According to Warranty Direct, which studied more than 50,000 policies, one in three vehicles will develop a mechanical failure during any 12-month period. However, the figure varies dramatically depending on the make and model. For example, the frequency of failure on a Honda Civic is 8 per cent compared to 61 per cent for a Renault Grand Scenic.
Duncan McClure Fisher of Warranty Direct said: “It’s part and parcel of car ownership that, at some stage, something will go wrong. Even on the most reliable of cars, things still break sometimes.
“The worst part is the unknown – failure could happen at any time and, unfortunately, as we’re all driving evermore complex vehicles, the cost of repair is reflected.”
Warranty Direct cover starts from as little as £15 a month. For more information on the reliability of your vehicle, visit www.reliabilityindex.com, or for a quote on cover www.warrantydirect.co.uk.
