Engine/EmissionsHigh severity💬 Owner reports
Failed timing belts on the 1.9 CDTi, often due to a seized water pump which is driven by the belt.

Where this Vauxhall Vectra fault data comes from
If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Vauxhall Vectra owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Vauxhall Vectra goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
