What goes wrong, what it costs, and what to check before you buy a used DS DS7.
The DS DS7 occupies a niche position on the UK market.
We track 5 known issues across the DS DS7 range, with 4 classified as significant. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

DS7-Gen1 (2018–2022) — Petrol options included the 1.2 PureTech turbo, 1.6 PureTech turbo, with 1.5 BlueHDi on the diesel side. We track 5 known issues on this generation, with 4 classified as significant. The most significant concern is CV joint boot deterioration (£100–£200 to address).
The constant velocity joint rubber boots on driveshafts fail at significantly higher rates than the fleet average, particularly on 1.6 petrol models. MOT data shows failure rates peak at 8.8 times the national average between 20,000-40,000 miles with a worsening trend. Boot failure allows grease to escape and dirt to enter the CV joint, leading to expensive driveshaft replacement if caught too late.
A split boot allows the CV joint to fail within months if not repaired. CV joint failure causes clicking during turns and eventual complete driveshaft failure. Boot replacement costs £100-200 per side if caught early. Full driveshaft replacement costs £300-500 per side plus labour.
Listen for clunking or vibration from underneath when pulling away or changing direction. Check for play in the driveshafts by rocking the car in gear with the handbrake on. Worn CV boots are a telltale sign — look for grease splatter around the inner wheel arch.
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. The issue appears to be improving in more recent production.
Worn suspension components affect handling, tyre wear patterns, and MOT compliance. Individual components typically cost £50-150 each but multiple items often need replacement simultaneously. Poor handling compromises safety particularly in emergency manoeuvres.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
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. This affects both engine variants and shows a worsening trend across the data period. The high failure rate suggests either soft pad material or aggressive brake system calibration.
Worn brake pads reduce braking effectiveness and can cause expensive brake disc damage if ignored. Pad replacement typically costs £100-200 per axle but disc replacement adds £200-400 per axle if damage occurs. Complete brake pad wear creates a dangerous vehicle.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
Brake discs become excessively weakened, insecure, or fractured at 2.3 times the fleet average rate, often on low-mileage vehicles. This occurs alongside the premature brake pad wear issue and suggests either poor disc material quality or excessive heat generation. The trend is worsening according to MOT data.
Damaged brake discs compromise braking performance and create a safety risk. Disc replacement costs £200-400 per axle plus labour. Severely damaged discs can fail completely, causing total brake loss on the affected wheel.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
The exhaust system develops leaks or becomes insecure at 3.3 times the fleet average rate, particularly affecting 1.6 petrol models between 20,000-40,000 miles. This likely reflects corrosion issues with the exhaust system materials or mounting points rather than impact damage given the consistent mileage pattern.
Exhaust leaks reduce efficiency and can allow harmful gases into the cabin if the leak is forward of the rear axle. Complete exhaust failure is an MOT failure and makes the car illegal to drive. Repair costs vary from £50 for minor leaks to £400+ for full system replacement.
Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.

Based on 7k real DVSA MOT tests, the DS DS7 fails more often than average on several items. The biggest outlier is transmission shaft constant velocity joint boot... at 9x the fleet average, followed by suspension pin, bush or joint worn (9x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full DS DS7 MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 12k miles) typically costs £80–£120 at an independent garage.
The bigger-ticket items to budget for include automatic transmission fluid (£200–£300).
