The first off-roaders were designed to tackle any terrain and be easy to fix in the worst conditions the world has to offer. These days, however, SUVs are mainly used on the road and will never be repaired by their owners.
That's not to say they will never break down, though, so it's useful to know which are the most reliable 4x4s and SUVs on sale now - and the Driver Power 2014 survey has revealed the top models.
With over 50,000 responses from car owners across the UK, the Driver Power is the biggest survey of its kind and gives us a unique insight into the reliability of the cars on sale in Britain. Here we've listed the top 10 most reliable cars, as rated by their owners, in the 4x4 category.
Thanks to the survey data there are results for over 30 4x4s and SUVs, and you can see the full list of cars at the bottom of this page. Japanese, German and French manufacturers have done well in the reliability rankings this year, with Land Rover falling to the bottom of the table - in fact, three of its models sit at the bottom of our table. Don't be to put off by that, however, as the ratings for reliability were still over 80 per cent.
Driver Power reliability score: 94.12%
The new Nissan Qashqai follows on from the strengths of the original model by offering low running costs and everyday practicality mixed with the styling of an SUV. There's loads of in-car tech too, including front collision avoidance, drowsiness detection, blind spot warning, traffic sign recognition and cameras to help you park.
That means it's a very safe car, but it also impressed owners when it comes to reliability. The car hasn't been out too long, so it's hard to say if it will be reliable in the long term, but we do know that the Qashqai has impressed its owners so far.
Driver Power reliability score: 94.15%
With some of Land Rover's models languishing at the bottom of the table (see below), it's a surprise to see the Evoque scoring so highly for reliability - but it proves that this new model has been engineered well and is impressing its owners in this category.
There have been a few recalls over the time the car has been on sale, but it does look like owners are satisfied with the car overall - it ranked a respectable 36th overall in the top 150 cars.
Driver Power reliability score: 94.19%
The BMW X3 is one of the top cars to own in the UK, according to owners, who rated it highly for performance, ease of driving, ride quality and (importantly) reliability. That means it placed 12th overall in the top 150 cars, but an handy 8th out of all the 4x4s and SUVs for reliability.
The X3 is a solid choice however you look at it with its spacious interior, comfortable ride and range of efficient and powerful diesel engines.
Driver Power reliability score: 94.74%
The Mazda CX-5 is a stylish and well-equipped SUV with a range of efficient engines - and it's also one of the most reliable SUVs out there, with owners rating it highly for both reliability and build quality. It also benefits from a five-star Euro NCAP score and a host of extra safety equipment included on the options list, so it makes a great family car.
Driver Power reliability score: 94.83%
Although owners didn't rate the Dacia Duster, Britain's cheapest SUV, highly for build quality, it appears they haven't had too much trouble with it breaking down, as it nearly reached the top five for reliability in the SUV class.
It's an excellent choice if you're looking for a cheap, dependable runabout capable of taking on some rougher rural roads. Thanks to the low price you might consider buying new when you would otherwise go for a used car, so there's the benefit of a manufacturer warranty as well.
Driver Power reliability score: 94.83%
The Honda CR-V pipped the Dacia Duster into the top five by such a small amount that you have to look at the third decimal place to separate them. Honda has a strong reputation for reliability and the CR-V making this list will be no surprise to many. It scored equally highly for build quality in the survey - in fact, it scored highly in nearly every category, so the Honda is one of the best cars in this class to own.
Driver Power reliability score: 95.04%
The Renault Captur is a new crossover based on the Clio, and it boasts stylish looks, a practical interior and a strong result in the reliability category.
Its owners can't have owned one for very long, as it makes its Driver Power debut this year, so we can't be sure about long-term reliability, but the range of engines is tried and tested in the Clio, so it should prove to be dependable.
Driver Power reliability score: 96.45%
The Skoda Yeti has taken the top spot in the Driver Power's top 150 cars list for three years running, and with top scores in almost every category, including reliability, it's easy to see why.
The Yeti came in 8th place out of all the cars on sale for reliably, making it the third-best SUV, but it topped the overall chart for ease of driving. It's a very practical family car with an affordable price and excellent build quality - a great overall choice.
Driver Power reliability score: 96.47%
The Peugeot 2008, like the Renault Captur, is a fairly new model - so we can't judge its long-term reliability. However in its first year on sale its owners have rated it very highly in this category. With low running costs, SUV looks and the practicality of a hatchback at a price just above that of the 208 supermini, it's easy to see why the 2008 is a desirable car - and this excellent reliability score can only help that.
Driver Power reliability score: 96.83%
The Audi Q3 is another newcomer to the Driver Power survey, but with a very strong reliability score it looks like the Audi Q3 is shaping up to be a dependable choice of small SUV. It certainly beats it main rival, the BMW X1, which didn't even make the top 10 for reliability - and that will be an important factor for those looking to buy one of these premium crossovers. The Audi Q3 ranked 17th overall in the survey, let down by its low practicality score.
