Same 5th gear failure as the sister Fiat Ducato: 5th is a bolt-on gear with marginal drip-feed lubrication, and windscreen drainage water entering the gearbox breather emulsifies the oil. The 5th synchro cone and hub wear until the gear jumps out or fails outright.

Where this Peugeot Boxer fault data comes from
If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Peugeot Boxer owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Peugeot Boxer goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
