MOT test fail rates: the best and worst models

We’ve used new government data to find the best and worst MOT test fail rates in each car class and reveal the top 10 items that let motorists down.....

For many motorists, putting your car through its annual MOT test is one of the most nerve-wracking days of the year.

Once you’ve delivered the car to your local garage or dealer, you keep your phone next to you, waiting as anxiously as an expectant parent for the call to say if your car has passed and, if not, how much it’s going to cost to rectify the problems.

The MOT test is required every year for cars between three and 40 years old. But a car won’t necessarily sail through the test each year just because it’s relatively new, especially if you don’t check its basic items regularly.

According to the Driver and Vehicle Standards Agency (DVSA), nearly 50% of all faults found during MOT tests could have been avoided if the car’s owner had carried out regular checks on the most common MOT fail items, such as bulbs, tyres and wipers.

Its data reveals that more than 7.5 million of the 28.9 million cars and light commercial vehicles that underwent an MOT test in 2017 failed at the first attempt; that’s around 35% of those taking it. Lighting and signalling problems are the most common reason for failure, followed by suspension, which speaks volumes about the state of Britain’s roads. However, other easy-to-check items, such as tyres and wheels and anything that impairs the driver’s view of the road, together account for 27% of failures.

"Proper maintenance is key"

MOT technician

Neil Barlow, the DVSA’s head of vehicle engineering, said: “The MOT plays a key role in making sure the vehicles on our roads are safe to drive and meet high environmental standards. Vehicles fail their MOT for a variety of reasons, but proper maintenance is key to making sure a vehicle passes its MOT first time and remains safe to drive. By checking their vehicle all year round, motorists will also reduce the risk of causing an accident that kills or seriously injures someone.”

What Car? also regards a car’s MOT history as an important indicator of how well it has been looked after and how many components have developed faults or worn out. Both of these factors are extremely important if you’re looking for a dependable older car as a second family motor or a first car for a new driver.

To make it easier to pick the best used car, we’ve examined the data for all the cars that were tested across the country during 2017, splitting them into makes and models and calculating the percentage that failed their
test at the first attempt.

Our tables rank the best and worst cars for passing the MOT in nine classes, ranging from city cars to sports and performance cars.

Best city cars for passing the MOT test:

Skoda Citigo

The Skoda Citigo claims the top spot here by just 0.04% ahead of the Peugeot 108, demonstrating that many current city runabouts are able to sail through the annual test. Some older models do well too, in particular the previous-generation Hyundai i10, which was superseded in 2013.

Budget models from the late 1990s are now really struggling, most prominently the Daewoo Matiz. But although there are some ancient models in the basement, the poor performance of the 2004-2009 Suzuki Alto demonstrates that youth doesn’t always guarantee reliability.

Best small cars for passing the MOT test:

Mitsubishi Mirage

Japanese cars have always been known for their dependability, so it’s no surprise to see the Mitsubishi Mirage atop the pile and the Toyota Yaris and Honda Jazz in the top 10. That the Mini and the bargain Dacia Sandero defeat several other Japanese cars shows how good they are, too.

Worst small cars for passing the MOT test:

Renault Clio

The surprise entrant in the lower half of this league is the 2002-2008 Seat Ibiza, which chocked up 2% more fails than its 1995-2002 predecessor. The Peugeot 206 and Fiat Punto of similar vintage also perform poorly, although that’s not as surprising as the lowly record of the Mk2 Nissan Micra. However, the worst performer here is the old Renault Clio.

Best family cars for passing the MOT test:

Nissan Leaf

The electric Nissan Leaf has the lowest MOT fail rate of all cars tested in 2017, banishing any concerns potential buyers might have about saying goodbye to engines. The appearance of Mercedes and Volkswagen Group models in the top 10 should provide reassurance about those brands as well.

Worst family cars for passing the MOT test:

Fiat

Older French and Italian models account for nearly half of those in the bottom 10, along with two British cars: the MG ZR (a performance-focused version of the Rover 25) and the Rover 400 Series. In contrast, it’s perhaps a surprise to see a Mitsubishi near the bottom of this league.

Best small and family SUVs for passing the MOT test:

Subaru Forester

This is the category with the lowest overall MOT fail rate. While the Japanese Subaru Forester comes out on top, half of the SUVs in this category are from German brands. Vauxhall should be commended for the strength of its Mokka X, and more so Dacia for the performance of its cut-price Duster.

Worst small and family SUVs for passing the MOT test:

Jeep Patriot

With three models in the bottom 10, Suzuki has the weakest record in this category. The Jimny and Grand Vitara are ancient in relative terms, admittedly, but the SX4 isn’t. Meanwhile, the 2002-2007 Subaru Forester is four times more likely to fail its test than the stellar 2008-2012 version.

Best large and luxury SUVs for passing the MOT test:

Honda CR-V

The Honda CR-V isn’t the most expensive large SUV, but it’s certainly one of the most rugged, because it beats all of the premium brands for passing the MOT test first time. Range Rovers often perform poorly for reliability, but the current Sport bucks this trend by ranking in seventh place here.

Worst large and luxury SUVs for passing the MOT test:

Nissan Pathfinder

Jeeps look tough, but their MOT results suggest the opposite; there are two in each SUV bottom 10. The same disparity appears here for the Mitsubishi Shogun, the pick-up truck-based Nissan Pathfinder and the Nissan Terrano II. Surprisingly, the original Lexus RX does far worse than its successors.

Best MPVs for passing the MOT test:

Skoda Roomster

Don’t discount the Skoda Roomster for its odd looks; it’s a practical MPV with a great record for reliability. Less than 10% of Ford’s B-Max and C-Max models failed first time too. And if you’re after a larger people carrier, the Volkswagen Sharan and Seat Alhambra both have very strong pass rates.

Kia Carens

MPVs that arrived at the peak of the class’s popularity in the 1990s are quickly falling by the wayside; the Citroën C8, Ford Galaxy and Volkswagen Sharan all have MOT fail rates of more than 30%. But they’re not as bad as the original Kia Carens, which alarms with nearly 40% of cars failing.

Best executive cars for passing the MOT test:

BMW 4 Series

BMW’s 3 Series and 4 Series models perform well in their MOT tests, beating their rivals from Audi and Mercedes-Benz. To be expected is the strength of the much cheaper Toyota Avensis, while the surprise entry is the eccentric Citroën DS5, which manages an MOT pass rate of close to 90%.

Alfa Romeo 156

The latest Afa Romeos are proving brilliantly reliable, but the old 156 is giving credence to the brand’s historic reputation with a fail rate of 35%. Nissan and Renault models also appear prominently, while the products of the dead MG Rover company are fast disappearing from British roads.

Best luxury cars for passing the MOT test:

Aston Martin DB9

The Aston Martin DB9 appears to be almost trouble-free, with fewer than 5% failing first time. Audi is showing strongly, with the A6, A7 and A8 making the top 10, while Jaguar and Mercedes-Benz each have two cars close to the top. Notably, the former’s XJ is the only current-generation entrant.

Worst sports and performance cars for passing the MOT test:

Vauxhall Tigra

The Vauxhall Tigra has the worst MOT pass rate of any car tested in 2017; more than half failed first time. Alfa Romeo’s Brera and GT struggle too, with 25% and 38% fail rates. Mazda’s complex, rotary-engined RX-8 and Mk2 MX-5 aren’t enviable, either, with around a quarter of cars failing first time.
