Dacia Sandero 2019 front left urban tracking

=14. Dacia Sandero (2013-2020)

Reliability rating: 85.9%

Owners told us that 21% of previous-generation Sanderos went wrong. The biggest areas of concern were the bodywork, engine electrics and interior trim, followed by the gearbox/clutch and infotainment/sat-nav. Two-thirds of the faulty cars took more than a day to repair, and some owners were faced with bills of up to £750.

=14. Suzuki Ignis (2016 on)

Suzuki Ignis 2019 front

Reliability rating: 85.9%

The Ignis isn’t as bullet-proof as other Suzuki models. A quarter of cars were afflicted by a problem and nearly half lingered in a garage for more than a week. Most faults occurred with the gearbox/clutch, infotainment/sat-nav and the suspension. Alongside the used Sandero (above), the Ignis is the least dependable small car.

Tesla Model S front

Reliability rating: 85.7%

The Model S is the least dependable electric car; it suffered the highest percentage of faults in our entire survey, with 61% of the cars we were told about having a problem. The most common bugbear was issues with the bodywork and non-motor electrics, followed by the brakes, motor electrics and suspension. Although all of them could still be driven, half were out of action for more than a week. And while 93% were fixed for free, the remaining owners paid out between £50 and £100 for repairs.

9. Range Rover Evoque (2011-2019)

2014 Range Rover Evoque review

Reliability rating: 82.8%

The original Evoque isn’t ageing well, with owners telling us that 35% of them went wrong in the past year. Most issues were with the bodywork and brakes, followed by engine and non-engine electrics, air-con and the engine. Around a quarter of cars were rendered undriveable and more than a third took more than a week to put right. While 95% of the remedial work was done for free, a small percentage of repair bills ranged from £300 to more than £1500. It's the poorest performing family-sized SUV. 

Seat Leon ST 1.5 TSI Evo SE

Reliability rating: 82.7%

Owners of diesel Leons had almost four times as many problems as those with petrol engines, with 40% of cars going wrong, making it the most unreliable family car. The battery was the biggest bugbear, followed by the air-con, bodywork, brakes, engine, infotainment/sat-nav and interior trim. A third of cars were rendered undriveable, and although two-thirds of the work was done under warranty, some owners paid out up to £500.

7. Porsche 718 Cayman (2016-present)

Porsche 718 Cayman T 2021 front cornering

Reliability rating: 82.5%

Owners reported that 25% of their cars had suffered a fault, and a worrying 10% of those concerned the engine. Other problem areas included the air-con, engine and non-engine electrics and interior trim. No wonder the Cayman is the lowest scorer in our coupes, convertibles and sports car category.

More than a third of cars were rendered undriveable and a quarter spent more than a week in the workshop being fixed. Only 63% of work was done for free, leaving owners to pick up bills ranging from £300 to more than £1500.

Although 36% of Velars suffered a fault, the most common issues were minor niggles with non-engine electrics and the bodywork. Other troublesome areas included the air-con, brakes, infotainment system and interior trim. Three-quarters of the afflicted cars could still be driven, but a third spent more than a week in the workshop. More than 90% of repairs were covered by the warranty, but a very small percentage of owners paid out more than £1500.
