Volvo XC90 MOT pass rate: what 99,884 tests reveal about two very different cars

The Volvo XC90 has an overall MOT pass rate of 78.0% across 99,884 DVSA tests. That is a decent number. It sits comfortably above most large SUVs. But it hides the most dramatic generational split in our entire dataset.

The first generation XC90 (2003 to 2014) was built on Volvo's P2 platform, shared with the S60 and V70. It used a range of five-cylinder and six-cylinder engines, with an Aisin Warner TF80 six-speed automatic gearbox that became notorious for valve body failures and harsh shifting. These cars pass their MOT between 66% and 78% of the time depending on age. For a premium SUV, that is mediocre.

The second generation (2015 onwards) is a completely different car. Built on Volvo's new Scalable Product Architecture (SPA) platform after the Geely acquisition, it uses a family of two-litre four-cylinder Drive-E engines (including plug-in hybrid T8 variants). Auto Express described the 2015 launch as leaving "no stone unturned" with an "all-new platform and modular four-cylinder engines." The MOT data shows the difference immediately: pass rates jump to 84% and climb to 89%. That is a transformation.

The 2003 XC90 passes at just 66.0%. These are 20-year-old cars with an average mileage of 152,687 miles, still being presented for testing. At the other end, 2020 models pass at 89.0% with an average of 41,347 miles. That is 23 percentage points of improvement and over 100,000 fewer miles on the clock.

Year by year

The year-by-year data tells a clear story. Gen 1 improves slowly as newer cars enter the test pool, then Gen 2 arrives and the pass rate steps up by six points overnight.

Notice the mileage column. The 2004 models average 161,385 miles. These are cars that have covered enormous distances and are still being MOT tested, which speaks to the XC90's fundamental durability even when it does not pass. A 66% pass rate at 160,000 miles is not the same as 66% at 60,000 miles.

The Gen 1 improvement from 2003 (66.0%) to 2014 (78.3%) is partly about lower mileage on newer cars, but the 2012 to 2014 models also benefited from Volvo's late-life revisions: improved suspension components and the updated D5 diesel engine.

Then 2015 arrives and the pass rate jumps from 78.3% to 84.0%. That is 5.7 percentage points in a single model year. The SPA platform brought completely new suspension geometry, new electrical architecture, and the Drive-E engine family that replaced the ageing five-cylinder and six-cylinder units.

What fails: Gen 1

The first generation XC90 has a clear weak point: suspension. Worn bushes and joints are the single most common failure reason for 2003 to 2008 models, appearing in roughly one in nine failed tests. The multi-link front suspension and the rear suspension trailing arm bushes wear out, particularly on cars that have covered high mileage on poor roads.

Headlamp aim is the second biggest issue. The Gen 1's self-levelling headlamps rely on sensors linked to the suspension, and when the suspension wears, the headlamp aim drifts with it. Fixing the suspension often fixes the headlamp issue too.

Parking brake failures appear from 2006 onwards. The electronic parking brake on later Gen 1 models is a known problem area. Seized calipers and worn cables are common, and the repair is not cheap.

What fails: Gen 2

The Gen 2's failure profile is completely different. Suspension bush wear drops dramatically. Instead, the top failures are tyres and brake pads. That is a sign of a fundamentally well-built car: the things that go wrong are consumables, not structural components. Autocar notes that "non-hybrid models are prone to excessive brake wear" and flags air suspension compressor failures as a known issue on cars so equipped. Our data confirms the brake pad finding.

Tyre damage is the most common Gen 2 failure. The XC90 is a heavy car (over 2,000kg) running on large alloy wheels, typically 19 or 20 inches. Kerbing, potholes, and sidewall damage are more consequential than on a lighter car with smaller wheels. Budget for premium tyres and inspect them regularly.

Brake pad wear ranks second. The XC90's weight means brake pads wear faster than on smaller SUVs. This is not a design flaw; it is physics. A pre-MOT check through a service like BookMyGarage can flag pads and tyres before they become a formal failure.

The Gen 1 buying case

The first generation XC90 is now very cheap. You can find running examples for under £3,000. At that price, a 70% MOT pass rate is not necessarily a dealbreaker, but you need to know what you are getting into.

The Aisin Warner TF80 automatic gearbox (fitted to most UK cars) is the big-ticket worry. Specialist Volvo garages report that valve body failures cause harsh shifting and slipping, and a rebuild can cost £2,000 to £4,000. The D5 diesel is generally more robust than the T6 petrol, and post-2007 D5s with the upgraded engine are the pick of the Gen 1 range. Budget for suspension work (bushes, drop links, anti-roll bar links) and check the electronic parking brake carefully.

If you are buying Gen 1, target 2012 to 2014 models. At 75.9% to 78.3%, these late cars benefit from the accumulated improvements and still have lower mileage than the earliest examples. The average 2014 car has done 99,570 miles, which is manageable for a Volvo.

The Gen 2 buying case

The second generation XC90 is one of the strongest large SUVs in our data. At 88% to 89% for 2017 to 2020 models, it matches or beats the BMW X5 and sits well above the Audi Q7 and Land Rover Discovery. The T8 plug-in hybrid variants (which make up a significant proportion of UK sales) show pass rates above 88% across the board.

Prices for a 2017 Gen 2 start around £18,000 to £22,000. That gets you a car that passes its MOT nearly nine times out of ten, with Volvo's comprehensive safety systems and a refined cabin. The D5 diesel was the volume seller but has been discontinued; the B5 mild hybrid (2020 onwards) is the current pick.
