The quality of Ford cars

In 2012 I bought my first car Ford Focus 2010 model at Lazarus centurion. The car had a problem an alarm for a seat belt was not working and car was showing a danger sign. At Lazarus tried everything but without any success. In 2013 i finally decided to sell the to Lazarus and bought Focus 2013 model. Two year (2016) later I bought ST1. And in 2017 I bought ST3 and in April 2018 I took the car fro service Ford CMH Gezina. Immediately after that the car started to leak oil and it was over flowing. Then I decided to sell it and bought Fusion 2016 model at Ford CMH Gezina last year September. This year (in January) I took it to Ford Pretoria North because it was showing a sign for a safety belt. Three months later I took to Ford PTA North for annual service, hardly five months the RADIATOR of the car is leaking. My question what is wrong with FORD. I have been a loyal customer to your brand but what am I getting in return...
