Alfa Romeo 147 I phase 2 (937) (2004 – 2010)

Reliability score : 6.8/10

The Alfa Romeo 147 Phase 2 (Type 937) was introduced in late 2004 with a facelift designed by Giorgetto Giugiaro. It features a more aggressive front end (slimmer headlights, enlarged grille), redesigned taillights, and improvements to the suspension for better comfort. While it retains its exceptional chassis (double wishbone front suspension) which makes it one of the most dynamic compact cars of its era, it also inherits the chronic weaknesses of Phase 1 (rapid wear of running gear, capricious electronics). The JTD diesel engines evolved into JTDm (Multijet), offering excellent performance, while the Twin Spark (TS) petrol engines remain fuel-thirsty and demanding in terms of maintenance. The introduction of the Torsen mechanical limited-slip differential (Q2 versions) in 2006 was a maj

✅ Strengths

Exceptional road handling (incisive front axle, very direct steering at 2.2 turns lock-to-lock).
Timeless design, especially in Phase 2 with the aggressive front end.
Very powerful and generally very durable JTDm diesel engines.
Warm interior presentation and driver-oriented gauges.
Q2 versions (Torsen differential) offering formidable traction.

⚠️ Weaknesses

Extremely fragile running gear (upper and lower wishbones often need replacement).
Catastrophic turning radius (difficult city maneuvers).
Twin Spark petrol engines demanding in maintenance and thirsty for fuel/oil.
Selespeed automated gearbox is slow, brutal, and a source of costly breakdowns.
Whimsical electronics (airbag warning lights, ODB error messages).
Interior plastics that become sticky over time (a common issue of the 2000s).

🎯 Verdict

The Alfa Romeo 147 Phase 2 is a 'love at first sight' compact car that should be bought with full awareness. It offers driving pleasure and communicative steering that its German or French competitors struggle to match. However, this dynamism comes at a high price: the running gear components are consumables, and maintenance tolerates no negligence. The sensible choice: A 1.9 JTDm 8V 120 hp, indestructible and economical. The passionate choice: A 1.9 JTDm 16V 150/170 hp in Q2 version (provided the intake swirl flaps are deleted) or a 1.6 TS 120 hp for low-mileage drivers, provided there is a clear timing belt history. To avoid: Versions equipped with the Selespeed gearbox and models without a service book.
