Engine reimbur*****t Ford

In 2018 June I bought a Ford Focus from CMH Ford Durban. I drove the car for 2years then in 2021 March it had an engine misfire and the engine had to be replaced. I drove the car 14 months and again it has the same problem this year July engine Misfire and the engine has to be replaced. Now this clearly shows the quality of the car or it’s engine is not of good standard. The car is less than 100k mileage and it’s gonna have a third engine. Ford have to reimburse me for this engine because the new engine they fitted last year did not even finish 20k mileage and only lasted 14months. It is unfair on a customer side to have to keep paying for Ford malfunction error in such a short period of time.
