Top issues to watch for

The most serious Peugeot Ion problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion near suspension mounting points (Gen1)
Gen12011–202040k–60k miles
The load-bearing structure within 30cm of suspension mounting points shows significantly higher corrosion rates than the fleet average on this model. This affects the structural integrity around subframe, spring and suspension component mounting areas. The lightweight construction and materials used in this electric vehicle platform appear particularly susceptible to corrosion in these critical load-bearing areas. Structural failure in these areas creates immediate safety risks.
What happens if ignoredStructural failure near suspension mounting points can cause catastrophic handling loss, wheel detachment, or suspension collapse. The vehicle becomes immediately unsafe to drive. Proper structural repairs require specialist welding and may not be economically viable on older examples.

Dangerous
Brake hose ferrule corrosion (Gen1)
Gen12011–20200k–40k miles
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. This issue appears most frequently on low-mileage examples, suggesting a material or design problem rather than normal wear. The ferrule corrosion can lead to brake fluid leaks and complete brake system failure. The trend appears to be worsening in recent MOT data.
What happens if ignoredCorroded brake hose ferrules can cause complete brake system failure without warning. The vehicle should not be driven if ferrule corrosion is suspected. Emergency repair requires immediate brake system inspection and affected hose replacement.

Major
Steering rack gaiter and ball joint dust cover deterioration (Gen1)
Gen12011–202020k–60k miles
Steering rack gaiters and ball joint dust covers deteriorate at 35.6 times the fleet average rate on this model. These rubber boots protect critical steering components from contamination. Once damaged, dirt and moisture enter the steering joints causing accelerated wear and eventual steering system failure. The high failure rate suggests poor material quality or design issues with the protective boots used on this electric vehicle platform.
What happens if ignoredFailed dust covers allow contamination of steering joints leading to accelerated wear, steering looseness, and potential steering system failure. While not immediately dangerous, deteriorated gaiters require prompt replacement to prevent expensive steering component damage.

Major
Brake pipe corrosion (Gen1)
Gen12011–202020k–60k miles
Brake pipes show damage or excessive corrosion at 6.0 times the fleet average rate. This affects the rigid metal brake lines that carry brake fluid throughout the braking system. The electric vehicle's construction or material choices appear to make the brake lines particularly susceptible to corrosion damage. Failed brake pipes can cause complete brake system failure and represent a serious safety risk.
What happens if ignoredCorroded or damaged brake pipes can cause partial or complete brake system failure. The vehicle may lose braking ability without warning. Immediate inspection and repair is required if brake pipe damage is suspected.
