Proven Durability Champions: Which Fiat Models Age Best?
These Fiat models have proven exceptional durability with 11+ years of real-world MOT data. They consistently outperform the national average for cars of the same age:
High-confidence data: Only vehicles with 11+ years of MOT history and 100+ tests are included in this ranking.
| Model | Year | Fuel | vs Same-Age Average | Tested At | Pass Rate |
|---|---|---|---|---|---|
| AUTO TRAIL | - | All | +21.7% | 11-14 years | 86.3% |
| DUCATO | - | All | +17.6% | 15-17 years | 75.5% |
| UNCLASSIFIED | - | All | +17.3% | 11-14 years | 81.9% |
| DUCATO | - | All | +16.4% | 11-14 years | 81.1% |
| MOTORHOME | - | All | +15.1% | 18-20 years | 71.2% |
| DUCATO | - | All | +10.9% | 18-20 years | 67.1% |
| COUPE | - | All | +4.4% | 21+ years | 65.3% |

| MOTOR | - | All | +1.8% | 21+ years | 62.8% |
| DOBLO | - | All | +1.8% | 11-14 years | 66.4% |
How to read this: A score of "+15%" means the model passes MOTs 15 percentage points more often than the average car of the same age. These are proven results from vehicles that have genuinely aged well.
Proven durability champion
The AUTO TRAIL outperforms the average 11-14 years-old car by 22 percentage points, with 1,221 MOT tests proving its reliability.
Early Performers: Strong Start, Unproven Durability
These newer Fiat models (3-6 years old) show strong early results, but haven't yet proven long-term durability:
Important caveat: Durability NOT yet proven - too early to assess long-term reliability. Older versions of the same model may tell a different story at 11+ years.
| Model | Year | Fuel | vs Same-Age Average | Tested At | Pass Rate |
|---|---|---|---|---|---|
| AUTO TRAIL | - | All | +14.8% | 8-10 years | 90.3% |
| UNCLASSIFIED | - | All | +13.0% | 8-10 years | 88.4% |
| 124 | - | All | +10.0% | 8-10 years | 85.5% |
| DUCATO | - | All | +7.9% | 8-10 years | 83.3% |
| ROLLER TEAM | - | All | +7.0% | 8-10 years | 82.4% |
| AUTO TRAIL | - | All | +6.3% | 3-7 years | 91.0% |
| UNCLASSIFIED | - | All | +6.2% | 3-7 years | 91.0% |
| ROLLER TEAM | - | All | +3.1% | 3-7 years | 87.9% |
What this means: These models are performing well in their early years, but we recommend checking the Durability Champions section above to see how older versions of the same model family have fared over time.

Fiat Hybrids vs Petrol vs Diesel
Reliability varies by fuel type for Fiat. Here's how each performs:
| Fuel Type | Average Pass Rate | vs National | Tests |
|---|---|---|---|
| Hybrid Electric | 84.9% | +13.5% | 53 |
| Electric | 77.3% | +5.8% | 22 |
| Diesel | 70.1% | -1.3% | 228,551 |

The hybrid advantage: Fiat hybrids pass MOTs 18% more often than petrols and 15% more often than diesels.
Fiat Models to Avoid
Not all Fiats are reliable. These specific model/year combinations have failure rates well above average:
| Model | Year | Fuel | Pass Rate | Tests |
|---|---|---|---|---|
| TALENTO | 2017 | Diesel | 66.2% | 618 |
| DOBLO | 2020 | Diesel | 72.2% | 615 |
| DOBLO | 2017 | Diesel | 66.7% | 2,237 |
| FIORINO | 2014 | Diesel | 57.4% | 1,033 |
| FIORINO | 2015 | Diesel | 61.2% | 817 |
| DOBLO | 2019 | Diesel | 72.0% | 1,357 |
| DOBLO | 2015 | Diesel | 61.7% | 4,350 |
| FIORINO | 2016 | Diesel | 65.0% | 505 |
| DOBLO | 2018 | Diesel | 70.6% | 1,688 |
| DOBLO | 2016 | Diesel | 65.7% | 3,297 |
Pattern to avoid
Early 2015-2020 diesel DOBLOs, 2014-2016 diesel FIORINOs are the models that drag down Fiat's average. The SCUDO performs 12% worse than the average car of the same age at 11-14 years - this is proven poor durability. These are the weakest performers in the lineup.
What Goes Wrong on Fiats?
When Fiats fail MOTs, these are the most common causes:
| Failure Category | Total Failures |
|---|---|
| 1. Suspension | 98,550 |
| 2. Lamps, reflectors and electrical equipment | 96,227 |
| 3. Brakes | 56,754 |
| 4. Tyres | 48,005 |
| 5. Visibility | 44,052 |
| 6. Body, chassis, structure | 34,939 |
| 7. Noise, emissions and leaks | 29,884 |
Pre-MOT checklist for Fiat owners:
- Inspect suspension bushes and anti-roll bar links
- Check all bulbs (number plate lights are commonly missed)
- Check brake pad thickness and disc condition
- Ensure tyres meet 1.6mm tread requirement
- Clean windscreen and check wiper blade condition

About This Data
This analysis uses real MOT test results from the DVSA database, covering 793,773 tests on Fiat vehicles between 2000 and 2023.
Year-Adjusted Scoring (v2.1): In year-by-year breakdowns, each vehicle is compared against the national average for vehicles of the same model year. This removes the natural bias where newer cars pass more often, allowing fair comparisons across eras.
Evidence-Tiered Durability: We separate "proven durability" (vehicles tested at 11+ years old) from "early performers" (3-6 years old). Only vehicles with proven long-term data are used for durability claims. Age-band comparisons use weighted national averages.
Minimum thresholds: 100 tests for proven durability rankings, 100 tests for early performer rankings. Pass rates are calculated as first-time passes, excluding retests.
The overall national average MOT pass rate is 71.44% based on 32,300,000 tests across all manufacturers. Year-specific averages range from ~59% (2009 vehicles) to ~88% (2020 vehicles).
