Terrible feedback and assistance

I bought my Chery Tiggo 4 pro CVT in February 2023 out of the box. To have endless issues with the service done on my car, or should I say service not done. I have now taken my car for about the 7th time asking about my fuel consumption and why my engine light comes on a week after they have so called attended to the issue. At 43000KM my brake booster has given in and for a part that is supposed to last a lifetime of my vehicle, obviously there is something wrong with the vehicle, or it was a demo that had the data cleared.

For a brand new car to give such issues is a big worry, not impressed by the way these issues are being resolved as being **** to by service advisors and mechanics regards the information on what the issues are with the vehicle.
