2017 SsangYong Musso — MOT failures & pass rate
The 2017 SsangYong Musso passed 71.7% of its 2,064 recorded MOT tests. That is 15.7 percentage points worse than all cars of a similar age, which fail at 12.6%. Failures cluster in brakes, suspension and lighting & signalling.
What the MOT record shows
No single area dominates — brakes (16.5%) and suspension (14.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, rbt (sp) and parking brake performance — coil spring alone was recorded 256 times.
Mileage is the strongest signal on the record: 19.1% of 0-30k cars fail, rising to 26.2% once past 150k.
Brakes is the most common advisory, noted on 23.3% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 23.3% | 480 |
| 2 | Tyres | 18.9% | 389 |
| 3 | Suspension | 16.0% | 331 |
| 4 | Lighting & signalling | 11.8% | 244 |
| 5 | Other defects | 6.3% | 131 |
| 6 | Steering | 5.0% | 103 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 273 | 19.1% |
| 30-60k | 843 | 28.9% |
| 60-90k | 579 | 30.7% |
| 90-120k | 225 | 29.8% |
| 120-150k | 102 | 32.4% |
| 150k+ | 42 | 26.2% |
Failure rate by age

What to check before buying a 2017 Musso
The failure pattern for this year is specific enough to inspect against: brakes accounted for 16.5% of tests. Start there.
- Brakes (16.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Suspension (14.7% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Lighting & signalling (14.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
