Vauxhall Insignia I (G09) (2008 – 2017)

Reliability score : 5.8/10

The first-generation Vauxhall/Opel Insignia (G09) marked a radical break from the Vectra it replaced. Voted European Car of the Year in 2009, it appealed with its fluid design, highway comfort, and technological equipment (AFL headlights, FlexRide suspension). However, its high weight (often over 1.6 tons) penalized its performance and fuel consumption. A major facelift occurred in late 2013, correcting the ergonomics of the center console (too many buttons), improving the infotainment system (IntelliLink), and introducing new engines. Although this sheet focuses on diesel engines (highly popular on this model), the Insignia had a global career under different badges (Buick Regal, Holden Insignia), justifying a wide variety of engines.

✅ Strengths

Exceptional ride comfort on the highway
Very meticulous soundproofing (especially after the 2013 facelift)
Exterior design that has aged very well
Generous trunk volume (Hatchback and Sports Tourer/Estate versions)
Unbeatable price/equipment ratio on the used market
Excellent AGR-certified ergonomic seats (optional or on high trims)

⚠️ Weaknesses

Excessive weight penalizing driving dynamics, fuel consumption, and brake/tire wear
Fatal design flaw on the 2.0 CDTi (oil pickup seal)
Very fragile M32 manual gearbox on smaller engines
Mediocre rear visibility (reversing camera almost essential)
Catastrophic center console ergonomics before 2013 (too many buttons)
Disappointing rear seat space given the exterior dimensions (headroom)

🎯 Verdict

The first-generation Insignia is an excellent cruiser, sold at bargain prices on the used market. However, buying a pre-2014 2.0 CDTi diesel is akin to Russian roulette because of the infamous oil pump pickup seal. If you opt for this engine, demand a recent invoice for the replacement of this seal, or plan a budget of 300 to 500 € to have it done immediately after purchase. The best diesel choice is the post-2014 2.0 CDTi 170 hp (B20DTH), freed from this problem and coupled with a modernized interior. Avoid the 1.6 CDTi because of its poorly placed timing chain. In petrol, the 1.4 Turbo is a good economical choice if the gearbox has been overhauled.
