Common Problems with the
2021 Genesis G70

The G70 arrived in the UK in 2021 as Genesis's sports saloon rival to the BMW 3 Series, sharing its mechanicals with the proven Kia Stinger. Early models had a turbo oil feed pipe recall for potential fire risk, and headlight condensation was a common complaint. Brake shudder on Brembo-equipped cars is often caused by pad deposits rather than warped discs.
