Vehicle financed declined

I bought a car in 2015 financed by ABSA, but now the car is giving me problems and when I fix this today tomorrow is something else and I fear that I will end up defaulting my payments due its constant break downs, when I apply for a new car I always get declined, can you please assist me get a new car that I will pay with a smile, because I do not want to end up returning it or defaulting my payments. I believe that have spent more than R150 000 on its repairs since I bought it. Please help I am being declined whenever I try to apply for a new one
