Score 85.1%

Just over a third of F-Pace owners reported a fault with their car; the most frequently cited issues were with the bodywork. Non-engine electrical systems and sat-navs were also problematic, and there were fuel system and suspension issues too. The vast majority of cars could still be driven, though, and all were fixed under warranty.

The latest big Volvo 4x4 isn’t as rugged as it looks – 56% of the cars we were told about had suffered a fault. Most problems were with non-engine electrics, followed by bodywork issues and malfunctioning sat-navs. Almost all cars could still be driven and all the glitches were fixed under warranty.

Score 84.4%

The X-Trail may look tough, but its electrical systems suffer more than their fair share of problems. Owners told us 43% of X-Trails had a fault; while most were minor electrical issues, some were with the engine. Around a third of cars were rendered undrivable, but most were repaired for free.

Jaguar XE

17. Jaguar XE (2015-present)

Score 83.7%

Jaguar XE owners spend a lot of time in dealerships, because 42% of their cars had a fault. While there were problems in every area, the most frequent were brakes and interior trim (both 11%) and electrics (10%). Most cars remained drivable and were fixed in less than a day, but a few owners had to pay £500-£750.
