SsangYong Musso MOT Failures
An analysis of 42,101 real DVSA MOT tests on the SsangYong Musso — what fails, how often, and how that compares to every other car on UK roads. Generations covered: G2 (2016–2022).
Where the SsangYong Musso fails its MOT
The single biggest MOT failure point on the SsangYong Musso is parking brake inoperative on one side — this model is 81 times more likely to fail on this item than the average car on UK roads. That makes it a major concern for anyone buying or owning this model. Across 42,101 MOT tests, 3.37% of all SsangYong Musso tests recorded this as a failure.
Brake failures on the MOT range from worn pads and discs (routine maintenance) to corroded brake lines and seized calipers (more serious). Check for any pulling under braking and listen for grinding.
Other notable weak points include parking brake efficiency less than 50% of the r... (51x the fleet average), obligatory rear fog lamp missing, or a front or... (23x the fleet average), reflector defective or damaged by up to 50% of ... (27x the fleet average), and transmission joint, belt or chain worn (219x the fleet average). These ratios compare the SsangYong Musso's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Brakes, Lights & Electrics, Bodywork, Steering, Suspension. If you're inspecting a SsangYong Musso before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The SsangYong Musso's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the SsangYong Musso specifically, the DVSA data shows the most common failures at this mileage are transmission joint, belt or chain worn (184x the average) and parking brake efficiency less than 50% of the r... (51x). parking brake inoperative on one side (31x) and reflector defective or damaged by up to 50% of ... (27x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the SsangYong Musso specifically, the DVSA data shows the most common failures at this mileage are transmission joint, belt or chain worn (82x the average) and parking brake inoperative on one side (24x). parking brake efficiency less than 50% of the r... (18x) and reflector defective or damaged by up to 50% of ... (13x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the SsangYong Musso specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (402x the average) and parking brake inoperative on one side (13x). parking brake efficiency less than 50% of the r... (11x) and parking brake efficiency less than 50% of the r... also appear frequently.
The shift from transmission joint, belt or chain worn at lower mileages to lamp missing, inoperative or in the case of a m... at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that SsangYong Musso specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Parking brake system failure (G2) Dangerous
MOT statistics show systematic parking brake failures across multiple defect categories, with this model failing at up to 81.4 times the national average. Affects G2; typical independent garage repair cost is £200–£500.
Steering ball joint premature wear (G2) Dangerous
MOT data shows steering ball joints developing excessive wear or free play at 16.2 times the national fleet average, with failures recorded from 20,000 miles onwards. Affects G2; typical independent garage repair cost is £150–£350.
Transmission drive belt or chain excessive wear (G2) Major
MOT data shows this model fails transmission drive component inspections at 218.5 times the national fleet average, with failures concentrated between 40,000-60,000 miles on the 2.2 diesel engine. Affects G2; typical independent garage repair cost is £300–£800.
Suspension spring fracture (G2) Major
MOT evidence shows suspension springs fracturing or becoming seriously weakened at 13.7 times the fleet average, with failures occurring from very low mileages including the 0-20,000 mile band. Affects G2; typical independent garage repair cost is £200–£400.

What to check before buying a SsangYong Musso
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a SsangYong Musso:
Brakes — check for parking brake inoperative on one side, parking brake efficiency less than 50% of the r.... Lights & Electrics — check for obligatory rear fog lamp missing, or a front or..., reflector defective or damaged by up to 50% of ..., lamp missing, inoperative or in the case of a m....
Beyond the MOT items, ask specifically about parking brake system failure and steering ball joint premature wear. These won't show up on a standard MOT but can be expensive to fix — repairs start from £200. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
