Brand New Suzuki Swift 1.2 GL

I bought a brand new Suzuki Swift 1.2GL from Penta Menlyn group on the 9th of September 2022. On the 22nd of September 2023 I took the car back to the dealership because it was flashing the engine and key light and it would loose power. I was told nothing was wrong with the car. The light persisted and I took the car back 22/10/2022 and I was told the battery terminal was loose. The light continued to come on and I took it back on 13/12/2023 I was told to pour R300 fuel so they can drive the car so that they can see the light and try replicate it. I was told the light did not come on and the was nothing they can do until they can see the light.27/01/2023 I took the car back to the dealership I was told they drove the car for 64km and the diagnostic machine could not pick up anything, I engaged the dealership manager and dealership principal yesterday 30/01/2023, the dealership manager William said maybe we should try removing the tracker maybe it’s the one that is causing the problem.The dealership principal said maybe it’s not a mechanical problem maybe the fuel I pour is in the car is of poor quality or it’s rodents. I also tried to engage the Suzuki head office I spoke to Celumusa but he told me to remove the tracker and allow them a chance to fix the car but I have been giving them 4months to find the problem and I still have not been assisted.
