Peugeot 107 Issues: Small Car, Big Surprises Ahead
Peugeot 107 Reliability Problems Owners Keep Reporting
The Peugeot 107, produced from 2005 to 2014, faces persistent reliability issues including premature clutch failure, water ingress into footwells and rear lights, timing chain rattles, and electrical faults, with owners reporting these problems across forums and inspection data showing defect rates up to 30.1% in older models as of 2020. These concerns stem from its lightweight city car design shared with Toyota Aygo and Citroën C1, yet Peugeot variants often suffer higher complaint volumes due to cheaper interior materials and sealing issues. Statistical analysis from MotorEasy Reliability Index scores it a low 9.5 out of 100, with braking system claims at 30% of total repairs averaging £95.41 each.
Common Mechanical Failures
Clutch wear tops the list of mechanical failures in the Peugeot 107, often failing prematurely under 10,000 miles due to the lightweight 1.0-liter Toyota-derived engine's high-revving nature in urban stop-start driving. Owners on Reddit and HonestJohn report slipping gears and difficulty shifting, with ADAC breakdowns highlighting non-durable clutches as the model's biggest drawback since launch in June 2005. Replacement costs average £519.30 per MotorEasy data, accounting for 25% of gearbox claims.
Timing chain rattles emerge around 60,000 miles, caused by chain tensioner wear, reducing performance and risking engine damage if ignored. Water pump failures are frequent, especially post-2010 models, leading to coolant leaks and overheating, as noted in YouTube diagnostics from 2022. Front brake discs and pads wear quickly on the front axle, with rusty exhaust pipes reported in 15% of inspected vehicles per Auto-ABC studies.
- Clutch slips under load after 20,000-50,000 miles in 25% of claims.
- Timing chain noise signals tensioner failure, fixable for £300-£500.
- Water pump leaks affect 10-15% of high-mileage examples.
- Brake discs warp by 30,000 miles due to poor heat dissipation.
- Exhaust corrosion starts at rear sils after 5-7 years exposure.
Water Ingress and Cabin Issues
Water leaks plague the Peugeot 107's cabin, with footwells flooding from poor door seals and rear high-beam light units allowing ingress, a problem PSA acknowledged but ceased supplying parts for after 2018. Owners fix this by applying rubber draft excluders or silicone-free sealants, as detailed in 2020 Reddit threads, preventing electrical shorts and mold growth. Rear windscreen rubber drying out exacerbates this, with spare wheel wells collecting water unless bungs are removed.
Corrosion targets rear axle mounts and sills, with 22.8% defect rates in 12-year-old models per 2021 inspections, below average for peers. These issues degrade resale value by 20-30% on models over 100,000 miles, per used market analyses.
| Issue | Average Repair Cost | % of Claims | Frequency (Miles) |
|---|---|---|---|
| Clutch Failure | £519.30 | 25% | 20k-50k |
| Water Ingress | £146.85 | 15% | Any age |
| Braking System | £95.41 | 30% | 30k |
| Suspension Wear | £228.00 | 20% | 50k+ |
| Electrical Faults | £48.00 | 5% | Variable |
Electrical and Steering Problems
Electrical gremlins affect 15% of Peugeot 107s, including power steering failures during low-speed maneuvers and faulty rear lights from water damage. MyCarly community logs these as top issues, with sticking throttle pedals and drum brake noise compromising safety. Front stabilizer struts wear out, causing knocking over bumps and handling instability.
"The main problem is the rear high-beam light; its seal dries out. PSA no longer sells the light separately, so you'll need to replace the whole unit, which costs about £35." - Reddit user, September 2020.
Inspection and Reliability Statistics
Germany's vehicle inspection service reported 13.1% average failure rates for Peugeot 107s from 2010-2021, rising to 30.1% for 12-year-olds in 2020, slightly above peers at 29.51%. Peugeot ranked 31st in 2013 Driver Power surveys, just above last place, though its Toyota Aygo sibling scored higher at 146th. Euro NCAP awarded three stars in 2005 for lacking modern safety tech like stability control.
- Check clutch operation during test drive; listen for slips or rattles.
- Inspect footwells and rear lights for water damage signs.
- Examine sills and axle mounts for corrosion pitting under paint.
- Test power steering at low speeds for failures.
- Review service history for timing chain and water pump changes.
Historical Context and Model Timeline
Launched in June 2005 as a badge-engineered city car on Toyota's platform, the Peugeot 107 shared 998cc engines proven reliable up to 150,000 miles but suffered Peugeot-specific build variances. A 2012 facelift added minor equipment but didn't resolve clutch or leak issues persisting to end-of-production in 2014. Post-2020, parts scarcity for lights and seals has driven DIY fixes among owners.
Compared to rivals, the 107's fuel economy shines at 6L/100km petrol, but noisy cabins and small 139L boots detract, with crash safety lagging modern standards. MotorEasy's monthly updates as of 2026 confirm braking and gearbox dominance in claims.
Owners mitigate risks by proactive sealing and clutch checks, preserving the 107's appeal as a cheap-to-run urban runner. Data from 2021-2026 shows consistent patterns, urging pre-purchase inspections. French TÜV equivalents mirror these at 14.4% failure averages for early models.
Steering faults, though rarer, spike in low-speed scenarios, per MyCarly, while catalytic converter cracks sap power if aftermarket units degrade. Fuel system claims at 5% (£156) tie to throttle sticking.
In summary of owner sentiment, 100% reliability claims persist for well-maintained examples, but neglect amplifies issues like exhaust rust and brake wear. Peugeot's post-warranty support lags, pushing independent garages for economical fixes.
Everything you need to know about Peugeot 107 Issues Small Car Big Surprises Ahead
Are Peugeot 107 clutches prone to early failure?
Yes, clutches fail prematurely in 25% of claims, often under 50,000 miles due to urban driving stress, costing £519 average to repair. Larger 7-inch replacements post-2010 improve longevity, per HonestJohn reviews.
Does the Peugeot 107 suffer water leaks?
Water ingress affects footwells and rear areas from seal failures, fixed via rubber excluders or resealing, impacting 15% of electrical claims.
How reliable is the engine overall?
The Toyota-sourced 1.0L engine excels beyond 100,000 miles with chain drive, but auxiliary components like water pumps fail frequently.
Is corrosion a major issue?
Rear sills and axles corrode post-7 years, with 22.8% defect rates in inspections, worsened by leaks.
What's the repair cost landscape?
Average claims hit braking at 30% (£95) and suspension (£228), keeping total ownership costs low versus rivals despite 9.5 reliability score.
