With 1,039 MOT tests in the DVSA database, Polestar has limited test data compared to mainstream manufacturers. Here's what that data reveals about which models perform best.
This isn't survey data or owner opinions. These are actual pass/fail results from UK garages, covering Polestar models sold in the UK from 2000 to 2023.
How Polestar Compares to Rivals
Polestar ranks #31 out of 180 manufacturers with a 89.3% average MOT pass rate. That's above the national average of 71.4%:
| Manufacturer | Pass Rate | Rank | Tests Analysed |
|---|---|---|---|
| Polestar | 89.3% | #31 | 1,039 |
| Toyota | 73.8% | #115 | 1,637,457 |
| Volkswagen | 71.9% | #129 | 3,034,850 |
| Nissan | 68.6% | #142 | 1,626,183 |
| Ford | 68.5% | #143 | 4,473,074 |
| Vauxhall | 65.4% | #155 | 3,052,659 |
The verdict: Polestar leads its competitors with a 89.3% pass rate.
Best Polestar Models by MOT Pass Rate
Looking at overall reliability across all years, here's how Polestar's core models rank against the 71.4% national average:
| Model | Pass Rate | vs National (71.4%) | Tests | Years |
|---|
* Compared to overall 71.4% national average across all years. For year-adjusted comparisons that account for newer cars passing more often, see individual model breakdowns below.
Early Performers: Strong Start, Unproven Durability
These newer Polestar 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 |
|---|---|---|---|---|---|
| POLESTAR 2 PILOT PLUS EV AWD | - | All | +4.4% | 3-7 years | 89.2% |
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.
Polestar Hybrids vs Petrol vs Diesel
Here's how Polestar electric models perform:
| Fuel Type | Average Pass Rate | vs National | Tests |
|---|---|---|---|
| Electric | 89.3% | +17.9% | 1,039 |
What Goes Wrong on Polestars?
When Polestars fail MOTs, these are the most common causes:
| Failure Category | Total Failures |
|---|---|
| 1. Tyres | 69 |
| 2. Lamps, reflectors and electrical equipment | 19 |
| 3. Visibility | 11 |

Pre-MOT checklist for Polestar owners:

About This Data
This analysis uses real MOT test results from the DVSA database, covering 1,039 tests on Polestar 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).
