Ds has built its reputation on reliability, but does the data back it up? We analysed 42,429 real MOT tests from the DVSA database to find out exactly which Ds models live up to the hype and which ones fall short.
This isn't survey data or owner opinions. These are actual pass/fail results from UK garages, covering every Ds model sold in the UK from 2000 to 2023.
How Ds Compares to Rivals
Ds ranks #46 out of 75 manufacturers with a 71.4% average MOT pass rate. That's below the national average of 71.5%:
| Manufacturer | Pass Rate | Rank | Tests Analysed |
|---|---|---|---|
| Toyota | 74.0% | #31 | 1,606,300 |
| Volkswagen | 72.2% | #43 | 2,967,545 |
| Ds | 71.4% | #46 | 42,429 |

| Ford | 68.5% | #51 | 4,432,652 |
| Vauxhall | 65.4% | #59 | 3,038,498 |
The verdict: Toyota maintains a lead among competitors, while Ds sits at #46. However, newer Ds models significantly outperform this average.
Best Ds Models by MOT Pass Rate
Looking at overall reliability across all years, here's how Ds's core models rank against the 71.5% national average:
| Model | Pass Rate | vs National (71.5%) | Tests | Years |

Durability Champions: Which Ds Models Age Best?
Raw pass rates favour newer cars. This ranking compares each model against the national average for cars of the same age:
| Model | Year | Fuel | vs Same-Age Average | Trend | Context |
|---|---|---|---|---|---|
| DS7 | 2019 | Petrol | +0.5% | (87% at 3-4 years) | |
| DS3 | 2019 | Petrol | -2.5% | (84% at 3-4 years) | |
| DS5 | 2016 | Diesel | -3.6% | (79% at 5-6 years) | |
| DS4 | 2017 | Diesel | -7.9% | (74% at 5-6 years) | |
| DS3 | 2017 | Petrol | -8.6% | (74% at 5-6 years) | |
| DS3 | 2018 | Petrol | -8.7% | (74% at 5-6 years) | |
| DS3 | 2016 | Petrol | -9.1% | (69% at 7-8 years) | |
| DS3 | 2018 | Diesel | -9.4% | (73% at 5-6 years) | |
| DS4 | 2016 | Diesel | -11.3% | (72% at 5-6 years) | |
| DS3 | 2015 | Petrol | -11.6% | (66% at 7-8 years) |
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.

Pattern to avoid
Early 2015-2018 diesel/petrol DS3s, 2015-2016 diesel DS4s are the models that drag down Ds's average. These vehicles fail MOTs more often than they pass.

About This Data
This analysis uses real MOT test results from the DVSA database, covering 42,429 tests on Ds 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: 500 tests for proven durability rankings, 1,000 tests for early performer rankings. Pass rates are calculated as first-time passes, excluding retests.
The overall national average MOT pass rate is 71.51% based on 32.3 million tests across all manufacturers. Year-specific averages range from ~59% (2009 vehicles) to ~88% (2020 vehicles).
