Cherry tiggo 4 problems

Bought a new tiggo pro 4 elite from Cherry Alberton on the 21/10/2022. On the 3/11/2022, engine light came on, took it to the dealership who checked out car, reset the computer and told me it was all fine. 6/11/2022 engine light is back on. How is this possible on a car with less than 700kms. Cherry explain.
