Japanese cars are the most reliable engines on the market, and high-end Tesla & # 39; s will probably lower their owners.

According to a well-reviewed reliability study, it appears that Suzuki, together with four other Japanese brands, is among the top six of the most robust, while the American company for electric cars has the most unstable track record.

The What Car? Reliability research also mentions the most and least reliable new models you can buy today in showrooms, based on feedback from more than 18,000 drivers.

Meanwhile, exclusive data released to This is Money and MailOnline also tells you which used car & # 39; s you can rely on … and which do not.

The survey is one of the largest of its kind in the UK and handles the feedback from 18,284 owners of about 159 models from 31 different brands.

Suzuki, who mainly makes cheap and cheerful little cars & 4×4 & # 39; s, topped the manufacturer's list for new cars up to four years old with a reliability score of 97.7 percent, followed by Lexus, Toyota, Mitsubishi and Subaru in the top six.

The only non-Japanese brand in the highest order was the Korean firm Kia, which took fourth place, with its sister brand Hyundai as ninth.

On the other side of the spectrum, it was the American luxury car electric giant Tesla who recorded the worst reliability track record.

Despite the fact that the cheapest brand new Tesla buyers returned more than £ 60,000, the reliability score of 57.3 percent was by far the worst score.

Land Rover – which was second from below – scored 76.5 percent for the reliability of cars between one and four years old.

The trend continued when the data showed which specific models were the most and least reliable.

For newer cars it was the current Toyota Yaris and Suxuki SX4 S-Cross that were in charge, both with an astounding 100 percent confidence record, according to their owners.

The electric Nissan Leaf was third, for the Toyota RAV4 and BMW 3-series.

Anchoring the rankings was the Tesla Model S, which costs £ 61,600 in the United Kingdom.

Reports from owners of defects and necessary repairs achieved a reliability score of only 50.9 percent, almost half of the most reliable Japanese cars.

And it does not make a good reading for Land Rover, with three of its models – the Discovery Sport, Range Rover and Range Rover Evoque – among the top five models with the worst owner ratings.

In general, about 30 percent of respondents with cars less than four years old said that their car had suffered at least one error in the past 12 months.

Steve Huntingford, chief editor of What Car ?, said: "Reliability is a big consideration for every potential buyer of a car, because your car is probably your second largest monthly expense after mortgage or rental payments.

& # 39; You want your car to last a long time and you do not want to handle huge amounts to solve and maintain failures.

& # 39; Our annual survey has shown that it is Japanese models that continue to dominate the top of the reliability rankings, both for the car model and for the brand. & # 39;

Used cars on which you can and can not count

This is Money has worked with What Car? to also reveal which older used cars & # 39; s you should and should not consider buying on the second hand market.

This is based on the feedback from owners of cars between 4 and 12 years old, so those built between 2014 and 2006.

These are the most reliable five models and the models with the worst reliability score of their owners.

Most reliable used car & # 39; s

1. Toyota RAV4 (2013-2018) – 100% reliability score

The Toyota RAV4 is designed as a robust offroader. Glowing feedback from the owner saw it score a remarkable 100% reliability rating

Only six percent of Citigos had a problem. Brakes and braking systems were the only bicycles, although cars were still steerable and were repaired in the same way the same day.

3. Toyota Yaris Hybrid (2011-present) – 99.1% reliability score

The Yaris Hybrid was for some time one of the smallest cars that were for sale with a combination of petrol and electricity. It is as reliable as green

More than two in five cars had at least one fault. A quarter of the owners reported suspension problems, while 21 percent had problems with the gearbox and the clutch. About half of them remained mobile and most were repaired under warranty, but a small percentage of the owners had to pay more than £ 1,500 if they were billed by garages.

2. Range Rover (2002-2013) – 35.4% reliability score

Land Rover simply can not shock that bad reliability record. For a car that has to deal with mountains, it seems only to scale service lifts in garages

About 56 percent of the cars had a problem. The most common problems were the battery (28 percent) followed by engine repairs, engine electricity, exhaust fumes, fuel system, suspension and wheels and tires, all at 11 percent of cars. Most cars could still be driven, but more than half of the owners paid between £ 500 and £ 1,000.

3. Jaguar XJ (2010-present) – 38.1% confidence score

The Jaguar XJ is the British brand's answer to the popular German luxury saloon carriages. Unfortunately, they are more problematic than premium

Like the Range Rover, 56 percent of cars had an error. A quarter of these were motor-electric, while 13% of the models had to have the brakes, engine or exterior lights repaired. Two-thirds of the car's could still be driven, but many owners paid £ 300 to £ 500.

4. Volkswagen Polo (2002-2009) 38.4% reliability score

Two out of five cars had an error, 27 percent of which related to the brakes and 20 percent linked to the components of the suspension. More than half could not be driven and took more than a day to repair, but most repair bills were less than £ 200.

5. BMW 1 series (2004-2011) – 40.1% reliability score

The first generation 1 series was a huge step in the hatchback market for BMW. It seems that this original attempt is not so reliable
