PureTech 1.2 timing belt failure
The three-cylinder 1.2 PureTech engine uses a rubber cam belt inside the engine — rather than a more durable chain — that can deteriorate faster than the stated service interval, particularly in stop-start urban use. If the belt snaps, catastrophic engine damage typically follows. Peugeot introduced revised belt specifications and shorter replacement intervals on later production. Always check the service history for timing belt replacement evidence and ask about the maintenance schedule before purchase.
