Overall, the used 2021 Trumpchi GS4 has no widespread severe reliability issues or common problems reported by owners. Individual cases of right front axle half-shaft abnormal noise have been documented in some user feedback, with a few instances requiring replacement within 33,000 kilometers. However, these are isolated incidents rather than a universal problem, which reinforces that this model is generally reliable for those looking to buy used cars.
