Build the inspection planDocumented onset mileage is at or below the ~54k miles an average 2022 car has covered.
Whining or clicking noise during acceleration or regenerative braking on BEV models.
Age, electronics and build-related issues that are not mileage-driven.
Traction battery health variation, particularly on ex-private-hire cars
Rear disc corrosion from regenerative braking

The self-charging hybrid. It suits buyers who cannot charge at home.
Hyundai's warranty transfers with the car when servicing is up to date, which is a strong selling point.
Across all powertrains including HEV, PHEV, and BEV, Hyundai specifies a strict service interval of 10,000 miles or 12 months, whichever comes first. Missing this interval by even a minor margin can void the manufacturer warranty. Ensure the service book shows consistent, on-time stamps before retailing the vehicle.
The facelifted 38kWh BEV uses a specialised low-conductivity coolant for the high-voltage battery system to prevent electrical shorting. This fluid is significantly more expensive than standard engine coolant and requires a specific bleeding procedure using diagnostic equipment. This mandatory change occurs every 40,000 miles or 3 years.
Plug-in Hybrid and Electric models were originally supplied with two cables: a standard 3-pin domestic charger and a Type 2 to Type 2 cable for public or wallbox charging. Replacing missing genuine Hyundai cables costs over £300, so always verify both are present under the boot floor.
