Frequently asked questions
Which Ford Puma engine is the most reliable?
1.5 EcoBoost (Puma ST) — Maint. Sensitive verdict. The 1.5 EcoBoost three-cylinder in the Puma ST makes it a genuinely fun hot crossover (the same engine family as the Fiesta ST). It's a punchy direct-injection turbo, with the modern cautions: intake-valve carbon over time, turbo/PCV care, and — as with the wider EcoBoost family — careful oil discipline and attention to the belt/cooling. The Fiesta ST 1.5 had some early reliability chatter (and the wider EcoBoost coolant attention), so buy a serviced car with documented oil history. A well-kept ST is a hoot; just treat the oil and cooling seriously.
Which Ford Puma engines should you avoid?
None of the Ford Puma engines listed are rated "Problematic" or "Avoid" — but always check the service history before buying.
