Peugeot Ion MOT Failures
An analysis of 4,706 real DVSA MOT tests on the Peugeot Ion — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Gen1 (2011–2020).
Where the Peugeot Ion fails its MOT
The single biggest MOT failure point on the Peugeot Ion is track rod ends worn — this model is 36 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 4,706 MOT tests, 11.06% of all Peugeot Ion tests recorded this as a failure.
Steering faults include worn track rod ends, power steering leaks, and rack wear. These are safety-critical — any play in the steering should be investigated immediately.
Other notable weak points include suspension joint dust cover severely deteriorated (35x the fleet average), abs fault (18x the fleet average), brake hoses perished or damaged (37x the fleet average), and seat mounting fault (35x the fleet average). These ratios compare the Peugeot Ion's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Steering, Suspension, Brakes, Seatbelts & Airbags, Bodywork. If you're inspecting a Peugeot Ion 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 Peugeot Ion specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion near suspension mounting points (Gen1) Dangerous
The load-bearing structure within 30cm of suspension mounting points shows significantly higher corrosion rates than the fleet average on this model. Affects Gen1; typical independent garage repair cost is £800–£2,000.
Brake hose ferrule corrosion (Gen1) Dangerous
Brake hose ferrules (the metal crimped ends that connect flexible brake hoses to rigid brake lines) show exceptionally high corrosion rates on this model, failing at 36.8 times the national fleet average. Affects Gen1; typical independent garage repair cost is £150–£300.
Steering rack gaiter and ball joint dust cover deterioration (Gen1) Major
Steering rack gaiters and ball joint dust covers deteriorate at 35.6 times the fleet average rate on this model. Affects Gen1; typical independent garage repair cost is £120–£250.
Brake pipe corrosion (Gen1) Major
Brake pipes show damage or excessive corrosion at 6.0 times the fleet average rate. Affects Gen1; typical independent garage repair cost is £200–£400.

What to check before buying a Peugeot Ion
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Peugeot Ion:
Steering — check for track rod ends worn. Suspension — check for suspension joint dust cover severely deteriorated, abs fault, subframe bushes or mounts worn. Brakes — check for brake hoses perished or damaged, significant brake effort recorded with no brake....
Beyond the MOT items, ask specifically about structural corrosion near suspension mounting points and brake hose ferrule corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £800. 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.
