Most and least reliable executive cars

While the best executive cars are refined, efficient and packed with the latest tech, reliability is also important. So, which are the most and least dependable?...

Most and least reliable executive cars

Executive cars are relied on by company car drivers who use them for business during the week and as family cars at the weekend. So, as well providing a plush and practical interior, good mile-munching ability and the latest infotainment tech, they need to be robust – and that's where our Reliability Survey comes in.

We asked more than 18,000 people to tell us about any faults their cars had suffered during the past 12 months. We asked how long each problem kept the car off the road and how much (if anything) the repairs had cost.

Those cars that suffered the fewest problems and were cheapest to fix gained the highest scores, while those that languished in workshops for days on end and racked up expensive repair bills were penalised the most heavily.

Here we count down the most and least dependable executive cars aged up to five years old. Or to tell us about your own car, complete our 2020 Reliability Survey.
