Vauxhall model reference
Vauxhall Insignia
What our record holds on the Insignia, sold in the UK 2008 to 2022: body styles, fuel types and the road tax a used one pays.
No reliability figure is published for the Vauxhall Insignia that this site could cite. What circulates instead is survey data from panels that select themselves, and warranty claim rates published by companies with something to sell.
Any percentage would be our own calculation. Which years count, and whether a facelift and a new generation sharing the Insignia name are one model or two, both move the answer, and neither choice is anybody official's.
So the field does not exist. We do not average the other Vauxhall models into a number and put it here, and we do not push a marque figure down onto the Insignia. What is real and specific is the paperwork for one car.
No fault ordering is published for the Insignia
A 2014 2.0 CDTi at about 129 g/km is a band D car, £170 a year in 2026/27. Fleet Insignias were often the 1.6 CDTi ecoFLEX, which came in lower.
That figure is a worked example for the year and engine named, not a rate for every Insignia. Read the CO2 figure and the first registration date off the V5C before you budget, because both change the answer.

Buying a used Insignia: what the record settles
Our record puts the Insignia's UK sales period at 2008 to 2022. That range is the useful starting point, because everything about the cost of running one turns on where a particular example sits inside it. It came in 3 body styles here, hatchback, estate and saloon, with 2 fuel types: petrol and diesel.
The Insignia was on sale on both sides of the road tax change of 1 April 2017, and that is the single most useful thing to know before you buy one. An example first registered up to 31 March 2017 is taxed on its CO2 figure under the lettered bands, so engine, gearbox and even wheel size can move two cars of the same year into different bands. One registered from 1 April 2017 pays the flat standard rate instead and its CO2 stops mattering. Two otherwise identical cars a year apart can cost noticeably different amounts to keep taxed, and only the V5C tells you which one you are looking at.
For running costs the fuel matters more than the badge. On the diesels the emissions section is where a neglected car loses its certificate: the particulate filter is inspected and the smoke reading is measured against a limit, and a filter that has never had a long run to clear itself will not pass on a good intention.
None of that is a substitute for the record of the actual car. The invoices name what was replaced, when and at what mileage, and the same job appearing twice in three years says more about a Insignia than any statistic about the model ever could. A mileage that goes backwards across a paperwork trail is worth walking away from whatever the badge is.
Vauxhall built its first car in Luton in 1903, spent most of the twentieth century as General Motors' British arm and now sits inside Stellantis alongside Peugeot and Citroën. Ellesmere Port built Astras until 2022 and now assembles electric vans. The Corsa is the volume car in every sense: it is back in the new car top five and it is one of the most common cars on British roads. That is context on the marque rather than on this car, and there is more of it, along with every other model line, on the Vauxhall page.
