The most reliable car brands - and the least

Some cars never seem to be out of the garage for long, while others rarely end up there between services. Here we look at the best and worst brands for reliability...

Some people switch brands every time they replace their car, but many stick with the same make through thick and thin – and a big reason for this is reliability.Image 1 of 15

To save you from finding out the hard way which brands are the most – and least – dependable, we asked the owners of nearly 13,000 cars to tell us if their vehicles had suffered from any faults in the previous 12 months.

We classified the faults into 15 groups: air-con, battery, bodywork, brakes, engine, engine electrics, exhaust, fuel system, gearbox/clutch, interior trim, non-engine electrics, steering, suspension, wheels/tyres and other.

For each fault, we asked the owner to tell us how much the car cost to repair and how much time it had spent getting fixed. We used this information to work out a unique reliability rating for each model, with those that cost the most and were off the road longest penalised more severely than those that had few or no faults and cost little or nothing to fix.
