Mitsubishi does not honour their warranty.

I bought a new Triton 2.4 DID. Since the day I received the vehicle I have had nothing but problems - 3rd gear jumping out, gearbox oil leaks, damaged clutch plate. The bakkie was at various Mitsubishi dealers - Mitsubishi Centurion, Mitsubishi Beacon Bay and Mitsubishi Pinetown - in total the gearbox was removed 5 times and the gearbox still leaked. Clutch was replaced and 2 months later started slipping again. Mitsubishi Centurion and Mitsubishi South Africa refuse to fix under warranty stating that the vehicle was overloaded. I tow a Sprite Sprint caravan which weighs 760kg. Where is the overloading? I am totally disgusted with the service that I have received. There is no after sale service and the 5 year warranty is not worth the paper it is written on. I would not recommend Mitsubishi to anyone. Mitsubishi does not have the expertise to repair vehicles.
