DS Ds7 MOT Failures
An analysis of 3,203 real DVSA MOT tests on the DS Ds7 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: DS7-Gen1 (2018–2022).
Where the DS Ds7 fails its MOT
The single biggest MOT failure point on the DS Ds7 is transmission shaft constant velocity joint boot... — this model is 8.8 times more likely to fail on this item than the average car on UK roads. That makes it worth watching for anyone buying or owning this model. Across 3,203 MOT tests, 2.61% of all DS Ds7 tests recorded this as a failure.
Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.
The failures span 2 categories: Bodywork, Suspension. If you're inspecting a DS Ds7 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that DS Ds7 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
CV joint boot deterioration (DS7-Gen1) Major
The constant velocity joint rubber boots on driveshafts fail at significantly higher rates than the fleet average, particularly on 1.6 petrol models. Affects DS7-Gen1; typical independent garage repair cost is £100–£200.
Suspension component wear (DS7-Gen1) Major
Suspension pins, bushes, and joints show excessive wear rates compared to other vehicles, with MOT failures peaking at This affects both petrol and diesel variants and suggests either poor component quality or inadequate protection from road conditions. Affects DS7-Gen1; typical independent garage repair cost is £150–£400.
Premature brake pad wear (DS7-Gen1) Major
Brake pads wear to below the legal 1.5mm thickness at 3.7 times the rate of the average vehicle, with failures documented from very low mileages. Affects DS7-Gen1; typical independent garage repair cost is £100–£200.
Brake disc deterioration (DS7-Gen1) Major
Brake discs become excessively weakened, insecure, or fractured at 2.3 times the fleet average rate, often on low-mileage vehicles. Affects DS7-Gen1; typical independent garage repair cost is £200–£400.

What to check before buying a DS Ds7
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a DS Ds7:
Bodywork — check for transmission shaft constant velocity joint boot.... Suspension — check for suspension pin, bush or joint worn.
Beyond the MOT items, ask specifically about cv joint boot deterioration and suspension component wear. These won't show up on a standard MOT but can be expensive to fix — repairs start from £100. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
