Problem Car

We bought a brand new Izuzu KB240 Double Cab end of December 2016. Ever Since we bought the vehicle we have had endless issues and problems. Each and every time they need to repair things on the vehicle. At the passenger side it gets so hot you cannot put your feet on the carpet, you need to keep it on the side. We have taken the vehicle in for them to feel and they say it does not make sense. WELL SOMETHING IS WRONG! Again today we had to take it in to get a new fuel pump & radio (WHICH THEY AGAIN DID NOT ORDER) The rubberizing is busy peeling - and they say they cannot take responsibility for that? REALLY? We paid you for it it is a year later! The parts is packing up and each time they just fit a new one .... I AM NOT HAPPY I BOUGHT A NEW CAR NOT A SECOND HAND CAR! If my warranty is done .... who will take responsibility for this if so many things are changed on the vehicle? It is a fuel tank, fuel sensors, fuel pump, radio, car overheat at the bottom of passenger side, and so many more issues!!!! I have complained so many times to Gerhard - but it is water on a ducks back! He just pulls up his shoulders. I have asked to have a meeting with the regional and dealer principal but again - nothing happens. I would not recommend anyone to buy this car as there is serious issues with it and absolutely no after sales service. Before the deal Gerhard was super nice and said any issues and they will solve it - well we have MAJOR issues and nothing gets done - just a new part fitted and no answers. I am sorry but I cannot and will not accept this. Who is going to take responsibility if the warranty is done? There is already so much repairs done on this vehicle
