Problematic

Reliability, common problems and owner reviews for the Opel Vectra C 2.2 direct (Z22YH). Check this before you buy used.

The 2.2 direct-injection (Z22YH) gives the Vectra useful pace, but it's the petrol to be wary of: it's well known for timing-chain stretch (rattle, then misfire/poor running, and engine damage if it jumps), plus direct-injection carbon and the odd injector. The chain job is involved. A car with a documented recent chain and quiet cold-start can be fine, but an unknown-history one is a gamble — the 1.8 is the safer petrol if you don't need the performance.
