Misleading and lies

My name is Riedewaan Smith with id number ***,i took delivery of a Mercedes Benz C200 from MIB auto on the 8/09/2021,prior to taking delivery i took the vehicle for a test drive and noticed the enjin light was on and the brakes was a bit low,i asked the dealsership about it and his response was i quote "dont worry i will sort it out "on the day of delivery when i collected the vehicle from the showroom floor the enjin light was gone as i drove down the road the enjin light came back on i immediately sent a pic to the dealer to show him the enjin is back on his response was to me i quote "its only a dirty sensor and all will be ok"i then listened to him but still feeling very uncertain, i noticed a sqweeking sound by the right rear wheel i took it to a workshop recommended by the dealer ,it was discovered the park brake spring mechanism was broken that why it was sqweeking. I then took the vehicle for a diagnostic test at my own cost as felt very uncomfortable because of the enjin light that is on the diagnostic report came back with a faulty o2 sensor and 4 faulty coils and plugs,i am since then trying to get assistance to have these items repaired i only drive this car weekends ,i called the warranty place they said i must go to the dealership as i have a 3 month warranty i callled the insure africa but they told me i have a shortfall plane with. I feel this is unfair towards me i pay almost a R6000 instalment now i must still pay for damages that is not my fault,this is not on.Also the rain water drips into the vehicle,i have the vehicle a month now.I have all the communication between myself and the dealer,the dealer is also not of much assistance to me.Could you please assist me in this regard.Thank you.Riedewaan Smith ***.

Kind regards R.Smith
