In our 2017 Reliability Survey, we asked more than 14,200 people to tell us about any faults their cars have suffered during the past 12 months. We asked how long the problem kept the car off the road and how much they had to pay to get it fixed. Those that cost the most and took the longest to repair gained the lowest reliability ratings.
Top three family cars aged 0-3yrs:
1. Lexus CT200h 100%
None of the Lexus CT200h owners we surveyed reported any faults with their cars, giving this premium hybrid a perfect reliability score. Even when you look at the responses from owners of cars more than three years old, less than 10% said their cars had a fault.

2. Honda Civic 94.5%
Honda’s Civic may have exterior styling that divides opinion, but owners are in agreement about its durability; only 11% of cars had issues. Areas affected included the battery, interior trim, non-engine electrics and exterior lights. All problems were fixed under warranty and most were corrected in less than a day.

Mazda 3 58.4%
Overall, 28% of Mazda 3s had faults, with petrol-engined versions afflicted by more issues than their diesel counterparts. Suspension, steering and engine electrics were the more serious areas of concern with petrol models. Not all cars were fixed under warranty and more than half spent more than a day in the garage.

Nissan Pulsar 48.3%
The Pulsar was afflicted by more than its fair share of non-engine electrical gremlins, with owners citing air-con as the most blighted area. It took more than a day to fix the majority of faults, but all the work was carried out under warranty.
