Top issues to watch for
The most serious Peugeot Horizon problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Major
Front coil spring failure
Coil spring fractures occur at over 21 times the national average, particularly affecting petrol variants from very low mileage. The failure pattern suggests inadequate spring steel quality or incorrect spring rate specification for the vehicle weight. Spring failures from new indicate a fundamental design or manufacturing defect. The high failure rate across both engine variants suggests a common suspension supplier or specification issue.
What happens if ignoredA broken coil spring affects vehicle handling and braking stability, creating a direct safety risk. The broken spring can damage the tyre, shock absorber, or brake lines. The vehicle should not be driven with a known broken spring due to unpredictable handling characteristics.

Major
DPF regeneration and emissions system failure (Diesel)
The 1.6L diesel shows severe emissions test problems with smoke opacity levels exceeding limits at nearly 29 times the national average, plus high rates of emissions tests being impossible to complete. This indicates widespread DPF (diesel particulate filter) blockage and regeneration system failures. The pattern is typical of DPF systems that cannot complete regeneration cycles due to short urban journeys or faulty sensors.
What happens if ignoredA blocked DPF prevents the car from passing the MOT emissions test and can cause engine warning lights, reduced power, and poor fuel economy. Professional DPF cleaning costs £200-400. Complete DPF replacement costs £1,500-2,500. Continued driving with a failed DPF can damage the turbocharger and other engine components.

Minor
Exhaust system leaking or insecure
The exhaust system on both 1.6L petrol and diesel variants shows exceptionally high failure rates across all mileage ranges, peaking at over 31 times the national average on low-mileage diesel examples. The failures appear to affect exhaust mounting brackets, flexible sections, and joint sealing throughout the system. This suggests either inadequate corrosion protection or poor-quality exhaust components fitted from the factory. The pattern affects cars from new, indicating a design or manufacturing issue rather than normal wear.
What happens if ignoredExhaust leaks cause noise, potential carbon monoxide ingress into the cabin, and MOT failure. Complete exhaust system replacement may be required on higher-mileage examples where corrosion is extensive. Mounting failures can cause exhaust damage from contact with the road surface.

Minor
CV joint boot failure
CV joint boots fail at over 23 times the national average, with both missing boots and severely deteriorated boots showing as common MOT failures across all mileage ranges. The high failure rate from low mileage suggests poor-quality boot material or inadequate clamp design. Once the boot fails, contamination destroys the CV joint within a few thousand miles, requiring complete driveshaft replacement rather than simple boot renewal.
What happens if ignoredFailed boots allow dirt and water into the CV joints, destroying them within a few thousand miles. This requires complete driveshaft replacement costing £300-600 per side. Early boot replacement prevents joint damage and costs significantly less than waiting for joint failure.
