Alfa Romeo 159

Production Years: 2005 - 20114 Documented Faults

The Alfa Romeo 159 is widely celebrated as one of the most beautiful saloons of its era, marking a significant step forward in build quality and structural integrity compared to its predecessors. Designed to compete with German rivals, it offers a refined and planted driving experience, though it remains a heavier, more substantial vehicle that requires a nuanced understanding of its specific mechanical requirements for long-term UK ownership. While robust in construction, the 159 is not without its vulnerabilities, particularly regarding the effects of the British climate on its underside. The front subframe, if not protected, is highly susceptible to structural corrosion, and it is a critical maintenance point that demands inspection. Furthermore, prospective owners should be mindful of the different gearboxes fitted to the range; while the 2.4 and 2.0 diesels and the 3.2 V6 enjoy the robust F40 transmission, the M32 unit used in some models requires particular care to avoid bearing failure. For the dedicated enthusiast, the 159 rewards with genuine Alfa character and a comfortable, well-appointed cabin. The key to successful ownership is proactive maintenance—specifically targeting subframe protection, ensuring the correct green power steering fluid is utilised, and adhering to strict cambelt and oil change intervals. When sourced as an "enthusiast-maintained" example with a verified history, the 159 remains a stunning, reliable, and deeply desirable modern classic.

Common Faults & Reliability

These are the most common documented problems for the Alfa Romeo 159, sorted by their typical impact and frequency.

Front Subframe Corrosion

high severity

The front subframes were poorly protected from the factory and are prone to severe rusting in the UK climate. Replacing one is expensive due to parts and labor.

Est. repair cost:£800–£1,500

M32 Gearbox Bearing Failure

high severity

The M32 6-speed gearbox used in 1.9 diesels and 2.2 petrols has weak bearings that fail over time, especially if the oil is not changed.

Est. repair cost:£600–£1,200

Power Steering Rack Failure

high severity

Early cars used red steering fluid which damaged the rack seals. Many have been converted to green fluid, but the damage may already be done.

Est. repair cost:£500–£900
