Most and least reliable used cars and SUVs
We name the most dependable – and most troublesome – secondhand cars and SUVs aged from six to 20 years old, based on owners’ experiences...
Used car prices are set to soar in 2023 for several reasons, including the reluctance of many motorists to switch to electric models, the limited supply of fairly new models due to the pandemic, and demand for cleaner used cars for use in low-emission zones.
That means it’s more important than ever to choose your second-hand car wisely, and reliability is a crucial factor in keeping costs down – especially if you’re buying an older car that’s no longer covered by the manufacturer’s warranty.
A dependable model shouldn’t land you with anything other than routine servicing and maintenance bills for the foreseeable future. However, if you pick a car that’s prone to faults, you could end up facing a constant barrage of expensive repair bills.
How we compiled our ratings
We asked owners to tell us if their car had broken down in the previous 24 months. To highlight the most common fault areas for each model, we asked all those who said yes, to tell us which of 15 different areas of the car were concerned: air-con, battery, bodywork, brakes, clutch/gearbox, engine, engine electrics, exhaust, fuel system, infotainment/sat-nav, interior trim, non-engine electrics, steering, suspension and other.
And, to measure the seriousness of each fault, we also ask how long each car took to be repaired and how much the work cost. The worst offenders – cars that were off the road for more than a week and cost more than £1500 to fix – receive the lowest reliability ratings. Those with minor niggles that were fixed for free gained higher scores. Our data encompasses 400 models from 30 brands.

The most reliable small cars
1. 2015-2020 Honda Jazz
Reliability rating 100%
What went wrong? Nothing
The third-generation Jazz offers the low running costs you’d expect of a small car and the space and practicality of a mini MPV. On top of that, it’s very unlikely to let you down because it’s extremely robust. In fact, not a single older Jazz suffered any faults at all, according to the owners who completed our survey.
2. 2011-2020 Toyota Yaris
Reliability rating 98.6%
Toyota has a rock-solid reputation for building dependable cars – it’s been in the top three brands in our newer car reliability survey for the past six years, so it’s a great choice if you want a car that won’t let you down. Just 5% of the cars we were told about had a problem and the only area concerned was the suspension. All faulty cars were repaired and back on the road in a day or less, and bills were minimal: half of owners paid out no more than £50 and the rest paid less than £300.
3. 2010-2017 Suzuki Swift
Reliability rating 98.1%
The Swift might not be the most popular small car, but it’s got a lot going for it, including great driving manners, a reasonable amount of space and a high rating for safety. Like other Suzuki models, it’s also bulletproof, even as it ages. Only 6% of the Swifts in our survey developed a fault, and the battery was the only component affected. All cars could still be driven and half were fixed in less than a day, and no repair bills exceeded £100.
The least reliable small cars
3. 2010-2016 Nissan Micra
Reliability rating 66.4%
The Micra suffers more than its fair share of problems, according to owners, who told us 47% of their cars had gone wrong in the previous 24 months. The most common gripe was about the suspension, affecting 29% of faulty cars, followed by the engine’s electrical systems (18% of faults). Problems rendered 50% of cars undriveable, and kept a similar proportion in the garage for up to a week. Cars were often costly to put right. Although a third of repairs came in at less than £200, the other two thirds ranged from £201 to £1000.
2. 2002-2008 Ford Fiesta
Reliability rating 65.5%
The Fiesta is cheap to buy and fun to drive, but it’s no joy to live with if you get one that suffers a string of costly faults. And that is a possibility, because owners told us that 46% of their cars had suffered an issue. The most frequent trouble-spot was the suspension, affecting 18% of broken cars, but there were also issues with the air-con, bodywork, exhaust and gearbox. Two thirds of faulty cars could still be driven, and 45% were out of the workshop in less than a week, but some repair bills were pricey. Although 64% of bills were below £200, the rest ranged from £201 to £750 per repair.
1. 2010-2016 Citroën C3
Reliability rating 53.0%
What went wrong? Air-con, brakes 13%, engine, exhaust, gearbox/clutch, suspension 9%, battery, engine and non-engine electrics, fuel system, sat-nav, steering 4%
A wide range of issues affected the C3s we were told about, but the most frequent were with the air-con and braking system. They rendered more than 50% of cars undriveable, and kept 40% of them in the garage for more than a week. The only good news is that 10% of faulty cars were fixed for free and 43% of bills totalled less than £200, but the remaining owners had to find between £201 and £750 to get their cars put right.
