The 2020 Peugeot 308 petrol models are genuinely reliable, with a 90.1% first-time pass rate that sits well above the UK average, but diesel versions tell a completely different story at just 63.9%—a 26-point gap that makes fuel choice critical if you're considering this car. Only 11.4% of vehicles have ever recorded a dangerous defect, so structural safety issues aren't a widespread concern here.
At a median mileage of 26,457 miles for a four-year-old car, these are fairly lightly used examples, which partly explains the solid petrol reliability. The average 2.6 advisories per vehicle suggests minor maintenance creep rather than serious mechanical problems, so budget for routine upkeep but don't expect major surprises—if you're looking at one, verify the fuel type first and strongly favour the petrol variants.
The 2020 Peugeot 308 passes its MOT first time more often than most UK vehicles (90.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 3,491 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
