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

Reliability score : 6.8/10

The Opel Grandland X is a compact SUV launched in 2017, marking Opel's entry into the PSA Group (now Stellantis) fold. It shares its EMP2 platform with its cousins Peugeot 3008 and Citroën C5 Aircross, which gives it solid and proven technical foundations. Positioned as a family and versatile vehicle, it stands out with a more understated and classic design than its French counterparts, prioritizing comfort and ergonomics. The 'X' generation was produced until 2021, when it underwent a significant facelift and was simply renamed 'Grandland', dropping the 'X' suffix. Overall, the Grandland X offers a good compromise between interior space, ride comfort, and equipment. Its reliability is closely linked to that of the PSA powertrains it uses, with specific points of attention for some of them

⚠️ Weaknesses

Exterior design considered a bit bland by some
Interior materials sometimes inferior to some competitors
Reliability of the timing belt on the 1.2 PureTech
Complexity and potential problems of AdBlue systems on diesels
Reliability of hybrid (PHEV) versions still imperfect and costly in case of failure

🎯 Verdict

The Opel Grandland X is an honest and comfortable compact SUV, offering a more discreet alternative to the 3008 and C5 Aircross. For serene use, the 2.0 BlueHDi 180 and 1.6 PureTech 180 engines are the most recommendable, offering a good balance of performance/reliability. The 1.5 BlueHDi 130 is an excellent choice for high-mileage drivers, provided the AdBlue system is closely monitored. Regarding the hybrid versions (PHEV), our verdict is more nuanced. If the idea of very low consumption in the city and electric driving appeals to you, be aware of the technical complexity and potential costs in case of failure. These versions had a difficult start with software and management issues. NEGOTIATE strongly and ensure that all updates have been performed and that the service history is impeccable. An extended test drive is imperative to verify the proper functioning of the hybrid drivetrain and the absence of jerks. They are to be preferred if you have a home charging point and your daily commutes are predominantly electric. The 1.2 PureTech 130 should be considered with caution due to its wet timing belt. If you opt for this engine, ensure the belt has been preventively replaced or f
