Things to check

UK recall R/2021/087: 1,214 Ioniq Electrics built June 2019 to January 2020 may have a battery short circuit. The charge level is limited first, then the whole battery is replaced. Ask for proof of a new battery. check-vehicle-recalls.service.gov.uk
Initial step to limit the charge state followed by eventual complete replacement of the battery assembly.
US recall 21V-127: two 2020 Ioniq Electrics have the same battery short-circuit risk. The charge limit is lowered to 80% until the battery is checked and replaced if needed. Check the VIN. api.nhtsa.gov
The lithium-ion (Li-ion) battery may short-circuit.
UK recall R/2026/159 (June 2026): 8,299 Ioniq Electrics built December 2018 to July 2022 get a battery software update because cell voltages can drift apart. Until then, park in a well-ventilated place. check-vehicle-recalls.service.gov.uk
Some vehicles fitted with a high voltage battery may have internal cell voltage deviation.
UK recall R/2018/297: 5,151 early Ioniqs built July 2016 to July 2017 get new power relays (thermal risk). Check it was done. check-vehicle-recalls.service.gov.uk
Power relay connections with increased risk of a thermal incident.
UK warranty: if the car was ever a taxi, private-hire or driving-school car, the battery warranty is only 5 years / 100,000 miles. Check the V5C history. dmassets.hyundai.com
the battery warranty is five years or 100,000 miles, whichever comes first
