How reliable are Seats really? We analysed 545,606 real MOT tests from the DVSA database to find out which Seat models pass most often and which years are worth buying.
This isn't survey data or owner opinions. These are actual pass/fail results from UK garages, covering Seat models sold in the UK from 2000 to 2023.
How Seat Compares to Rivals
Seat ranks #116 out of 180 manufacturers with a 73.8% average MOT pass rate. That's above the national average of 71.4%:

Top performer
The ATECA leads Seat's lineup with an 89.0% pass rate.
Proven Durability Champions: Which Seat Models Age Best?
Here's how Seat models have performed over 11+ years of real-world MOT testing, compared against 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 |
|---|---|---|---|---|---|
| MII | - | All | +8.5% | 11-14 years | 73.1% |
| EXEO | - | All | +7.1% | 15-17 years | 64.9% |
| LEON | - | All | +3.8% | 11-14 years | 68.5% |
| LEON | - | All | +1.8% | 15-17 years | 59.6% |
| ALHAMBRA | - | All | +1.5% | 11-14 years | 66.1% |
| TOLEDO | - | All | +1.4% | 11-14 years | 66.1% |
| EXEO | - | All | +1.4% | 11-14 years | 66.1% |
| LEON | - | All | +0.4% | 18-20 years | 56.5% |
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.
Early Performers: Strong Start, Unproven Durability
These newer Seat 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 |
|---|---|---|---|---|---|
| ATECA | - | All | +11.6% | 8-10 years | 87.0% |
| LEON | - | All | +4.8% | 8-10 years | 80.2% |
| ATECA | - | All | +4.3% | 3-7 years | 89.1% |
| MII | - | All | +3.5% | 8-10 years | 78.9% |
| MII | - | All | +1.6% | 3-7 years | 86.4% |
| ALHAMBRA | - | All | +1.5% | 8-10 years | 76.9% |
| ARONA | - | All | +1.3% | 3-7 years | 86.0% |
| TARRACO | - | All | +0.8% | 3-7 years | 85.6% |
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.

Seat Hybrids vs Petrol vs Diesel
Reliability varies by fuel type for Seat. Here's how each performs:
| Fuel Type | Average Pass Rate | vs National | Tests |
|---|---|---|---|
| Hybrid Electric | 88.4% | +16.9% | 1,188 |
| Electric | 85.7% | +14.3% | 301 |
| Petrol | 75.0% | +3.5% | 370,117 |
| Diesel | 71.0% | -0.4% | 173,983 |
The hybrid advantage: Seat hybrids pass MOTs 13% more often than petrols and 17% more often than diesels.
Seat Models to Avoid
Not all Seats are reliable. These specific model/year combinations have failure rates well above average:
| Model | Year | Fuel | Pass Rate | Tests |
|---|---|---|---|---|
| IBIZA | 2015 | Diesel | 61.1% | 610 |
| ALHAMBRA | 2008 | Diesel | 46.4% | 543 |
| IBIZA | 2014 | Diesel | 61.0% | 1,172 |
| ALHAMBRA | 2007 | Diesel | 47.0% | 515 |
| IBIZA | 2008 | Diesel | 47.7% | 1,152 |
| IBIZA | 2013 | Diesel | 59.0% | 3,087 |
| IBIZA | 2007 | Petrol | 48.0% | 4,023 |
| IBIZA | 2003 | Petrol | 48.1% | 1,056 |
| IBIZA | 2008 | Petrol | 48.8% | 5,194 |
| IBIZA | 2006 | Petrol | 48.7% | 2,847 |
Pattern to avoid
Early 2003-2015 petrol/diesel IBIZAs, 2007-2008 diesel ALHAMBRAs are the models that drag down Seat's average. The ALHAMBRA performs 12% worse than the average car of the same age at 21+ years - this is proven poor durability. These are the weakest performers in the lineup.
What Goes Wrong on Seats?
When Seats fail MOTs, these are the most common causes:
| Failure Category | Total Failures |
|---|---|
| 1. Lamps, reflectors and electrical equipment | 44,686 |
| 2. Suspension | 43,678 |
| 3. Tyres | 38,239 |
| 4. Brakes | 35,230 |
| 5. Visibility | 25,673 |
| 6. Body, chassis, structure | 16,011 |
| 7. Noise, emissions and leaks | 15,449 |
Pre-MOT checklist for Seat owners:
- Check all bulbs (number plate lights are commonly missed)
- Inspect suspension bushes and anti-roll bar links
- Ensure tyres meet 1.6mm tread requirement
- Check brake pad thickness and disc condition
- Clean windscreen and check wiper blade condition

About This Data
This analysis uses real MOT test results from the DVSA database, covering 545,606 tests on Seat 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).
