• Official figures from laboratory type-approval tests. VCA says they may not be achieved in real-world driving, and should not be used to rank cars with similar figures.
• Engine sizes are rounded to the nearest 0.1 litre. A version is one line in VCA’s data (description, gearbox, engine and fuel), counted once however many years it was listed. Matched from VCA’s model names “Bayon”, “Bayon MY23”, “Bayon MY25”, “Bayon MY26”. How we use VCA’s figures.

Hyundai Bayon safety recalls

We found no recalls for the Hyundai Bayon in DVSA’s records since 1992. That does not mean none apply: DVSA sometimes records a recall under a range or chassis name we cannot match to a model. Check a specific car on GOV.UK’s vehicle recall check.

A recall applies to cars built on particular dates or with particular VINs, not to every Hyundai Bayon. The details come from manufacturers through DVSA, which says they may be delayed or incomplete. To check a specific car, use GOV.UK’s vehicle recall check or ask the manufacturer or a dealer. How we match recalls to models.
