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.
Top of the charts: Suzuki has been named the most reliable car brand by a new poll of more than 18,000 drivers. The Sx4 S-Cross (photo) was the most reliable new car in the What Car? Reliability study 2018
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.
Eles Musk & # 39; s Tesla came down the brand ranking with a low reliability score of only 57.3%. The £ 60,000 Model S (photo) was also called the least reliable model

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.
The Toyota Yaris (left) was the model with the highest reliability score of 100%. The recently replaced Nissan Leaf (right) is number 3 and is the most reliable electric car

Looking away Land Rover: the British brand had three separate models in the list of the 5 most unreliable new cars. That included the £ 81,500 Range Rover (photo) with a score of only 67.3%
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
One of the trim levels of this RAV4 generation is & Invincible & # 39 ;. It makes the name true. No errors were reported in cars from before 2015.
2. Skoda Citigo (2012-present) – 99.3% reliability score
The Citigo is Skoda's answer to cheap and cheerful driving. It is also reliable, according to owners
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
Only eight percent of the car's had a problem, with those who were underage as a battery and automatic wipers. All cars that are fixed in less than a day and repair costs were not more than £ 100.
4. BMW X5 (2013-present) – 98.9% reliability score
While previous versions of the X5 are remembered as being flaky when it comes to reliability, the current model is the opposite
Only seven percent of the X5s had a problem, with outlets being the only stated error. All cars were repaired the same day under warranty.
5. Lexus CT (2011-present) – reliability score of 98.8%
Lexus has always had a very strong track record in reliability, often at the top of these surveys. The CT hatchback is no different
Only five percent of Lexus' hybrid hatchback had to be repaired, with radio, satellite navigation and tire pressure warning systems being minor headaches. All cars could still be driven and were repaired the same day under warranty.
Leastly reliable used cars
1. Alfa Mito (2008-present) – 27.7% reliability score
It is no surprise to see an Alfa in the list. De Mito scored a pitiful 27.7% reliability rating, based on feedback from the owner
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
Many younger drivers may be tempted by a second-hand Polo like this, but What Car? the readers say that they often suffer from problems
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
Almost three out of five cars (58 percent) had problems. About 16 percent was related to batteries and engines, while 13 percent had problems with the brake. Two-thirds of the car's could still be driven, but some repair laws amounted to £ 1500.
