Large and luxury SUVs
Most reliable: Toyota RAV4 - 99.6%
What went wrong? Engine electrics 4%
Only 4% of Toyota RAV4 owners reported experiencing an issue. The sole area concerned was engine electrics, and all cars were driveable and fixed under warranty in less than a day. It’s no wonder that more than a third of owners said their car’s reliability was one of their favourite things about it.
The BMW X5 wasn’t far behind the RAV4; only 10% of diesel examples developed a problem, with these split evenly between the engine, fuel system and wheels/tyres (all 3%). All cars remained driveable and were fixed for free in less than a week.
Although 24% of Audi Q5s had a problem, none was forced off the road, all were fixed for free and half were back in service in less than a day. Problem areas were split evenly between bodywork, fuel system, interior trim and non-engine electrics (all 6%).
Least reliable: Range Rover - 67.3%
What went wrong? Non-engine electrics 21% Suspension 17% Sat-nav 13% Battery 8% Bodywork 8% Engine electrics 8% Exterior lights 8% Wheels/tyres 8% Air-con 4% Engine 4% Exhaust 4% Gearbox/clutch 4% Interior trim 4% Steering 4%
Half of the Range Rover owners who completed the survey told us their car had a fault. Non-engine electrics were the most common issue, while a worrying 17% of cars had suspension problems. Nearly a third of cars were undriveable and two-thirds were off the road for more than a week.
The Ford Edge is on a similar level, with 54% presenting a problem. The most common troubles concerned bodywork (25%), air-con (21%) and non-engine electrics (18%). Most cars could still be driven and were repaired in less than a week, with all work done under warranty.
The Range Rover Evoque isn't as bad as its larger stablemate; 45% of cars had a problem. The exhaust (15%) was worst, then interior trim and engine and non- engine electrics (both 13%). Most remained driveable and two-thirds were fixed in less than a week, but a few owners paid up to £1500.
