Opel Grandland X (2017–2021) (2017 – 2021)

Reliability score : 6.2/10

The Opel Grandland X (which became simply 'Grandland' after its facelift in late 2021) marks Opel's renewal under the PSA era (now Stellantis). Based on the excellent EMP2 platform, it is the direct technical cousin of the Peugeot 3008 II and Citroën C5 Aircross. It stands out with a more conservative design, Germanic ergonomics (retaining physical controls for climate control), and very comfortable AGR-certified seats. While its road handling is imperial, its overall reliability is heavily conditioned by the PSA-sourced engines it uses. Engine choice is absolutely crucial for this model.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The Opel Grandland X is a family SUV packed with objective qualities: it is comfortable, spacious, and very pleasant to drive. Unfortunately, its record is tarnished by the design flaws of this generation's PSA engines. If you are looking for a Diesel, avoid the 1.5 (130 hp) unless the chain modification (8.4 mm) has been done and invoiced. The 1.6 Diesel (120 hp) is a reasonable choice, but the 2.0 Diesel (177 hp) is by far the best engine in the range: robust, torquey, and reliable. For petrol, the 1.2 Turbo is to be avoided. Buy this vehicle only with full awareness and an impeccable service history.
