2022 SsangYong Musso — MOT failures & pass rate
1,172 MOT tests on the 2022 SsangYong Musso are in this dataset, and 77.3% of them passed. All cars of a similar age fail 8.1% of the time, so this is 14.6pp worse than the group it competes with. Failures cluster in brakes, lighting & signalling and visibility.
What the MOT record shows
One area stands out: brakes, recorded in 15.8% of tests against 11.0% for the next-worst category.
At component level the recurring items are rbt (sp), parking brake performance and rear fog lamp — rbt (sp) alone was recorded 123 times.
Mileage is the strongest signal on the record: 16.3% of 0-30k cars fail, rising to 22.6% once past 90-120k.
Brakes is the most common advisory, noted on 20.5% of tests — work that passed today but is likely due soon.

| 0-30k | 386 | 16.3% |
| 30-60k | 552 | 25.9% |
| 60-90k | 195 | 25.6% |
| 90-120k | 31 | 22.6% |
Failure rate by age

What to check before buying a 2022 Musso
The failure pattern for this year is specific enough to inspect against: brakes accounted for 15.8% of tests. Start there.
- Brakes (15.8% 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.
- Lighting & signalling (11.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (4.2% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
