The Vauxhall Crossland X (sold under the Opel brand in continental Europe) is a B-segment urban crossover. Launched in 2017 to replace the Meriva minivan, it is the result of the first technical partnership between General Motors (then owner of Opel/Vauxhall) and the PSA group, based on the PF1 platform (shared with the Peugeot 2008 I and the Citroën C3 Aircross). Although it offers excellent roominess and appreciable modularity (sliding rear bench), its reliability is heavily marred by the adoption of PSA engines from that era, notably the 1.5 diesels (camshaft chain problems) and the 1.2 petrols (wet belt). Overall reliability rating: Poor.
The Vauxhall/Opel Crossland X is a practical family vehicle, but its reliability record is weighed down by its PSA-sourced engines. If you absolutely want a diesel, favor the 2017-2018 models equipped with the older 1.6 Turbo D, which is generally more robust despite some quirks with the AdBlue system. The newer 1.5 Turbo D is to be avoided unless the seller can prove, with an invoice, that the camshaft chain kit has been replaced with the reinforced 8 mm version. The petrol versions are also to be avoided due to the wet belt scandal (PureTech).
