2021 Fiat Roller Team — MOT failures & pass rate
Across 802 MOT tests, the 2021 Fiat Roller Team recorded a 94.1% pass rate. That is 2.8 percentage points better than all cars of a similar age, which fail at 8.7%. Failures cluster in lighting & signalling, visibility and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (5.9%) and visibility (3.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and outline marker lamp — headlamp aim alone was recorded 36 times.

What to check before buying a 2021 Roller Team
On a 2021 Roller Team, lighting & signalling is what the MOT record says goes wrong most — it appeared in 5.9% of tests. Check these areas before you commit.
- Lighting & signalling (5.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.9% 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.
- Emissions & environmental (0.9% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
