How reliable are DS cars?
Our database covers 4 DS models and 20 documented faults across the range. Of these, 1 are classified as dangerous and a further 14 as major. Dangerous faults are those that can compromise vehicle safety or lead to complete mechanical failure if left unaddressed.
According to DVSA MOT test data, DS models fail at an average rate of 19.2%, sitting below the 22.7% average across all manufacturers in our database. Reliability varies considerably between models. The Ds7 is the strongest performer at just 14.9%, while the Ds4 has the highest failure rate at 22.1%.
If you are considering a used DS, researching the specific model and generation you are looking at makes a real difference. The most common failure areas across the range are transmission and brakes, though each model has its own particular weak points. This page gives you a complete breakdown by severity, the models affected, and what repairs typically cost at UK garages.

Problems by DS model
We track faults across 4 DS models. Each model page includes every known issue, generation-specific details, UK repair costs, and MOT failure data. Select a model below to see its full breakdown.
What to check before buying a used DS
Every used DS deserves a thorough inspection, but knowing the common weak points for your target model gives you a serious advantage. Since transmission faults are the most common across the range, pay particular attention to this area during any viewing or test drive.
The 1 dangerous-rated faults deserve special attention. These include Wet timing belt failure (DS3-CB 1.2 PureTech). Any of these can compromise safety or result in repair bills running well into the thousands.
A complete dealer service history is one of the strongest indicators of how well a DS has been looked after. Many of the faults on this page are preventable or can be caught early through regular servicing. If the seller cannot produce service records, treat that as a significant red flag.
Check the MOT history carefully too. With a 19.2% average failure rate across the DS range, some advisories and minor failures are normal over the life of any car. What matters is the pattern: recurring failures in the same area suggest an underlying problem, while a history of clean passes is encouraging.
DS repair costs: what to expect
Across all documented faults, the average DS repair costs between £234 and £528 at an independent garage. At the top end, the most expensive single repair can reach £2,000 or more. Main dealer rates are typically 30% to 50% higher across the board.
The single most expensive DS repair in our database is DPF blockage and regeneration issues (DS5_Gen1), which can cost £500–£3,000 at a main dealer.
These figures are based on reported UK repair costs and serve as a guide. Actual prices will vary depending on your location, the garage, and the parts required. Getting quotes from two or three specialists before committing to any major work is always worthwhile.
