2017 SsangYong Rodius — MOT failures & pass rate
The 2017 SsangYong Rodius passed 77.3% of its 3,977 recorded MOT tests. All cars of a similar age fail 12.7% of the time, so this is 10.0pp worse than the group it competes with. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
Lighting & signalling dominates the failure mix at 13.0% of all tests — 4.7 points clear of brakes, so it is the first thing to check.
At component level the recurring items are track rod end, position lamp and tread depth — track rod end alone was recorded 255 times.
Mileage matters less than usual here: the 2017 Rodius fails 14.2% of the time in the 0-30k band and 14.7% at 150k+, a spread of only 0.5 points.
Advisories point at the next bill rather than this one: tyres was flagged on 24.4% of tests without failing them.
The trend is worsening — 18.7% of tests failed in 2021 against 24.3% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 24.4% | 971 |
| 2 | Brakes | 23.6% | 938 |

What to check before buying a 2017 Rodius
On a 2017 Rodius, lighting & signalling is what the MOT record says goes wrong most — it appeared in 13.0% of tests. Check these areas before you commit.
- Lighting & signalling (13.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.3% 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.
- Tyres (6.2% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
