Peugeot 408 II 225
Model overview
The Peugeot 408 II is a new-generation fastback with limited long-term reliability history. Petrol, plug-in hybrid and electric versions differ substantially, so condition and documented, powertrain-specific servicing are important.
Pros
- Distinctive fastback styling with hatchback practicality.
- Modern technology and broad powertrain choice.
- Efficient petrol, hybrid and electric versions available.
Cons
- Complex electronics may be costly to diagnose.
- Ride and tyre costs vary with trim and wheel size.
- Electrified versions need careful charging and software records.

Maintenance
Use the VIN- and engine-specific Peugeot servicing schedule. Electric versions still need scheduled checks of brakes, cooling, charging and other non-drive systems.
Engine overview · 1.6L PLUG_IN_HYBRID
The 1.6-litre plug-in-hybrid system offers strong electric-assisted performance, but long-term evidence is still limited and condition depends on charging hardware, software, battery health and careful servicing.
Pros
- Responsive combined petrol-electric drive.
- Potentially low petrol use when regularly charged.
Cons
- More complex than a conventional petrol engine.
- Charging access strongly affects efficiency.
- 180 and 225 versions are not identical calibrations.
Common problems & ownership concerns
Potential impact: Low · Medium · High. This describes possible consequences, not fault likelihood.
- Plug-in charging and hybrid control software issuesMedium
- 12-volt battery or low-voltage supply faultsMedium
- Petrol-engine cooling and lubrication-system leaksMedium
- High-voltage battery condition and thermal-management concernsHigh
Maintenance
Follow the VIN-specific schedule, use specified fluids and charging equipment, keep software updated, and use trained technicians for high-voltage work.
These are general ownership concerns, not a diagnosis. Equipment and engine details vary by version and production date.
