bhp): Similar to the 1.9 JTS, the 2.2 JTS can also experience carbon buildup issues. It offers slightly better performance but shares the same potential drawbacks.
    • 3.2 JTS V6 (260 bhp): This engine, sourced from Holden (GM), is generally considered the most reliable petrol option. It's a robust unit with a good power delivery. However, it's also the thirstiest.
  • Diesel Engines:
    • 1.9 JTDm (120, 150 bhp): The JTDm (Jet Thrust Direct injection Multijet) diesel engines are generally reliable, but they can suffer from issues common to modern diesels, such as EGR valve problems, DPF (Diesel Particulate Filter) blockages, and swirl flap failures (on earlier models).
    • 2.0 JTDm (136, 170 bhp): An evolution of the 1.9 JTDm, this engine offers improved performance and efficiency. It shares similar potential issues with the 1.9 JTDm, including EGR, DPF, and swirl flap concerns.
    • 2.4 JTDm (200, 210 bhp): This five-cylinder diesel offers strong performance and a distinctive sound. While generally reliable, it can be prone to issues with the EGR valve, DPF, and turbocharger.

Which engine is the most reliable? The 3.2 JTS V6 is generally considered the most robust petrol option. The 1.9 JTDm (particularly the later versions) and 2.0 JTDm are generally reliable diesels, provided they are well-maintained.

Suspension and Handling: A Double-Edged Sword

The Alfa Romeo 159 is renowned for its excellent handling, thanks to its sophisticated multi-link suspension system. However, this complexity can also lead to increased maintenance costs.

  • Bushings: The suspension bushings are a common wear item, especially on older models. Worn bushings can lead to vague handling, knocking noises, and uneven tire wear.
  • Wishbones: The upper wishbones are particularly prone to wear and may need replacing.
  • Shock Absorbers: The shock absorbers can also wear out over time, affecting ride quality and handling.

While the suspension contributes to the 159's engaging driving experience, be prepared for potential maintenance costs associated with its complexity.

Electrical Gremlins: Addressing the Alfa Romeo Stereotype

Alfa Romeos have historically been associated with electrical problems. While the 159 is a significant improvement over its predecessors, some electrical issues can still arise.

  • Dashboard Warning Lights: Erratic warning lights can be a common issue, often caused by faulty sensors or wiring.
  • Central Locking: Problems with the central locking system are not uncommon.
  • Window Regulators: The electric window regulators can sometimes fail.
  • Battery Drain: Some owners have reported issues with battery drain, potentially caused by faulty components or wiring.

While not all 159s suffer from electrical problems, it's wise to be aware of these potential issues and to check the car thoroughly before buying.

Bodywork and Rust: Spotting Potential Problems

The 159's bodywork is generally well-built, but rust can still be a concern, especially on older models or cars that have been exposed to harsh weather conditions.

  • Sills: The sills are a common area for rust to develop.
  • Wheel Arches: Check the wheel arches for signs of corrosion.
  • Underbody: Inspect the underbody for rust, especially around suspension mounting points.

Regular washing and waxing can help protect the bodywork from rust.

Interior Quality: A Comfortable and Stylish Cabin

The 159's interior is generally a pleasant place to be, with a stylish design and decent quality materials. However, some areas are more prone to wear and tear than others.

  • Leather Seats: The leather seats can wear over time, especially on the driver's seat.
  • Dashboard Trim: Some of the dashboard trim pieces can become loose or rattle.
  • Switchgear: The switchgear is generally robust, but some buttons can become worn or sticky.

Overall, the 159's interior is a comfortable and stylish environment, but be prepared for some potential wear and tear, especially on higher-mileage examples.

Common Issues and How to Avoid Them

To help you avoid potential problems, here's a summary of common issues and how to mitigate them:

  • Carbon Buildup (JTS Engines): Use high-quality fuel, consider using fuel additives, and ensure regular servicing.
  • EGR/DPF Problems (Diesel Engines): Regular servicing, occasional longer journeys to allow the DPF to regenerate, and consider using a DPF cleaner.
  • Suspension Wear: Regular inspections and replacement of worn bushings and wishbones.
  • Electrical Issues: Thoroughly check all electrical components before buying, and address any issues promptly.
  • Rust: Regular washing and waxing, and address any rust spots as soon as they appear.

The Importance of Proper Maintenance

As with any car, regular maintenance is crucial for ensuring the reliability of an Alfa Romeo 159. Adhering to the manufacturer's recommended service schedule, using high-quality parts, and addressing any issues promptly can significantly extend the life of the car.

Key maintenance points:

  • Regular Oil Changes: Use the correct oil and change it at the recommended intervals.
  • Timing Belt Replacement: The timing belt is a critical component, and failure can cause catastrophic engine damage. Replace it at the recommended interval.
  • Coolant Flush: Regularly flush the coolant to prevent corrosion and overheating.
  • Brake Fluid Change: Brake fluid absorbs moisture over time, which can reduce braking performance. Change it at the recommended interval.

Finding a Good Example: What to Look For

When buying a used Alfa Romeo 159, it's essential to find a well-maintained example. Here are some tips:

  • Service History: Look for a car with a complete and up-to-date service history.
  • Inspection: Have the car inspected by a qualified mechanic before buying.
  • Test Drive: Take the car for a thorough test drive to check for any issues.
  • Check for Rust: Carefully inspect the bodywork for signs of rust.
  • Electrical Components: Test all electrical components to ensure they are working correctly.
  • Listen for Noises: Listen for any unusual noises from the engine, suspension, or transmission.
