Peugeot 408 GT S/s PHEV Auto (2023)
2023 Peugeot 408 GT S/s PHEV Auto
CarHunch is tracking 288 2023 Peugeot 408 GT S/s PHEV Auto vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
The 2023 Peugeot 408 GT S/S PHEV is a serious reliability concern at its first MOT, with only an 11.8% pass rate against the UK average of 80%—this is not normal for a one-year-old car and suggests either systemic design issues or widespread quality control problems in this batch. The dangerous defect rate of 0.7% is reassuringly low, but the sheer scale of failures across 288 vehicles indicates buyers should expect significant repair bills early in ownership.
With median mileage of just 21,208 miles, these cars are failing despite light use, pointing to manufacturing or component defects rather than wear and tear. The hybrid powertrain appears to be the weak point; before committing to this model, ask the dealer for documented evidence of what failed on their stock and what remedial work Peugeot is performing under warranty.
We have 288 2023 Peugeot 408 GT S/s PHEV Auto vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 2023 Peugeot 408 GT S/s PHEV Auto
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
