10. Jaguar XF (2015-present)

Score 81.9%

Newer Jaguar XFs proved the less durable than older ones, with 36% going wrong. While some had issues with their engine, fuel system and gearbox, by far the most common issues were with the electrics. Bodywork issues were also highlighted. All cars were fixed under warranty, but a large proportion were stuck in the garage for more than a week.

9. Peugeot 308 (2014-present)  

Score 81.5%

The Peugeot 308 is even less reliable than the smaller 208, with nearly half of examples suffering a fault. Again, the majority were electrical issues. The areas concerned included heated seats, the infotainment system and parking sensors. Most cars could still be driven, but a few owners were charged up to £500 for the work.

Range Rover Sport

6. Range Rover Sport (2014-present)

Score 75.8%

According to owners, 38% of Range Rover Sports have had a problem in the previous 12 months. The most commonly cited area was engine electrics, followed by the suspension, exhaust system, sat-nav, other non-engine electrics and interior trim. The faults rendered half of cars undrivable, but all were fixed for free.
