Hyundai Bayon FAQs
How many Hyundai Bayons are there in the UK?
23,735 Hyundai Bayons were licensed in the UK at the end of June 2026, with a further 74 declared off the road (SORN), according to DfT vehicle licensing statistics.
Is the Hyundai Bayon reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is an 84.9% first-time pass rate for the Hyundai Bayon across 5,491 tests in 2025, above the 72.3% average for all cars.
What should I check before buying a used Hyundai Bayon?
On the car itself, start with the areas it most often fails on: visibility, lamps, reflectors and electrical equipment and tyres. Then check the individual car's own records. Outstanding finance, insurance write-offs and police stolen markers are not part of the MOT record, so they take a history check.
How do I check a Hyundai Bayon's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.

MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), which also gives the engine sizes. Licensed, SORN, fuel and registration figures are from the Department for Transport vehicle licensing statistics (VEH0120, VEH0124, VEH0160). Government data is used under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability. History-check findings are anonymous counts from reports bought on Carpeep, each vehicle counted once, and are published only where at least 100 vehicles returned an answer.
